PROBLEM TO BE SOLVED: To apply wire electric discharge process on a plurality of workpieces simultaneously even under an electric discharge processing condition where a pulse rate is high.SOLUTION: A wire electric discharge processing system that slices a workpiece by electric discharge processing with a distance of wires arranged side by side, includes: a workpiece feeding unit for sending a plurality of workpieces arranged in different positions in a travelling direction of the wires arranged side by side, in a direction approaching to the wires arranged side by side; a power supply unit for supplying pulse voltage to the wires arranged side by side; and a pulse voltage control unit for applying individual pulse voltages of which application times of pulse voltage for electric discharge processing on the plurality of workpieces are not overlapped, to each of the plurality of workpieces.SELECTED DRAWING: Figure 2 |
