ABSTRACT:
A wire electrical feeding device for an electrical discharge machine. Vibrator assemblies are utilized to feed the wire electrode through electrode guides of the electrical discharge machine. A first vibrator assembly vibrates through a locus which includes a component in the wire feeding direction. The wire electrode is selectively pressed against the first vibrator assembly when the first vibrator assembly is moving in a direction having a component in a wire feeding direction. In the alternative, a second vibrator assembly, which is coupled to the first, clamps the wire electrode when the first vibrator assembly is moving in a direction having a component in the wire feeding direction. The vibrator assembles may each be driven at different vibrational frequencies.
