Sinker EDM

Electrical discharge machining (EDM) is a novel machining method that is used in industries such as aerospace, because of its ability to handle materials that are unusually robust. EDM has evolved into wire EDM, EDM small hole drilling, and sinker EDM. Sinker EDM uses an electrode die negative, which is slowly rammed into a workpiece, carving out a depression in the shape of the die. Parts with complex geometries, clean surface finishes, and small tolerances can be created in this way, for all conductive materials.
