PROBLEM TO BE SOLVED: To enhance process tolerance of a work piece in electrical discharge machining for slicing the work piece by use of multiple wires.SOLUTION: A multiple wire electrical discharge machine, with which a work piece is sliced at intervals of parallel multiple wire electrodes by electrical discharge, comprises a plurality of main guide rollers which drive the multiple wire electrodes in a same direction, and a pair of sub-guide rollers on the surface of which grooves are arranged at equal intervals. The pair of sub-guide rollers are located on both sides of the work piece, and are rotated as the multiple wire electrodes driven in the same direction contact the grooves. |
