    摘要: An upper guide assembly (41a) includes an upper wire guide (43a), an upper power feed contact (44a), and a power feed contact movement device (45), and a lower guide assembly (41b) includes a lower power feed contact (44b). The upper power feed contact and the lower power feed contact contact the wire electrode (2) to supply power by moving in a horizontal direction from initial positions (Al, A2) not contacting the wire electrode. The power feed contact movement device moves the upper power feed contact in the horizontal direction from the initial position by a predetermined offset amount (dl). The offset amount is set based on a machining condition including at least one of a condition of the wire electrode, a condition of a workpiece (W), and a surface roughness required for a cut surface of the workpiece.

    摘要: The present disclosure relates to a waste wire recovery apparatus, which includes: a waste wire recovery unit recovering a waste wire discharged from a wire electric discharge machine while rotating; and a rotational actuator rotating the waste wire recovery unit. Since the waste wire recovery unit rotates when recovering a waste wire, the waste wire can be uniformly received in the waste wire recovery unit. Accordingly, the stack density of the waste wire received in the waste wire recovery unit is improved, so the amount of a waste wire that can be transported at one time on a vehicle, etc. can be increased. Accordingly, the economic efficiency of reusing a waste wire can be improved.

    摘要: In a fixing structure and fixing method of a wire bobbin (24), the wire bobbin (24) is abutted against a regulating member (62) with a bolt (64) inserted into an insertion hole (24c) of the wire bobbin (24). Then, a nut (70) is brought close to the wire bobbin (24) while the bolt (64) is inserted into an obliquely formed through hole (72) and the nut (70) is kept inclined so that the axis of the through hole (72) is substantially aligned with the axis of the bolt (64). Thereafter, the inclination of the nut (70) is returned so that the axis of threaded hole (68) becomes substantially aligned with the axis of the bolt (64), and then the nut (70) is turned so as to insert part of a tapered portion (74) into the insertion hole (24c).
