PURPOSE:To sufficiently supply working liquid between electrodes, even if a wire electrode is tilted, by installing a nozzle in turnable ways, having a wire guiding- hole arrangement part formed inside the body having a hollow part for introducing working liquid, as center, and allowing the supplied liquid to flow along the wire electrode. CONSTITUTION:A nozzle 2 which is supported in slidable ways at one edge part of a cylindrical body 1 and performs spherical movement and a wire guiding pipe 5 are installed, and each one edge part of the inside case 6 and the outside case 7 of the body 1 is formed into spherical form. When a wire electrode 9 in a cut groove is worked, tilted with respect to the body 1, the nozzle 2 which is formed integrally with the guide pipe 5 turns, following to the tilt of the wire electrode 9, and the coaxial relation between the electrode 9 and the nozzle 2 is always maintained, and therefore, the working liquid supplied from the nozzle 2 is supplied along the electrode 9, even if the electrode 9 is tilted in any direction, and the working liquid can be supplied sufficiently between the electrodes in the cut groove. |
