CNC Wire EDM is electrical discharge machining. This machine works around electrical discharges, electrical “sparking” actions and electrically conducting materials. The CNC Wire EDM machines offer ultra high tolerances and precision that no other CNC machine can match. If you need that specific part designed that is an exact fit to within microns, the CNC Wire EDM machine will get it closer to perfect than any other CNC machine.
Most of the time CNC Wire EDM machines are kept in positive air flow rooms that are temperature controlled. The machines are more like clean rooms than an actual machine shop. The environment that these machines work in help to push the machine beyond the manufacturer’s intended limits and the operators can squeeze even more precision out of it.
Computer numerical controlled technology has definitely become a driving force in the machining industry. The machines that have been developed from the use of this technology, in combination with robotic technology, make the sky the limit in the machining industry. No other CNC machine can prove this like the CNC Wire EDM machine.
The technology involved in the CNC Wire EDM machine is comparable to that of a band saw; however, unlike the band saw, there is no “blade” in this machine. This machine cuts with a coiled piece of brass wire that can be as small as 0.002″ in diameter. There is never any pressure on the wire or on the material being cut: actually the wire never comes into contact with the material. The cutting comes because of a sparking action that occurs in the gap between the wire and the material. This all means that you will no longer have to use clamps to hold your materials into place. The use of “crazy” glue is all that it takes.
With the CNC Wire EDM machines, exacting tolerances that would be hard to manufacturer in any other case is actually possible. With this machine, there are no cutting “tools” that get wore out, so the machines capability of producing multiple product at the same exact tolerances are very possible and easy to produce.
It takes extremely skilled CNC machinists to operate these machines to the high standards that have been described. Attending a CNC machining school will only teach you the basics of CNC machining; however, you can learn this type of precise machining with experience. On the job learning can be done. It may take a while to achieve, but in the end, it will be worth it.
If you have any further questions about the CNC Wire EDM machining process or on the machines themselves, then contact your dealer or supplier. They will be able to further assist you by answering any questions that you may have. Detailed descriptions and explanations can be given upon request. If anything, the dealer will help you to determine the type of machine that you need for your business and can help point you in the right direction.
