Document Type and Number:
WIPO Patent Application WO/1986/001445
Kind Code:
A1
Abstract:
A wire cutting discharge processing machine, in which a workpiece (W) is discharge-processed by an electrode wire (18) moving between upper and lower wire guides having a cooling liquid supply passage (62). This machine is provided with a throttle valve (68), which is set in a flow passage (66) branching from a main electrode wire-cooling flow passage (64) communicated with the cooling liquid supply passage (62), and which is adapted to regulate the cross-sectional area of the flow passage in accordance with the pressure of the cooling liquid flowing from the cooling liquid supply passage (62) thereinto. The cooling liquid passed through the throttle valve (68) is distributed around an electrode pin (42) in the wire guides to cool the same.
