PURPOSE:To increase the machining speed and improve the working efficiency by supplying fine hard particles to the machining gap as well as applying vibration to the wire electrode. CONSTITUTION:Machining pulses are supplied from a machining power source 12 to the machining gap where an electrode wire 1 and a workpiece 7 face to each other, and pulse discharges are repeated to perform machining. A relative feed is provided to the workpiece 7 so that it is machined into the previously programmed configuration. The mixture of water and fine hard particles is supplied through a nozzle 14. In addition, a high-frequency vibration such as an ultrasonic wave and the like is applied to the wire electrode 1 by a vibrator 13. The vibration permits the effect of removing erosion products, gas bubbles and the like to improve. |
