ABSTRACT:
The subject invention relates to an electroerosion machine which utilizes a plurality of moving wires for cutting a metal workpiece by means of an electrical discharge between each of the wires and the workpiece. The machine includes a frame, and a table is mounted on the frame for carrying the workpiece. The machine also includes an electrical system. Each of the wires of the plurality of moving wires is an electrically conductive wire which is wound on a respective supply spool. Each of the wires from a respective spool is connected to a tension assembly. The wires are then directed from the tension assembly to a cutting guide assembly. At the cutting guide assembly, the wires are positioned proximate to the workpiece and there is an electrical discharge between the wires and the workpiece to erode the workpiece. A take-up assembly takes the wires from the cutting guide assembly for storage of the wires.
