PURPOSE:To allow treating liquid to be spouted concentrically with a wire electrode for improving the machining efficiency, by constructing a nozzle such that the pressure of the treating liquid is once moderated and that the flow of the liquid is prevented from reduction. CONSTITUTION:A guide support body 6' is provided with through holes 11 for passing treating liquid there through, and a nozzle 8' is fixed to the support body 6' with screws. The treating liquid is once received by a horizontal plane and then spouted outside from an injection nozzle 12 concentrically with the wire electrode 1. Since the treating liquid 7, after passing through the holes 11, once hits against the horizontal plane within the nozzle 8', all the treating liquid is directed toward the injection nozzle. Thus, the treating liquid can be injected from the nozzle concentrically with the electrode 1. |
