  • Wire-cut electric discharge machine in which two adjoining segments of a common electrode effect machining
    Patent number: 4803326
    Abstract: An apparatus in which a wire electrode is pulled off a supply reel, passes through a predetermined path, is led to the machining portion of a work piece to cut the work piece, there-after, the wire electrode is turned back, is returned along the path it has come to the machining portion of the work piece, and is used again to work the same work piece. At least one of these two segments of the wire electrode is advanced in a zig-zag path along the machining line when the work piece is cut, thereby allowing the working gap to be widened for improving the efficiency and accuracy of machining.
