Abstract

PURPOSE:To provide simply a finished surface having extremely good surface roughness by purifying working water in a working liquid tank to provide a high resistivity condition in a finishing stage and supplying said water directly to a electric discharge machining gap. CONSTITUTION:Before finishing, a wire cut discharge machine 2 supplies water working liquid 4 from a working liquid tank 3 and a pump 13 to a discharge machining gap G through a change-over valve 16, path 17, change-over valve 18, a supply pipe 5 and water guide 7 for discharge machining of a workpiece 6. In finishing stage, respective change-over valves 16, 18 are changed over according to the signal SW of a control unit 12 to send working liquid 4 forcibly sent by the pump 13 to a water purifier 19 so that about 100X10<4>OMEGA.cm of high resistivity water is provided by a filter 21 and ion exchanger 22 and supplied directly to said gap G through the supply pipe 5. Thus, a finished surface having extremely good surface roughness can be simply provided.
