摘要： A wire-extension end detector having high operational reliability is provided for use with a wire-cut electric discharge machine. As a wire comes between a wire drive roller and a pinch roller during a wire extension, it is conveyed by rotation of the rollers. As the wire travels, a disc (4c) integral with a tension brake roller driven by the running wire is rotated. A signal processing circuit (24) receives and delivers a pulse train output from a photoelectric switch (5) in accordance with a black-and-white code pattern on a rotating disc coupled thereto, and generates an H-level output indicative of the end of wire extension. If the wire extension fails, an H-level output from the signal process circuit is not output and a wire extension is carried out again.

摘要： An upper guide assembly for a wire cut electric discharge machine adapted to be mounted with an automatic wire feeding mechanism, which holds the wire without direct mechanical contact. A hold jet nozzle is connected to the upper portion of a body 23, while an upper guide is connected to the lower portion of the body. The body includes an electrode roller for supplying electric power to the wire, and an electrode pinch roller capable of coming into and out of contact with the electrode roller. The hold jet nozzle includes a through hole whose center axis is aligned with a wire path a provided in the upper guide assembly and extending vertically, and a supply passage for pressurized machining fluid communicating with the through hole. The upper guide contains a die guide and an upper nozzle. A guide axis of the die guide and a center axis of the upper nozzle are aligned with the wire path a. During operation of the wire cut electric discharge machine, pressurized machining fluid is supplied to the supply passage to form a water pillar, which produces an urging force in the upper guide assembly, whereby the wire is guided through the upper guide assembly by the water pillar without contacting with interior parts of the assembly.
