Electrical discharge machining

Electrical discharge machining (EDM), also known as spark machining, spark eroding, die sinking, wire burning or wire erosion, is a metal fabrication process whereby a desired shape is obtained by using electrical discharges (sparks).[1] Material is removed from the work piece by a series of rapidly recurring current discharges between two

How to Achieve Efficiency in Graphite Electrode Milling

The demand continues to grow for high speed machining centers used in the milling of graphite electrodes for die-sinking EDM. For awhile, it seemed like the advancements in the machining of hardened steel might make graphite electrodes obsolete; however, there are factors that continue to make electrodes, and thus high-speed machining, a critical process for moldmaking.
