Claim Text:
1. A multi-wire electrical discharge machining system for slicing a workpiece into a thin leaf at intervals of a plurality of wires arranged together, the multi-wire electrical discharge machining system comprising: a multi-wire electrical discharge machining apparatus including a plurality of main rollers configured to cause the plurality of wires arranged together to travel in the same direction and a power feed contact configured to collectively come into contact with the plurality of wires, wherein a machine power supply collectively supplying power to the plurality of wires having been collectively in contact with the power feed contact discharges at an inter-electrode between the workpiece and the plurality of wires; and a power supply device configured to supply the machining power supply to the power feed contact, wherein a resistance between the power supply device and the power feed contact is less than a resistance between the power feed contact and the electrical discharge portion.
