PURPOSE:To make it possible to continue automatically the electrospark cutting work using the existing machine, by performing the cutting works on the part left uncut on workpieces after completing the electrospark cutting works to the last process. CONSTITUTION:When the cutting work is done on the plural number of cutting/ separating part of a single workpiece by means of the wire cut type electrospark machining method, the wire electrode 10 is automatically fed to the first hole 300 using the wire electrode feed unit 30a, 30b. The using the wire electrode automatic cut-off unit the wire electrode 10 is automatically cut with the part 308 left uncut. Then again the electrode 10 is automatically fed to the next hole 302 of the cutting/ separating part to be worked on, and the similar discharge cutting work is done with the part 312 left uncut. Thus, making use of the existing machine, the continuous cutting work can be automatically carried on to the next cutting/separating part 314. |
