WIRE ELECTRIC DISCHARGE MACHINING SYSTEM AND PROCESSING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To adjust a processing current value to a suitable value using resistance (impedance) by length of wire when multiple wire is fed processing voltage collectively for electric discharge machining.SOLUTION: A wire electric discharge machining system comprises: travelling means by which the wire electric discharge machining system slicing work at intervals of juxtaposed wire makes the wire travel for juxtaposition; a feeding die feeding processing voltage collectively for the multiple wire among the wire travelling for juxtaposition; a discharge unit in which the processing voltage fed to the multiple wire discharges between the work and the multiple wire; and adjustment means adjusting impedance with the multiple wire placed from the discharge unit to the feeding die at an optional value so that the feeding die travels the position to feed the multiple wire.
