PURPOSE:To stabilize the discharging condition between a work and a wire electrode while to cool the wire electrode by providing means for inclining nozzle for ejecting working liquid along the wire electrode in two perpendicularly crossing directions. CONSTITUTION:A working liquid ejection nozzle 14 can be inclined in perpendicular direction against X-axis around a supporting point P or substantial fulcrum by means of a control motor 22 while in perpendicular direction against Y-axis around the supporting point P or substantial fulcrum by means of a motor 23. Since the nozzle 14 can be inclined with correspondence to the inclined angle of the wire electrode 5, the working liquid can be ejected at any time along the travel direction of wire electrode 5. While a guide tube 25 is provided with working liquid flow-in hole 27... and a portion of working liquid to be led through working liquid lead-in port 24 and a flow-in port 27 into the guide tube 25 will improve the cooling effect of wire electrode 5. |
