摘要： In a wire electric discharge machine (1) in which chuck part electrodes (20) that hold a wire electrode (1) are provided on the upper side of an upper wire guide (24) and electrodes (22) of a detecting part are provided on a lower stream side of the chuck part electrodes (20), a part, which contacts with the chuck part electrodes, of a surface of the wire electrode is hardened by locally cooling down the part by air blowing during energization to the wire electrode. Accordingly, wire metal powder is hardly generated from the wire electrode even though the wire electrode rubs against the chuck part electrodes.

A wire electric discharge machine comprises an annealing/fusing device that anneals and fuses the wire by heating the wire with a current supplied to the wire, whereby linearity is provided to a wire by annealing and a semi-spherical configuration is provided to a wire leading end by fusion, thereby making it possible for a wire to easily be introduced into the machining groove at the wire connecting position.

摘要： A plurality of sections (Q00-Q11) are set on a wire path in order to detect and record positions where blocking of wire connection failure and disconnection failure occur at the time of wire connection in a wire electrical discharge machine. At the time of wire connection, a counting value in a position pulse counter of an encoder is cleared in a state that the wire has been fed to a feeding starting position (Po). Feeding of the wire is continued while deflection of the wire is detected by a ring-shaped electrode disposed on a wire path. When the wire is blocked, a position where a connection failure occurs is found from a position pulse counting value in the encoder, and is stored on a set section basis. When a disconnection failure occurs, a position pulse counting value is cleared at the time of occurrence of the disconnection, and a position where the connection failure occurs is found from a counting value at a point of time when the wire is wound up to a position (Po), and is stored by on a set section basis.

摘要： A device for automatic connection of the wire electrode in a wire cut spark machine, which is capable of conducting automatic connection of the wire electrode smoothly and reliably. A wire processing unit (90) integrally and rotatably coupled to a rotary shaft (61) of a pneumatic pressure motor (60) has a nozzle-forming unit (120) which, when it is opened, forms a slit (S) that permits a wire electrode (W) to pass through and which, when it is closed, forms a nozzle hole (125) that can fit to an upper wire guide (12). The wire processing unit (90) is selectively located by means of a stopper (150) at either a wire inserting position or a wire retreat position. In case the wire electrode is broken, the wire processing unit is driven by a motor from the retreat position to the wire inserting position. Then, the nozzle-forming unit is closed, so that the wire electrode introduced through the slit when the wire processing unit is driven is held in the nozzle hole. Thereafter, as a working liquid is supplied from the upper wire guide to the nozzle hole, the wire electrode is fed and automatically connected, being confined by the working liquid injected onto the work (P).

摘要： This invention provides an automatic wire connecting method in a wire cut electric discharge machine by which a wire electrode can be inserted into a machining start hole having an extremely small diameter with a simple structure. An upper wire support part (17) is moved together with a wire, until the tip of the cut wire (1) goes into a machining start hole (7, 7'), towards a workpiece (6) aligned with the wire support portion (17) disposed on the wire supply side of a wire feeding system. Then, while the wire tip is kept inside the hole, the upper wire support portion is moved away from the workpiece and then the wire is trans- ported to a wire take-out side of the wire feed- ing system to complete connection.
