EDM

Moldmakers rely on electrical discharge machining (EDM) routinely. EDM refers to wire, sinker and small-hole EDM. Sinker includes an electrode and a workpiece both submerged in dielectric fluid; wire uses a thin wire to cut with electricity; and, with small hole an electrode is a cylinder used to machine a hole. Considerations for EDM efficiency include depth, accuracy and finish, and components to consider include drives, generator, programming system and flushing. Other facets include wires, electrodes, graphite, filters and fluids.
