EDM FAQs

Our Wire EDM machining tolerances are as low as ±0.0004 (0.01 mm).

Wire EDM is mainly used for processing all kinds of workpieces with complex shapes and fine precision. For example,Wire EDM can process the convex die, concave die, convex-concave die, fixed plate, unloading plate, forming tool, sample plate, fine holes and grooves, narrow slits, arbitrary curves and so on.

Wire EDM machining requires that the processed material be electrically conductive and it is not possible to machine non-metallic conductive materials. Additionally, Slow efficiency and limited cut size affect the production of large volume production.
