DISCHARGE LIQUID EJECTOR OF WIRE CUT TYPE ELECTRIC SPARK MACHINE

摘要

PURPOSE:To make it possible to eject discharge liquid uniformly on a work and to improve the working efficiency of an ejector at the time of wire connection by a method wherein a notch 11 is provided in the disk-like injector so that the discharge liquid is ejected from the circumference of a wire electrode. CONSTITUTION:An ejector 10 is provided with a notch 11 and an ejecting port 13' in the disk-like top end thereof. Further, the ejector 10 is so arranged that a wire 2 passes through the notch 11 in the vertical direction between a work 3 and wire guides 5. The discharge liquid is supplied by a pressure supply pipe 14 and ejected toward a section to be machined with the electric spark from the ejection port 13'.
