Electrical Discharge - Machining

Between sparks, the dielectric fluid flushes away the eroded particles (debris) to prevent short circuits and prepare the gap for the next discharge. Main Types of EDM Electrical Discharge Machining (EDM) - Beltim & Associates

A power supply creates high-frequency electrical pulses across a tiny gap (0.005 mm to 1 mm) between a tool electrode and the workpiece. Electrical discharge machining

The process occurs within a —typically hydrocarbon oil or deionized water—which acts as both an electrical insulator and a coolant. Between sparks, the dielectric fluid flushes away the
