The principle of electrical discharge machining is simply a thermal processing method that converts electrical energy into heat energy of the work piece to quickly melt the work piece.

Industrial manufacturing requires machining tolerances. EDM machine can cut metal through electric current.

There are some differences between the general EDM machine and wire-cut electrical discharge machining. Different processing technologies are applied to different industrial manufacturing needs.

Spark erosion machine is a type of EMD machine. It is precision-machined by releasing current. It is an industrial manufacturing process.

Before getting to know EDM machine, start with understanding the type of EDM machine, including wire EDM, sinker EDM, and hole drilling EDM, and perform metal cutting through electrical discharge machining.
