ABSTRACT:
A wire cutting type electrical discharge machining system for removing metal by utilizing of an electrical discharge energy between an electrically conductive workpiece and a wire electrode which is continuously fed lengthwise relative to the workpiece, including a frame, a wire guide conduit, and a flexible tube inserted in the wire guide conduit. The wire guide conduit is disposed fixedly with respect to the frame, so that the wire electrode is passed through the conduit. The flexible tube is axially slidably moved in the wire guide conduit in a telescopic fashion such that an outer end of the flexible tube is movable outwardly away from a corresponding end of the wire guide conduit, to an access position at which one end of the wire electrode may be easily inserted into the flexible tube through the outer end thereof and guided by the flexible tube into the wire guide conduit.
