  • Patent number: 5357072
    Abstract: Consolidating expended electrode wire by cutting it into predetermined lengths facilitating handling and yielding a salable byproduct rather than mere salvageable scrap. The apparatus is adapted for use in a wirecut EDM machine having an advancing electrode wire, a wire driver assembly for advancing the electrode wire, and a roller assembly for drawing the expended electrode wire from the machine. For cutting the expended wire into predetermined lengths, a wire shearing assembly having at least one shear tip movable along a predetermined locus is provided. The wire shearing assembly is actuable by a drive assembly to move the shear tip at a rate effective to cut the expended wire into predetermined lengths. A guide bushing having a guide opening extending therethrough is interposed between the roller assembly of the EDM machine and the wire shearing assembly to receive the expended wire from the roller assembly and to locate it within the locus for shearing impact with the shear tip.
