PURPOSE:To prevent a machining solution in wire cut electrospark machining from scattering about and to feed the enough quantity of a machining solution to part to be machined, by forming a liquid flowing curtain around the machining solution that is being fed from a nozzle to the part to be machined. CONSTITUTION:A machining solution 6 is fed from a nozzle 5 along a wire electrode 1 toward the machining gap between the wire 1 and the work 3. From the nozzle 7 arranged concentrically around the nozzle 5, the low speed liquid is flowed so that it surrounds the jet machining solution 6 to for the liquid flowing curtain 8 that prevents the jet machining solution 6 from scattering about, and the jet pressure of the machining solution is increased to perform effective electrospark machining. |
