Abstract
A mechanism capable of decreasing wires which are not appropriately supplied with power and performing the electrical discharge machining high in uniformity between multiple wires. A wire electrical discharge machining system configured to slice a workpiece at an interval of wires arranged side by side at equally spaced intervals causes the wire to travel in the same direction and includes a power feed contact configured to collectively supply a machining power supply to a plurality of the traveling wires, in which two adjacent power feed contacts respectively come into contact with the plurality of the wires supplied with the machining power supply and arranged without being aligned in the direction vertical to the direction in which the wire travels.

Abstract
A multi-wire electrical discharge machining system for slicing a workpiece into a thin leaf at intervals of a plurality of wires arranged together causes the wires arranged together to travel in the same direction and includes a power feed contact configured to collectively comes into contact with the traveling wires, a machining power supply portion configured to supply a machining power supply to the power feed contact, and an electrical discharge portion configured to electrically discharge a machining power supply in which the traveling wires comes into contact with the power feed contact to collectively supply power to the traveling wires to the workpiece, in which a resistance between the machining power supply portion and the power feed contact is smaller than a resistance between the power feed contact and the electrical discharge portion.
