WIRE EDM PROCESS

A process called “WEDM” or “wire electrical discharge machining” enables manufacturers to machine complex parts from materials which often do not permit machining using other techniques. For example, this process (also called “wire cutting” or “wire cut EDM”) allows cutting to help contour hard components, such as diamond, carbide and graphite.

Wire EDM machining typically involves the use of a narrow single strand of wire in conjunction with de-ionized water. As controlled electrical impulses flow through the wire, it produces sparks as it cuts contours in the surface of hard materials. The water flowing over the area cools the part and prevents melting, while also helping clean away tiny fragments of cut metal from the work surface.
