EDM

Electrical discharge machining (EDM), also known as spark machining, spark eroding, burning, die sinking, wire burning or wire erosion, is a manufacturing process whereby a desired shape is obtained by using electrical discharges (sparks).

Sinker Electric Discharge Machining, our specialty, is a process composed of an electrode and workpiece submerged in an insulating liquid. In this process, the electrode and workpiece are connected to a power supply, generating an electrical aptitude between the two components. As the electrode nears the workpiece, an insulating breakdown occurs in the fluid, forming sparks. These sparks occur simultaneously, in vast quantities, eroding the base metal… Continue reading to learn more about our process.
