PURPOSE:To permit the wire to be automatically and readily supplied even after the wire electrode is disconnected abnormally or cut in order to move to the following process by constituting a automatic wire feeder for a wire cut type electric discharge machining device so that the wire electrode can be automatically cut and removed as well as resupplied. CONSTITUTION:A workpiece 10, which previously has start holes 12 and 14 vertically penetrating at given positions, is mounted on the mounting table which can be freely controlled and moved on a horizontal plane according to the X-Y coordinates crossing each other at right agles. Between the bent parts at the upper and lower ends of an electrode guide 16, a screw shaft 18 is provided rotatably. Moreover, a wire electrode 60 is passed through a pipe 48 and set so that the lower end of the electrode 60 is lower than a clamping plate 50. Said constitution permits the wire to be automatically and readily supplied even after the electrode 60 is disconnected abnormally or cut in order to move to the following process. |
