摘要:
A wire electrical discharge machine (10) having an auto wire feeding function includes: guide parts arranged on a wire feed path along which the wire electrode (12) is fed so as to guide the feeding of the wire electrode (12); fluid paths (FP) formed with the guide parts to supply a compressed fluid to the wire feed path; a compressed fluid supply device (16) to supply the compressed fluid to the fluid paths (FP); a tension detector (34) to detect the tension of the wire electrode (12); and a control device (18) that controls the compressed fluid supply device (16) so as to supply the compressed fluid to the fluid paths (FP), and based on the detection result from the tension detector (34), determines whether or not the wire electrode (12) has reached a supply position (SP) of one of the fluid paths (FP) on the wire feed path to which the fluid has been supplied.
