Title:
WIRE ELECTRIC DISCHARGE MACHINE
Document Type and Number:
WIPO Patent Application WO/1994/023881
Kind Code:
A1
Abstract:
Between first and second wire cutting electrodes (13, 14), a wire feed pipe structure (12) which consists of a cooling fluid introduction member (29), an elongated pipe type annealing member (30), a fluid discharge member (31) and a heating member (32) arranged in the mentioned order from the upper side, and which has a through bore (33) in the central portions of these members, is provided so that the axes of these through bores are aligned with that of a wire passage. The cooling water is supplied from the cooling fluid introduction member (29), passed through the annealing member (30) and discharged from the fluid discharge member (31), and it is not sent to the heating member (32). Consequently, the wire is cut necessarily in the heating member, and receives an annealing effect in the annealing member (30).
