Electrical discharge machining (EDM) is a special type of machine tool that uses the principle of electrical discharge machining to process conductive materials. It is also known as electro-erosion machining. EDM is mainly used for machining various high-hardness materials (such as hard alloys and hardened steel) and complex-shaped molds and parts, as well as for cutting, grooving, and removing broken tools (such as drill bits and taps) from workpiece holes.

Electrical Discharge Machining (EDM) Machine ToolIt is a machine tool device that uses the principle of electrical discharge to erode the surface of metal parts. Since the principle of electrical discharge machining is different from that of ordinary metal cutting, the structure of the EDM machine tool differs from that of ordinary metal cutting machine tools. First, it has a high-energy pulse power supply device to provide energy for generating electrical sparks, mainly functioning to produce repeated high-intensity electrical pulses on the tool electrode and workpiece electrode to generate discharge sparks; secondly, because there is no direct contact between the tool and the workpiece during electrical discharge machining, and there is no significant cutting force, the EDM machine tool does not require a high-strength main drive system. However, to ensure a discharge gap of a few micrometers to hundreds of micrometers between the electrodes, it employs a highly sensitive automatic gap adjustment device that can automatically measure and adjust the gap at any time.
