Geometrically similar to hobbing, copper and graphite electrodes are “sunk” into soft or hardened conductive materials such as punches, cavities, and bearing races. Unlike the wire EDM process, machining does not have to go completely through the work piece, and unlike conventional milling, little force is exerted on the parts or electrodes. This allows for extremely delicate shapes, holes, and finishes, on parts before, or after, heat treatment. Electrodes Today’s technology offers a wide variety of electrode materials containing graphite, tungsten, copper and silver, in the various combinations necessary for optimum “burn” conditions, in various conductive materials. Most of these conditions are pre-defined by the technology in the machine itself. For more info visit our website at
