EDM machines generate high-frequency electrical sparks between an electrically conductive workpiece and the machine’s tool-electrode, usually made of copper, brass, or tungsten, to remove material from the workpiece and obtain finishes impossible to achieve by traditional machining processes. Primarily used to machine hard metals and alloys such as Titanium, Kovar, and Inconel, CNC EDM machines use digitized data to shape workpieces into the desired shape at an unrivaled level of precision. Whether you need a die-sink or a wire-cut EDM machine, Surplus Record is your one-stop shop for all your EDM needs! Check out our 186 listings of CNC Electrical Discharge Machines today!
