Electrical discharge machining

Electrical discharge machining, also known as electrospark cutting, is a precision technology in which CNC machines use tiny electrical discharges to machine materials. These discharges are generated between the workpiece and the electrode, which in this case is a wire cutter. This is equipped with a wire made of copper, molybdenum or coated wire with a high zinc content.

This method enables any electrically conductive material to be precisely machined and cut to the desired shape and size. EDM is most commonly used in the production of forming and injection moulding dies, as well as cutting and pressing tools for the mass production of plastic, glass or metal parts. This technology can process workpieces weighing up to 500 kg using wire with a thickness of 0.1-0.3 mm.
