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

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

Why do we need a drilling machine? The drilling machine can perform precise drilling without damaging the object so that a drilling machine is an indispensable processing technology in industrial manufacturing.

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.
