CNC Electrical Discharge Machines (EDM)
An Electrical Discharge Machine (EDM) works similarly to plasma cutters by using an electrical arc to remove material at the required location. This method can create fast 2D cuts on metal sheet format.
Applications of CNC Electrical Discharge Machines include: Manufacturing Injection Molds, Die Casting, Blanking Punches and Prototyping. A CNC electrical discharge machine works only for conductive materials. You cannot use this method for machining plastics, ceramics, wood, or other non-conductive material.
