PURPOSE:To prevent the machining liquid from escaping to the machined groove side and improve the effect of the removal of chips, cooling of a wire, etc. by inserting a bar-like body in to the machined groove nearly in parallel with a wire electrode and at a slight distance apart from the wire. CONSTITUTION:A wire electrode 2 machines a work 3 to form a machined groove 3B. A bar-like body 40 is held by holders 26, 27, which are rotatably supported by the wire electrode 2 serving as the center. In addition, the holders 26, 27 are driven by rotation drive mechanisms constituted with motors 36, 37, worms 34B, 35B, and gears 34A, 35A respectively and are controlled in response to the proceeding direction of the wire electrode 2 so that the bar-like body 40 is invariably positioned in the machined groove 3B. |
