Title:
WIRE ELECTRIC DISCHARGE MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/127103
Kind Code:
A1
Abstract:
A wire electric discharge machine (10) for machining a workpiece (W) by generating an electrical discharge by a wire electrode (60), comprises: an upper wire guide (64); a roller (78) that feeds the wire electrode; a pipe (110) through which the wire electrode is inserted and a refrigerant flows; a positive electrode (132) and a negative electrode (134) that contact the wire electrode between the pipe and the upper wire guide in a state in which the positive electrode and the negative electrode are spaced apart from each other in the feeding direction of the wire electrode; and a power supply (140) that applies a cutting voltage between the positive electrode and the negative electrode when cutting the wire electrode.
