Wire EDM 101

Wire EDM refers to wire electrical discharge machining. It uses a wire electrode that travels through the conductive work piece. The electrically charged wire is monitored by a Computer Numerically Controlled system or CNC.

Wire EDM removes a part of the material from the work piece, by spark erosion. In this process the wire never comes in contact with the work piece. The electrically charged wire leaves a path on the work piece, which is slightly larger than the wire itself.

The gap between the wire and the work piece generates high voltage electrical pulses. The high voltage and the controlled spark melt and vaporize a small part of the work piece. Each spark produces a temperature of 10000 C, where the energy turned out by the power supply decides the size of the spark penetration into the material.

Wire EDM are basically developed for the tool & die industry. The improvement in the cutting speed, reliability, unattended operation and accuracy is making it very popular in many industries, such as the aerospace, automotive, defense and electronics.

The dielectric fluid acts as an insulator and a flushing agent, during the cutting process. Further through the process of flushing, the dielectric fluid is emitted through the upper and lower heads of the machine. The pressurized fluid also helps in removing the eroded material produced by sparks.

Wire EDM promises high precision as it produces a profile accuracy of 0.00004'. It depends on the quality of the EDM and enables high finish standards obtaining surface finishes 8 micro inches.

The multiple work piece set- up and unattended operation saves a lot of time, which can be utilized on other job functions. The wire EDM system is very cost effective and can be operated at around $4 per hour, in normal cutting conditions.

Wire EDM Parts

Wire electrical discharge machining is mainly used to cut intricate shapes and designs in hard metals. These are otherwise difficult to form, mold or even manipulate. The system is the result of the assembly of skillfully designed parts.

The Chiller is a very crucial part of wire electrical discharge machining and it plays a significant role in operation, as it maintains the appropriate temperature in the system. The flushing is important for the movement of the wire electrode while cutting a piece and the flush cups enhance a smooth process.

The wire electrical discharge machining would make no sense without the EDM wires. These wires are the basis of the system. They act as electrodes in separating the material from the conductive piece. EDM wires are available in various qualities. Each come in different coating and time improvised, for better cutting. EDM wires are available in zinc, copper, tungsten and brass. EDM wires are available in different sizes for specialized cutting. A thinner wire creates a narrow slit or space than the thicker ones. Nowadays, many manufactures are using high performance brass wires, which are alloyed with a larger proportion of zinc, which enables faster and superior cutting.

The patterns are designed on a computer in the CNC system. It is upgraded with software, which enables fine cutting. The CNC system is programmed with advanced software, such as the CAD and CAM. The power- feed contacts are also essential and are exclusively made from tungsten.

Filtration is another important process in the operation of wire electrical discharge machining. It helps to reduce the cost of operation. Various kinds of filter systems are available with different filter cartridges, which mainly assist in increasing the efficiency. The wire electrical discharge machining is designed to suit the diverse needs of the manufacturing sector.

EDM Machining

EDM machining actually stands for electrical discharge machining. This is the term used for a machining process that is used in the process of manufacturing those parts that are made from very hard metals and their alloys. Some of the parts or objects that are produced with the use of EDM machining include dies made of hardened steel, critical components of engines and compressor blades of jet engine fans. EDM machining is a thermal process that is able to remove as well as re-deposit material on top of the object that is being machined. The area that is recast is characteristically much tougher than the regular or original surface. It also will have a desirably higher resistance to wear and tear like abrasion and corrosion.

In the process of EDM machining, an electrical discharge is made to occur between the object surface and the tool used for finishing. This discharge induces high temperatures that range between 10,000 to 20,000 degrees centigrade. In this manner a dielectric field is created that, as long as it exists, it constantly removes and then re-deposits material to the object's surface. The process allows you to introduce metal or elemental powders into the dielectric stream and this causes an alloy to be deposited.

EDM machining is a process that is also put in use in order to cut, shape and alter exceptionally hard metals. It is used to turn metals into tools that can in turn be used to cut and machine those objects that are made from softer metals. In this kind of machining, a wire that is electrically charged is moved extremely close to the object that is under machining and it is at that point that the electrical discharge actually begins. EDM machining is a technology that is extremely useful to mechanical industries today and is used in almost all tool making and metal cutting processes.

Precision Machining

Precision machining is a process that is used to produce a large number of both large as well as small objects that we make use of in our daily lives. Each intricate and detailed piece that makes up an object needs the touch of a machinist's skills. Similarly, a machine or tool that is worn down will require the action of machine tool calibration quite frequently. There are also other facilities provided by precision machining apart from calibration. These would be detailed welding or grooving carried out by a precision machinist. Ranging from aircraft aluminum alloy production right till devices for surgically drilling of bones precision machining caters to almost every industry and technology. Put simply, if an object is made of parts, it would have needed precision machining.

While the majority of precision machining companies usually work with one form of CAD/CAM programs or another, they still do often work with sketches that are hand drawn. Although the hand sketches are usually made use of only in the initial phases of a design. Precision machining can be used on a variety of materials that include graphite, bronze, steel, plastics and glass to name just a few. Based on the project size and the materials that are to be used, different kinds of precision machining tools are put to use. Precision machining is indispensable to numerous industries and various kinds of technologies. Without precision machining we would be unable to manufacture a number of detailed and intricate parts of various objects. The detail and accuracy it brings into the manufacturing procedure is what renders precision machining as so indispensable. There is a long list of machining companies that specialize in precision machining and you can use the Internet to locate them and avail their services. Precision machining is an integral part of mechanical and manufacturing industries.

Trion Mini Mist Eliminator Protects Employees and Equipment

Trion, a division of Fedders Corporation, has developed an innovative mist collector called the Mini Mist Eliminator (Mini M.E.). Virtually all screw machines, CNC machines, surface and centerless grinders use water-soluble, synthetic and petroleum coolants to protect cutting tools and parts. The mists associated with these coolants can be harmful to the health of the machine operator through inhalation and contact with the skin and eyes. Based on potential health risks, the National Institute for Occupational Safety and Health (NIOSH) has established recommended exposure limits for oil mist.

The Mini M.E. removes oil mist from the air by utilizing the principle of electrostatic precipitation. This principle involves drawing the oil mist through an impinger which removes a majority of the mist, especially large droplets. The remaining mist is drawn through an ionizing section, charging the remaining mist particles which then pass through oppositely charged collector plates. The charged mist particles are attracted to the collector plates like a magnet. These particles then drip back down to be recaptured or drained away. The dirty collector plates can be simply washed clean, eliminating costly filter replacements.

The Mini M.E. also eliminates the need for extensive duct work because it can be easily mounted on the machine, platform or ceiling. This also helps to free up floor space. The Mini M.E. can help save on energy costs by being wired directly to the machine tool control, operating only when the machine tool does. It also helps to reduce maintenance costs by protecting equipment from oil mist.

This quality unit not only traps and removes the oil mist, but also the smoke associated with cutting tools and grinders. The Mini M.E. cleans and recirculates indoor air with up to 95% efficiency rate on 0.3 micron particles. It also offers a great advantage in that it can be seamlessly integrated into pre-existing machine tool systems.

Trion is one of the most trusted names in air purification systems. Trion has produced high quality products for industrial, commercial, military and residential markets since 1947.

Adverse Health Effects Of Oil Mist In Machine Tool Industries

Manufacturing environments that use oil-based cutting fluids often put workers health at risk. Applications such as CNC machines, screw machines and surface and centerless grinders produce an oil mist from the coolant used to keep cutting tools from overheating. Oil mist, also known as cutting oil or metalworking fluid, is an oily liquid aerosol dispersed in the air. Fine oil mist hangs in the air for long periods, similar to tobacco smoke.

It has been estimated that up to one million workers in the United States are exposed to oil mist. The health effects of exposure to oil mist have been studied for several decades. Many Epidemiological studies have indicated that long-term exposure to oil mist can lead to increased susceptibility to several types of cancer.

The following diseases have been associated with exposure to oil mist: skin ? oil acne, contact dermatitis, and photosensitive allergic dermatitis; respiratory system ? rhinitis, bronchitis, bronchial asthma, lipoid pneumonia, lung fibrosis and lung cancer; scrotum ? benign and malignant tumors. According to the National Institute for Occupational Safety and Health (NIOSH), potential symptoms of exposure to high concentrations of oil mist include eye and skin irritation, shortness of breath, vomiting, fever, rapid heartbeat and a burning sensation in the mouth, throat and stomach.

Industrial workers are exposed to oil mist by three avenues; skin exposure, aerial exposure and ingestion. The most frequent route of exposure is the skin. Occupational health experts believe that over three-quarters of all occupational diseases are caused by skin contact with oil mist. Oil mist by itself can be dangerous, but it can also quickly become contaminated with foreign material and chemicals which are aerosolized into mist. Many of these contaminants add to the hazards associated with oil mist.

In today?s highly competitive global economy, manufacturers feel pressured to increase productivity. Making machines work harder and faster often produces even more oil mist in the workplace. Even though production schedules may increase, profitability may suffer due to work-related illnesses. Sick employees don?t help the bottom line, they lower productivity and increase overhead costs.

Benefits Of Using Oil Mist Eliminators In The Metalworking Industry

Today's high-performance CNC machines operate at extremely high rates of speed, requiring an oil mist eliminator to remove vast amounts of coolant. For example, the Haas MDC-500 Mill DrillCenter features a high-volume coolant pump and a 40-gallon coolant tank. Mist eliminators are designed to remove the oil mist and smoke from cutting fluids in metalworking environments.

The health hazards of oil mist exposure associated with the machine tool industry have been well documented. The websites for OSHA, NIOSH and the CDC provide a wealth of valuable information for both employers and employees regarding safety issues and cutting fluids.

One of the most common afflictions of workers exposed to oil mist is Hypersensitivity Pneumonitis (HP). This is an allergic reaction to machine coolant that worsens with continued exposure. HP is caused by microbes in the cutting oil that affect air sacs in the deepest part of the lung. Symptoms include fever, chills, deep coughing and shortness of breath.

A mist eliminator collects and removes the harmful particles and smoke from oil mist. Not only does an oil mist eliminator protect workers health, it can also help increase production and improve your shops overall environment.

Oil Mist Eliminator Benefits:

* Potential health problems and lost man hours are reduced by capturing harmful airborne mist particles

* A good quality mist eliminator will help your shop to be in safety compliance with OSHA and NIOSH airborne oil mist limits

* Using a mist eliminator reduces maintenance costs by keeping exposed areas free from oil

* Your production can be increased by reducing machine downtime. A mist eliminator protects the contacts in electronic equipment from becoming fouled by removing the oil mist from the air

Precision Metal Component Manufacturing

Precision metal component manufacturing provides us with numerous products, yet many of us have no idea what ?precision metal component manufacturing? actually means. The goals of this article are to particularize the process, explain the various methods of component manufacturing and provide examples of products created using precision metal component manufacturing.

The general term ?precision metal component manufacturing? can refer to numerous methods of production. Some of the methods include laser cutting, press brakes, spot welding, precision grinding, sheet metal fabrication, shearing, straightening and more. However, the most common methods of production are the precision metal stampings, CNC (computer numerical control) fabrications and assembling of the finished products.

One of the most widely known methods of manufacturing is the precision metal stamping. This process involves engraving lettering, three-dimensional parts and other surface definitions onto metal surfaces. The stamping works by using extreme pressure to force various forms and dies onto the metal materials. When the stamp is removed, the lettering, forms and dies are immutably engraved onto the metal. Stamping can be engraved on copper, aluminum, steel, titanium, alloys and numerous other types of metal. There are many types of equipment used in precision metal stamping varying from a simple manual press to a more engineered and computerized die processor. Some of the more engineered models can stamp with speeds up to an impressive 1,200 strokes every 60-seconds. The size of the equipment may be as large as 600 tons.

The CNC (computer numeric control) method of manufacturing refers to the use of a computer ?controller? which reads the instructions and actually drives the powered mechanical device. These CNC machines can cut curves as easily as straight lines. They can easily create 3-D structures and are more cost efficient than the older methods, because less machines (and humans) are necessary to complete the same products. With the ongoing investments in this method of manufacturing, consumers have seen improvements in both quality and consistency. Another benefit of using CNC is that a product can be produced in smaller quantities (to test the market) and then if production needs increase, the larger demands can be met using precision metal stamping.

The assembling component of precision metal component manufacturing involves completing the project. Each component is individually created using CNC, precision metal stamping or other methods of manufacturing. Then the assembling process is ready to begin. The on-site assembly saves the consumer both time and money (completing the entire project in one process/place).

There are many products assembled using precision metal component manufacturing. Simple items such as metal rings or clips can be created. Some of the more specialty items include appliances, kiosks, telecommunications and even medical supplies. Products produced using precision metal component manufacturing are all around us.

Metal Finishing and Vibratory Deburring

While at first glance vibratory deburring & metal finishing may seem somewhat a niche market it should be noted that every coin, window stay, button, knife, fork, spoon, turbine blade, hip joint or indeed an enormous range of mass produced metal, plastic and even (in some cases) wooden components are vibro finished.

The UK has been the home of vibratory deburring & metal finishing systems. These machines are also a standard solution for the manufacturing community internationally.

It is now common-place to find a vibratory deburring / metal finishing machine adjacent to laser cut, waterjet cut and CNC milling operations.

The benefits of being able to take stillages of sharp edged laser cut or waterjet cut, CNC milled components and make them clean, bright and ?handable?, at a consumable cost in the region of ?1 / ?2 per stillage, are numerous.

Vibratory finishing machines rarely breakdown and the uniformed results are easy to duplicate time after time.

With the latest machines coming complete with sealed for life bearings and the fabrications being stressed relieved these machines require nominal levels of maintenance.

Along with the traditional deburring of metal pressings and casting applications the latest consumables from the PDJ Vibro range of can now improve surfaces from 0.2 ra to 0.03 ra.

Given the above it is clear to see why the medical, motor sport and aerospace industries have depended on this process for decades.

How it works. The vibratory finishing machine consists of a process chamber (usually lined with a protective rubber or polyurethane) which is mounted on springs and on a base. The process chamber is most frequently circular with a centre plate on which the motor is mounted.

The motor is fitted with top and bottom weight segments that are off-set by 90 degrees. When the motor is running normally at 1500 rpm the process chamber vibrates.

Circular bowls. The vibration causes the media (abrasive / polishing chips) in the process chamber to move in a torroidal (corkscrew) action. This action causes the media to affect the surface of the components. Given the correct media, levels of water, chemical additive and time this process will produce results ranging from light deburring / edge breaking to radiusing, burnishing, super-finishing, descaling, degreasing and corrosion inhibition.

Circular bowl vibratory deburring & metal finishing machines were first introduced over 40 years ago and now represent the vast majority of sales as the design ensures part damage can be avoided and that a flap and screen can be operated to separate the component from the chips / media.

Vibratory troughs Due to the shape vibratory troughs remain the ideal solution for processing longer / larger components like turbine blades, curtain poles, cylinder blocks etc. Should large components be delicate, divider plates can create compartments giving separate chambers which completely eliminate the potential for part on part damage.

(Automatic unloading is not generally available with troughs and it should be noted that components tend to migrate to the ends of the chamber which can cause impingement).

PDJ Vibro Ltd are a Metal Finishing Company based in central England. Providing new and used vibratory finishing machines as well as consumables.

Orthopedic Manufacturing - Medical Manufacturing Miracles Performed On A Daily Basis

Many people, either due to birth defect, accidental injury, or simply old age, have joint conditions that cause loss of mobility. In advanced cases this can cause considerable pain and anguish. When doctors determine that the problem can only be remedied with orthopedic surgery, to augment or replace the affected joint, orthopedic manufacturing comes to the rescue.

Orthopedic manufacturers produce the supports and replacement joints that allow patients to return to normal life again. This procedure often is highly successful, but, of course, there are risks associated with any type of surgery.

The story of Jack Nicklaus, (a hip replacement patient) is a classic orthopedic case history. He lived with considerable pain for years, until he finally underwent hip surgery in 1999. Following his hip replacement he still managed to play some pretty good golf.

You may also be interested to know how those implants are made. The technology that allows doctors to perform the miracle of joint replacement is a testament to modern manufacturing ingenuity.

Orthopedic manufacturing has gone from science fiction to practical reality in the span of a few short years. Each year the techniques, tools, and products developed in orthopedics improve, by leaps and bounds. Orthopedic manufacturing has a important role in helping us to live healthier and happier lives.

Continuous research and development in the design and manufacture of orthopedic implants and instruments is needed. As the costs and risks of orthopedic procedures are reduced, the miracle of modern orthopedic medicine can be extended to more and more people who need this type of care, to dramatically improve their quality of life.

Orthopedic Manufacturing - Technical School Talent Is Readily Available - The Benefits Run Both Ways

Orthopedic manufacturers and other manufacturing firms would be wise not to ignore the talents of local technical high schools and colleges in their operations. Nearly every manufacturing firm regardless of size, will likely have a number of jobs that they might consider to subcontract to vendors. One source usually not considered for subcontracted work, is the pool of local technical high school and college students.

Many counties across the US have technical high schools and colleges that train students in a variety of fields from automotive to advanced manufacturing technology. Often these students have several years of experience in areas that can assist manufacturers located right in their own backyard.

What are the advantages of an internship to the manufacturer?

1) Internships are usually offered only to the best and the brightest students in their class, and usually only to seniors.

2) Students have years of experience writing term papers, so they are usually computer literate. Basic skills such as word processing computer skills are usually very good to excellent.

3) Most schools due to the extremely attractive discounts offered to educational institutions, have software that is up to date with the all the most recent releases. Technical students are usually tech savvy and are current with the latest computer software. (CAD and computer graphics are now even taught in some regular high schools)

4) Costs will be likely be minimum or very reasonable. Each manufacturer will have to consult with the career department of the local technical school, to find out the terms of their internships. In addition, a simple donation to the school in the form of a grant, or donations of new or used equipment may be tax deductible. Consultation with appropriate accountants or tax attorneys for specific advice in this area is advised.

What are some of the jobs that tech student can provide ? Everything from basic software training on CAD/CAM to graphics, desktop publishing, web design, word processing, to tasks related to any of the above areas, and others should be considered. It is also wise to rely on advice from the counselors and teachers at the school to find out what is appropriate.

A large degree of common sense is recommended here. Of course, students should never be given any task for which they have not been properly trained. Any specialized type of work or work that involves risk should be avoided under all circumstances. Safety is paramount here for all concerned. In general, office jobs are more appropriate than any kind of work on the shop or factory floor.

What expectation should a technical student have of their experience? Often the biggest obstacle students may find upon graduation is their lack of experience. Any industry experience at all is good, but an area that relates specifically to their major or career field is very beneficial. Every student looking for their first job faces a field in which there are not only other students with similar background, but other candidates, sometimes with years of experience.

An internship and a good recommendation from a reputable company, can separate a student from the rest of the field. It shows initiative and demonstrates aptitude for a particular field. They also may find that their experience gives them a better feel for their career choices in order to make wise decisions for their future.

Students can see what really does on in a manufacturing plant. For some, it may be the first time to set foot inside a manufacturing facility outside of the classroom. They may have preconceptions, especially negative stereotypes that can be dispelled, through their experience.

There are numerous benefits of manufacturing internships for the manufacturer and the student. Students can gain valuable real world experience, and manufacturers can gain fresh talent with up to date computer skills from some of the best young minds that may one day lead their industry.

Google Linking And The Principle of Mutual Benefit

Business on the Internet - Internet Linking Explained ? Based on Mutual Benefit - not as different from offline business as you may think.

There seems to be a certain mystique about technology today, especially about the Internet. I remember in the early 90's before I got on-line, I had read dozens of magazine articles on the Internet.

This was way before Google and even before AOL. I was led to believe that the Internet was some vast medium for entertainment, and it sounded similar to TV, except unlike TV, you could choose what to watch.

What I found when I finally got on-line, was that the Internet was not really about entertainment at all. It was more like a vast Electronic Library of information, except that unlike books, the electronic pages were "linked" together. I was fascinated that you could move instantly, (well not exactly, since I had a dial-up modem connection), from one page to another one, with a simple click of the mouse. We all take this for granted now, but as my daughter asks me, ?What was the world like before the Internet? ? It is so much a part of many of our lives that it is hard to imagine the world without it.

At the time, I wondered, why no one could tell me that the Internet was like a big electronic library, where web sites were like electronic magazines all linked together. It seemed so simple for me to explain once I experienced it, but everything I had read up until that point had fallen short, and failed to describe it adequately.

The same thing is true, it seems of business on the Internet these days. If someone knows how to market on the Internet, they are treated like a guru. Why is it so hard to find someone who will explain how to do business on the Internet in a clear and straightforward way, that every one can understand ?

Through this simple introductory article, I will try to demystify one essential Internet business strategy called Linking, or as defined by the most popular search engine on the planet, Google Linking.

It is important to remember that the vast majority of businesses in the US are still what I would call brick and mortar businesses. There is a building with a street address, that has overhead, and all that goes with it. If you have a ?brick and mortar business?, and you want to stay in business, and become successful, you need to provide a valuable product or service to your customers, and treat your customers well, regardless of the type of business you run.

Think of either businesses you have worked for in the past, (even your own), or places you like to visit to shop, or even companies you know where you would like to work, if you were given the chance.

If you want to just survive, you can do business as usual, without changing anything, (if you are lucky, that is), but if you want to grow your business, you must subscribe to the principle of "Mutual Benefit".

In other words, you must make your customers happy, and yourself happy at the same time. In fact, both parties must share equally in this mutual benefit. If you or your customer are happy when the other is not, the relationship will inevitably break down.

In addition if there is never any kind of personal relationship, as well as an offer of a good quality product or service at a reasonable price, there also may not be a long term relationship.

There is sort of a Law of the Universe at work here, and the Universal Law applies to an Internet business just as well as it does to a typical ?brick and mortar? business. The only real difference is that you may never actually meet your customers face to face. That is not to say that you can't have a personal relationship with them. They will just have to get to know you, and you will have to get to know them, through the medium of the Internet.

If you overcharge your customers, you will find them searching out your competitors. If you let your customers dictate your prices, or the level of service you provide to them, and let them take advantage of you, than you will not be happy about their return business.

Often, this seems like a delicate balancing act between you and your customers, but those who strike the right balance will have plenty of return customers year after year. If you are trying to get rich quick, just like in mainstream business, you are very likely to be sadly disappointed.

Think back to all the companies you worked for in the past. If you evaluate these business from the perspective of mutual benefit, you will discover something very interesting. First of all, those that merely survived and those that thrived will have either followed this principle closely or ignored it.

Also, those that followed the mutual benefit principle were enjoyable places to visit as a customer, or as an employee. Those that disregarded mutual benefit were likely distasteful places to work, or even worse, what I would call ?living nightmares?. What is good for my customer, and good for me in equal proportion, that is what determines long term success.

The same is true on the Internet. Don't ever think that you can cheat someone on the Internet. Sooner, or later, you will likely fall flat on your face, and be sadly disappointed at the outcome.

Think of all of the relationships you made with your customers as "links" to prosperity. The quality and quantity of these relationships are the measure of a healthy business. These relationships did not come easily, they had to be earned.

Internet Business, works the same way. Think of all of the electronic links to your site as friends of your business, even if they have never, and most likely will never purchase your product or service. Treat them all with respect as though they were your customers. The quantity and quality of these links will determine the type of page rank your site will have.

This is not easy, and in fact, involves some plain old hard work, in terms of as time and effort. If you pursue the appropriate keywords for your industry that have a reasonable amount of traffic, and get these keywords from another site ?linked? to your site, especially high quality sites with a good page rank, you will find yourself with plenty of quality traffic to your site that you will be able to convert into sales.

I am reminded of a book, by Ray Esquith called "There are no Shortcuts". He is a Disney Teacher of the year, and a well respected elementary school teacher in urban LA, who quite simply works harder at teaching than any one else, and his students produce superior results year after year.

There are web sites all over the Internet promising quick riches for little or no work. How many people actually made money in the Gold Rush, and how many just sweated it out ? There is simply no push button or lazy man's way to riches on the Internet, just as in mainstream business. Unfortunately, there are too many unscrupulous marketers on the Internet, who promise much and deliver little or nothing, to fools who are eager to part with their money.

If you want to earn a high page rank on Google, you can;t push a magic button, and you can't buy your way there, you have to earn it. Look at CNN.com for example. This web site has a page rank of 9 out of a possible 10. There are probably hundreds of people creating and editing content that changes on a moment to moment basis, on their web site. CNN.com had (at last check), over 180,000 web pages that link to it. Is it any wonder that their web site is so highly rated ?

Don't be scared and think that your small business has to become like CNN. The best and fastest way to get your site to the top of the search engines is, surprisingly to write a press release. Don't get scared off by this, it really is no big deal. You just have to become a miniaturized, small scale, cnn.com correspondent to begin your journey to success on the Internet. In the days before the Internet, you would not have any hope of this, but now thanks to the Internet you can become a mini cnn.com and be successful with a very small percentage of the success of CNN.com.

What your press release will do is create a back link to your web site that will rate very highly with Google. How do you start ? Begin by thinking like a tiny CNN correspondent. Is there anything that might be interesting or newsworthy about your business ? It doesn't need to be something that would featured in the newspaper or on TV.

This is mini-journalism, or micro journalism. It is the new medium called the World Wide Democratic Web, where even the little guy can get the attention he deserves. Find something interesting about your business, and sit down in front of the computer and write about it. This is not as traumatic as you might think. Keep it to the point. Keep it simple, choose only one topic at first, and try to make it interesting.

Don't forget to never use the first person, always write in the 3rd person in an objective and straightforward manner, stating fact and not opinion. Don't sell, tell, instead. Everyone on the Internet wants information. If you do not strictly observe this rule, your press release will not be accepted.

Make sure that you have done your research on Google, ("Google keywords" is a good place to begin). There are a number of sites to get good information on which keywords to select. Use Google and just type in whatever you want to find out. Keywords that are specific to your industry are the most valuable because they are the most relevant, even though they might not generate a great deal of traffic. Always be on the lookout for keywords that are relevant, and have substantial traffic.

It is better to be listed in the top 3 pages for a category that has 1 million references, then page 10 of a 50 million hit category. (Check the number of hits on the top right of the page on Google each time you do a Google search). Note: if you are trying to challenge a very large category such one with 50 million hits, you may need to employ additional linking strategies over and above what is mentioned in this article. It may even be wise to hire a Search Engine Professional to assist you. By the way, if you lay a good foundation for assistance by a "SEO Pro", by following these methods, you will have saved yourself a great deal of expense. You may also find an SEO Strategy company with very reasonable rates.

Write using these keywords several times in a short 250-300 word article, and submit your press release using one of the free press release sites on the Internet. Write as many press releases as you can over a 30 day period. 10 releases are good, 20 are even better. You can also send them out to several different press release sites. Read their guidelines for submission and learn their rules. Always make sure to put a link to your web site, in the correct section.

Try this for 30 days, and see what is does to your listing on Google ! You may be very pleasantly surprised.

Hot Melt Parts - Sandwich Recipe or Essential Consumer Technology?

Some of us may have used glue guns purchased at local art supply stores for art projects around the holidays. The same idea is behind the high tech glue guns that are used on automated assembly equipment that operates at production speeds. These precision special machines glue together all of the boxes we see in our local supermarket, and across the spectrum of consumer products. Hot melt technology is even used in the diapers we put on our children.

Every day glue guns deposit millions of little drops of glue on millions of boxes and other specialized products throughout the world. They hold together all of the "stuff" we buy that comes in cardboard and other type of boxes, even some types of plastic packaging. This is done totally automatically and it happens 24 hours a day 7 days a week.

This technology was essentially pioneered by the Nordson Corporation, beginning in 1954. Wherever products are labeled, sealed together, zipped, or shipped, chances are that Hot Melt Technology of one form or another is at work. The array of industries that use this technology is staggering: food and drink, medical, pharmaceutical, automotive, nonwoven, consumer appliances, metal machining and fabricating, and many others.

Some specific applications for hot melt dispensing equipment are bag forming and sealing, tray forming, case and carton sealing, labeling, pallet stabilization, corrugated box assembly, folded cartons, and myriad types of product assembly.

Glenmar Technology in Plainfield, NJ has developed replacement hot melt parts for a wide variety of applications. Their manufacturing expertise developed from years of experience in the contract machine shop business. They have a background of over 20 years in the production of everything from screw machine parts to high precision milled parts.

There are a number of challenges to producing replacement parts for this industry. The industry demands a high level of precision, since hot melt packaging equipment operates at very high speeds. The diversity of different applications is also a challenge, since each industry has it's specific application and unique requirements.

A company that produces hot melt replacement parts has to know the industry well, and produce parts very efficiently and cost effectively. Hot glue valves, hot glue guns, hot glue modules, hot glue hoses, and a wide variety of other parts that are essential to their customers must be offered.

Although the production of hot melt parts is a challenge, it is also a creative process since the industry is very dynamic. It evolves continuously to meet the challenges of an industry where speed, precision and flexibility are paramount.

How to Choose a CAD CAM System

The selection of a CAD/CAM system is an important one for any design or manufacturing company. It has ramifications all the way from the beginning of the product concept phase to the end of the manufacturing process. It is likely that, only a single CAD or CAM vendor will be chosen, (although multiple stations may be procured). For most companies, a CAD/CAM software purchase decision is a one-time event. Because of this fact most companies have somewhat limited experience in the purchase of a CAD CAM system. A reliable CAD CAM consulting firm can be an important ally in the process of system selection.

This review will consider five important criteria. These criteria are listed in order of importance. Most companies place a great emphasis on initial cost and the list of features / benefits first. In this recommendation, ease of use is listed first.

1)Ease of use - productivity

2)Vendor stability and longevity

3)Features ? functionality

4)Cost ? total cost of system

5)Maintenance / upgrade and training costs

1) Ease of use

In practical terms, the ease of use of the system will have the most significant return on investment. It is often forgotten that design or manufacturing personnel may spend anywhere from 100 ? 2000 hours per year on the system. (Estimate based on 2 hours part time per week, or 40 hours per week on a full-time basis.) The average cost of this labor is many times greater than the cost of the CAD CAM system itself. Even a 10 % reduction in time spent to complete a particular task could have a savings of over $ 5,000.00 in labor costs, the first year alone ! This is more than the entry price of most CAD systems !

Note: This estimate is based on use of the system on a full-time basis with a conservative calculation of a $ 25.00 / hour labor rate. Ease of use as it relates to productivity, is the single most important criteria to evaluate, and yet it is also the most difficult of the criteria to quantify.

Benchmarks: some companies attempt a timed benchmark between various systems, to evaluate this measure of productivity. This is problematic, however, since these types of competitive benchmarks are just as easily influenced by the individual skills of the CAD or CAM engineer, as they are by the software system itself.

It is wise to ask the vendor to demonstrate the creation of a particular part that is similar to others that you have designed or manufactured in the past. It is much easier for you to compare systems on a part that you are already familiar with than a ?canned? demo on a part the vendor chooses.

2)Vendor stability

Make sure that the company chosen has a stable financial base, and has been in the industry for at least 10 years. One of the worst things that can happen to CAD/CAM customers is to lose the support and upgrade path for their software, because their CAD/CAM software vendor has gone out of business. This leaves customers stranded, and eventually their software will become relatively obsolete.

3) Features and functionality

Many prospective CAD/CAM customers try to calculate the value of their software based on a long list of features, and try to compare to other systems. The difficult of this is that the terminology used to describe certain functions varies from system to system. Vendors may also unintentionally or intentionally obfuscate this point, by claiming unique functionality which is really just a question of semantics.

For most customers, the CAD/CAM software industry is sufficiently mature to have more than enough functionality to satisfy even demanding customers. If your job requirements are highly specialized, or unique to your industry, then you may need to carefully examine specific functionality to make sure the software you choose can meet your needs. In terms of CAD software, this might be libraries of standard components particular to your industry, or it could be a unique type of warpage calculation, etc. For CAM systems, pay particular attention to specialized turning machines that are not simple 2-axis plus C-axis milling. Screw machines, multiple turrets or rotary turrets on a lathe, can be problematic. For milling machines, 4-axis and 5-axis applications can be very tricky to evaluate and can present special challenges for the machine tool manufacturer, and software vendor.

Again, a CAD/CAM consultant can be invaluable to scope out specialized requirements, and assure the the software meets the specific intended application.

4) Cost

This is the easiest criteria to evaluate, but one caveat emptor needs to be addressed. Most CAD/CAM software is sold on a modular basis. No company should purchase more CAD/CAM modules than they need. There should always be an upgrade path open for a later purchase of additional modules if needs expand or change. Buyers also take note that this industry is extremely competitive, and in general customers really do get what they pay for. Prices are stable and well established, and there really are no fire sales, or steep discounts available. One further note: it is usually wise not to purchase software that has been licensed to another company, without expressed written consent from the software vendor. Many software purchase agreements prohibit transfer of a particular license from one company to another, (unless the software has been transferred as a result of a company buyout or merger.

5) Maintenance, Upgrades, and training and support

Users should not be shocked to find that software is regularly upgraded, at additional cost. This is true across the entire software industry. Since CAD/CAM Software is generally more costly than other type of software, is should also be no surprise that software upgrades are also more expensive than other types of software. Upgrades should be available on a regular basis. It is good to ask what the time period was between the last several upgrades. Most CAD/CAM software should have an major upgrade every 12-18 months. Users should not be penalized for failure to upgrade. They may find, however, that reasonable restrictions may be placed on support for badly outdated software.

Support hours should be reasonable, and at cover business hours, with some consideration to start and finish times within the time zones. Training costs should not be exorbitant. Group training for several employees at one time, or on-site training may also be available.

The use of good buying common sense and informed decision making using the above criteria can make the difference between a smooth CAD/CAM installation and something less than desirable.

Exclusive Leads - SEO Strategy - VoIP Web Conference - Keys to Industrial Sales

The development of exclusive leads based on a well though out SEO Strategy using VOIP Web Conference technology are keys to success in promoting industrial products over the Internet.

It has been claimed that any successful Internet Marketing campaign must find a consistent way to refine or qualify leads in order to find interested prospects that can become customers. When manufacturers market on the Internet, it would be wise for them to borrow a page from the successful Internet Marketers handbook.

Many Internet sites are set-up as a simple ?squeeze? page or what is essentially a push-button method transform prospects into customers. Successful and ethical Internet marketers realize that the eye-ball grabbing method is not always the magic formula to gain long term repeat customers for industrial products. The most successful SEO strategy is to consistently pursue numerous avenues for leads, over a period of time, and follow a proven system to develop exclusive leads from a large pool of potential prospects.

Regardless of the lead generation used to generate traffic to a given web site, attention must be paid to the overall SEO Strategy. The key to Internet promotion is closely tied to the search for information. There are so many ways to market a a company or particular products over the Internet, but in everything is it wise to consider an SEO Strategy based on keywords. This is the method that will allow Internet users to find the information that they are looking for that will link back to the company's web site.

Any site or traffic portal can be used for this purpose. Any marketing system that can develop ?exclusive leads? that come to their members' mailbox only, can be used. It is highly recommended not to buy or rent e-mail lists. It is also critical to use a double opt-in verification system for any e-mail sent over the Internet. Even when a prospect fills out a contact form on your site, that submission must be validated. Without a confirmation e-mail there is no way to determine if the information is legitimate or not. This is the gold standard for e-mail marketing that will gain credibility, and avoid e-mail complaint problems and complications.

Another new and highly successful technology that is gaining great momentum on the Internet is VoIP Web Conference technology. This technology is on the leading edge of a trend that will eventually transform the way business is done on the Internet. There are numerous advantages to the use of this technology. Sales presentations can be done on-line in real-time. Voice, Power point style presentations, even video on demand can all be offered on the same site. Direct customer service, training, and many other possibilities exist for the use of this technology.

Laser Machining

Laser machining technology uses high intensity laser beams of varying widths for a variety of applications such as slotting, cutting, and creating holes. It can be used in fabrication of different types of materials such as metals, plastics, vinyl, glass, marble, and graphite. Other materials that can be fabricated using laser machining include nylon, ceramics, carbon fiber, composites, soft rubber, and thin metal foils.

Laser machining systems are used in conjunction with computer numeric control (CNC), which makes it ideal for use with thin walled tubing, boasting beam widths down to .0005'. In this process, the machining operator uses computers to control machine tools for manufacturing complex and intricate parts in metal and other materials.

A laser machining process involves the use of conventional as well as fiber optic beam delivery systems, which allow precision positioning while cutting metal or other materials. It is used to cut burr-free parts that are required in a number of industries such as aerospace, automobile, shipping, and others. The process is fast, efficient, and can be repeated any number of times depending on production volumes. It is used to create grooves that are cut to a specific depth with one pass of a laser beam without severing any material from the work piece.

Laser machining is used for producing a knurled or roughened surface on hard materials such as metals and fragile materials such as ceramics and glass. The technology is also used for marking material surfaces. In the process a high intensity laser beam is passed through a stencil of a mirror and onto the area of the material or work piece that is being marked.

Research is underway to develop advanced laser machining techniques that will allow the production of microscopic devices for use in medical industry. This will help in fighting deadly diseases such as cancer in the near future.

Machining Jobs

Machining refers to the basic process of cutting parts out of a work piece according to predetermined size and shape. Machining jobs are performed using different types of machining techniques such as laser machining, wire electrical discharge machining (EDM), Chemical etching machining, metal stamping machining, water jet machining, and abrasive water jet machining.

Most of the machining jobs are controlled with the help of computer numeric control (CNC) software that guides the cutting equipment along the lines and arcs of a computer aided design (CAD) drawing. The CAD drawing is a three dimensional (3D) graphic representation of parts that are to be fabricated.

Apart from cutting parts from work pieces, machining jobs also include the process of "grinding." Grinding is a process in which a grinding belt or wheel is rubbed against the work piece for removing unwanted material from it. The process is commonly used for fabricating metal pieces that are too hard to be machined by other machining processes. The work piece does not heat up during this process as water is used to cool it. "Drilling" is another machining job, which involves the use of a drill or a drill press that has a drill bit for cutting parts from a work piece.

Machining jobs may include "milling," wherein the milling machine resembles a drill press and the cutter looks like a drill bit that goes downwards in the piece to be cut. However, the milling process is less accurate and is preferred less than the turning or grinding machining process.

Machining jobs have enabled manufacturers to design and produce complicated parts used in high tech industries such as aerospace and automobile. An increasing number of machining jobs are now being rendered using environmentally friendly techniques, such as water jet and laser, which are good for the future growth and development of manufacturing industries.

Machining Techniques

Machining refers to the industrial process of cutting and fabricating metals and other materials into predetermined shapes and sizes. Machining process is controlled with the help of computer numeric control (CNC) software that guides the cutting equipment along the lines and arcs of a computer aided design (CAD) drawing.

A machining process may involve the use of different techniques depending on the number of parts being manufactured and the type of material. Machining techniques may include manual machining, which is used for cutting metal sheets in simple shapes such as circular, square, and rectangular. This process is however being replaced by automatic machining systems and processes that can cut any type of shape out of metal sheets needed for different purposes.

Chemical etching machining technique is mainly used for producing typical precision parts. The machining system offers a great flexibility for producing precision parts with unusual configuration as well as metals with tight tolerance within .0005'. Besides this, chemical etching machining is capable of producing small holes and bars that are not possible with other machining techniques. Another common process is Wire Electrical-Discharge Machining (EDM) in which the metal is separated from a conductive work piece by means of electrical erosion. During this process, the wire never touches the conductive work piece and leaves a path on the work piece, which is slightly larger than the wire.

Another technique known as the metal stamping machining phenomenon, which is also referred to as progressive die stamping or long run metal stamping, is extensively used in production of precision parts with thickness from .002' to .135'. The technique is mainly used for processing typical low price parts that are formed into three dimensions.

Apart from these, some modern techniques are also in use such as abrasive water jet and laser machining that are more accurate and environment friendly as compared to conventional machining techniques.

Automotive Machining

Machining techniques are used widely in the automotive industry for manufacturing different automobile components such as outer body sheets, internal components, and windscreens. Automobiles are produced in an assembly line that requires the same type of components for producing them in large volumes. Different components are prefabricated using machining processes and transferred to the assembly line for final production.

One of the most common automotive machining techniques in use today is known as wire electrical discharge machining (EDM). Wire electric discharge machining (EDM) uses a wire electrode that travels through the conductive work piece. The electrically charged wire is monitored by a Computer Numerically Controlled system (CNC).

Wire EDM removes a material from the work piece by spark erosion. During this process, the wire never touches the conductive work piece. The electrically charged wire leaves a path on the work piece, which is slightly larger than the wire. Often a 0.010' wire is used which creates a 0.013' to 0.014' gap. The wire electrode can just be passed once through the conductive work piece, and cannot be reused.

The gap between the wire and the work piece generates high voltage electrical pulses. The high voltage and the controlled spark melt and vaporize a small part of the work piece. Each spark produces a temperature of 10,000? C, where as the energy turned out by the power supply decides the size of the spark penetration into the material. With the improvement in the cutting speed, reliability, unattended operation, and accuracy, it is also becoming popular in many other industries such as the aerospace, defense, and electronics.

The multiple work pieces set up and unattended operation saves a lot of time of the operator, which can be fruitfully utilized on other job functions. The wire EDM system is very cost-effective and can be operated at around $4 per hour in normal cutting conditions.

Stainless Steel Machining

Stainless steel machining refers to the process of cutting steel sheets or bars into predetermined shapes for use as components in various industries such as aerospace, automotive, shipping, and others. Stainless steel machining can be done either manually or with the help of automatic machining systems combined with computer aided design (CAD) software.

Manual machining is used for cutting stainless steel sheets in simple shapes such as circular, square, and rectangular. This process is however being replaced by automatic machining systems and processes that can cut any type of shape out of metal sheets needed for different purposes.

The most commonly used technology used for stainless steel machining is known as Computer Numerical Control or CNC machining. The technology is mainly used to cut intricate shapes and designs into hard metals such as stainless steel, which otherwise are difficult to form, mold, or manipulate. In this process, the machining operator uses computers to control machine tools for manufacturing complex and intricate parts in metal and other materials. Moreover, the cutting process is enabled using a software program written in a notation confirming to the EIA-274-D standard, which is often referred to as G-code.

Another common process is Wire Electrical-Discharge Machining (EDM), in which the metal is separated from a conductive work piece by means of electrical erosion. During this process, the wire never touches the conductive work piece and leaves a path on the work piece, which is slightly larger than the wire.

The technology has dramatically reduced human intervention and enabled machining processes wherein curves are as easy to cut as straight lines and structuring intricate 3-D parts has become relatively easy to produce. Stainless steel machining has greatly helped in increasing automation of manufacturing sector, and has enabled remarkable improvements in consistent and quality production. It has also helped in reducing the frequency of errors and workload of machining operators.

Machining Quotes

The number of firms offering machining services has increased over the years, which can confuse a client wanting to avail of machining services. Machining firms often take care of this problem by quoting their machining rates on the Internet or via toll free phone lines.

Machining quotes are available for different types of machining techniques such as laser machining, wire electrical discharge machining (EDM), Chemical etching machining, metal stamping machining, water jet machining, and abrasive water jet machining. Quotes are also available for machining different types of materials such as metal, wood, ceramics, carbon fiber, marble, cardboard, soft rubber, plastic, composites, and others.

Machining quotes available on Internet websites are generated with the help of database software that contains detailed information about various machining techniques and their prices according to the type of material being machined. Users just need to select the type of machining and the number of parts required. The software processes this input according to predetermined parameters for generating machining quotes. This allows users to gather information about machining rates offered by different firms and helps them in selecting the firm that offers the most cost effective rates. After getting the customer's approval, quotes are converted into sale orders and the machining process starts after receiving the requisite amount from the customer.

Water Jet Machining

Water jet machining technology involves the use of high-pressure water jets for cutting parts out of different types of material such as soft rubber, foam, extremely thin stuff such as foil, carpet, paper, cardboard, soft gasket material, candy bars, diapers, and soft wood. Its use is limited, as it cannot cut harder materials such as metals, glass, and hard wood.

The water used in water jet machining systems is pressurized between twenty and sixty thousand pounds per square inch (PSI) depending on the type of material being cut. The highly pressurized water is released through a tiny hole called "jewel" which is typically 0.007" to 0.015" in diameter, creating a very high velocity beam of water capable of cutting soft materials.

Water jet machining process is controlled with the help of computer numeric control (CNC) software that guides the water jet nozzle according to the lines and arcs of a computer aided design (CAD) drawing. The CAD drawing is a three dimensional (3D) graphic representation of parts that are to be fabricated. The technology has many advantages such as easy to use components, quick assembly process, reduced turn around time on the machine, complementariness to other machining techniques, and cutting without heating the material.

One major drawback of water jet machining is that the nozzle often gets blocked due to dust particles that might be present in the water. The other problem with water jet assemblies is that they are prone to constant wear and tear caused due to high-pressure water flowing out of tiny nozzles.

These drawbacks are however ignored, as water jets are the most environment friendly and safe machining technology used in the present era. It does not produce fine particles that might get into the human body and cause fatal diseases such as cancer. Particles if any are swept away with the strong force of the water jet and do not pollute the surrounding environment.

Wood Machining

Wood machining refers to the process of converting wooden logs into planks, fabricating them into desired shapes and sizes, and polishing them for use in the final product. Wood machining has acquired great importance in recent years due to the short supply of wood and increasing environmental awareness among users and manufacturers. Wood machining techniques that are in use, stress on the maximum utilization of wooden logs and help in reducing wastage.

Wood can be technically defined as a hygroscopic, orthotropic, biological, and permeable composite material having extreme chemical diversity and physical complexity with structures, that vary extensively in their shape, size, properties and function. All this makes it very difficult to develop a standard machining technique applicable to all types of wood as their response may differ when subjected to a machining process.

Commonly used wood machining processes involve the use of electric powered vertical chain saws or rotary saws that cut wood in the required shape and size. Water is used on a regular basis to cool down the chain saw as well as the wood for allowing smooth and uninterrupted cutting operations. Wooden planks produced during this process are still very rough and cannot be used in manufacturing the final product.

The next step involves the use of sand paper strips mounted on circular rotating disks. Wooden planks are passed under these to give them the required finishing needed for manufacturing the final product. Automatic presses can also be used for bending wooden planks in the required shape or drilling holes in pre-designated places according to product design.

The woodwork industry follows different strategies for achieving optimized wood machining process keeping in mind the mechanism and principles of deformation, crack initiation, and propagation of different types of wood. Other factors are also taken into consideration such as humidity, temperature, static preloads, and vibrations that can affect the wood during machining process.

How To Buy A Press Brake

When looking for a press brake, or brake press, you need to know what type of press you are looking for. Press brakes come in all sizes and with many different options. You can buy a brake press that is hydraulic, mechanical, air clutch, air trip, and of course CNC or computer numerical controled.

You need to first know your Capacity, which is rated by tonnage. Then you need to know the legnth and distance between housings. The distance between housings is usually smaller than the capacity of the machine. If you are looking to bend 10' and need to go past the gap, you will need a 12' brake.

As for the clutch, Hydraulic clutch is the safest, and most expensive. They are generally slower and have more of a precise bend.

Air clutch machine work in the same way except they use air to activeat the clutch. The difference is that you have to complete the rotation once activated. This makes it more dangerous, but faster.

Air Trip, is a cheaper, sometimes aftermarket clutch system that can be added to a standard mechanical brake press.

Mechanical is the most dangerous of them all, you lose alot of control. The clutch has to make a full rotation, and can't be stopped at any time during the process.

CNC press brakes are the latest in manufacturing. They can have mutiple axis Backgauges, and you can program them to do different bends. This is the most expensive and the best for production.

That should give you a basic rundown on how to purchase a press brake.

Sterling Machinery Has been in business for over 55 years and are proud to help educate buyers on purchasing your press brake.
