The principle of electrical pulse machining, like WEDM, is to use WEDM to corrode conductive materials, while WEDM can only process all kinds of straight and curved parts. Parts of the same type or different shapes.

Electrical pulse can be used to process molds and parts with complex cavities and cavity shapes; Permeable or impenetrable parts, processing all kinds of hard and brittle materials, such as cemented carbide and hardened steel; Machining deep fine holes, special-shaped holes, deep grooves and narrow seams.
