Electrical Discharge Machining (EDM) Frequently Asked Questions

During the electrical discharge machining process, a workpiece is submerged in a dielectric fluid. An electrode is then used to produce an electric spark between itself and the workpiece, melting localised areas of the workpiece through thermal energy. This process happens hundreds of thousands of times per second, breaking down the workpiece to produce a desired shape.

Electrical discharge machining occurs through methods such as wire EDM, die sinking EDM, and hole drilling EDM.
