This product is an electrical spark wire cutter machine. The machine is ideal equipment for machining dies in machine building, electronics, aviation, and petrochemical and household electric appliance industries. It is able to machine varieties of complicated and precision dies, cam, templet and parts, and is suitable for cutting all kinds of nonferrous metal, carbon steel, hardened steel, hard alloy and semiconductor materials. Wire electrode processing technique is adopted, so that workpiece is only under a little pressure, little in deformation, high in machining precision, good in roughness, high in cutting speed and low in energy consumption.
