ABSTRACT:
The automatic cutting and re-threading mechanism for the electroerosion machine employs a baffle which moves into and out of alignment with the direction of the wire so as to route the unwanted waste wire from the electroerosion machine into a waste bin. In order to cut the wire, the wire is gripped between a feeder roller and a drawer roller at which point it is both heated and stretched prior to being cut. Two power supplies are employed, one power supply to heat the wire using electrodes which make contact with the feeder roller and the drawer roller and a second power supply which is used to heat the electrodes that cut the wire.
