1. The basic principle of wire cutting wire cutting copper wire molybdenum wire through the guide wheel group, and then by the guide wheel into the machine on the machine nozzle guide hole, and then into the lower nozzle of the guide hole. By these composition of a processing of a cycle of links, processing time through the upper nozzle connected to the wire energized, discharged high-voltage power supply through the copper wire flow to the lower wire guide nozzle connected to the wire, forming a discharge cycle loop, the use of this circuit on the workpiece for electrolysis processing. In the process of processing due to high-voltage current contact with the workpiece to produce instantaneous high temperature to corrode the surface of the workpiece, the use of corrosion traces accumulated by the way of processing the workpiece.
