Electric discharge machining fluid

Abstract

Abstract PURPOSE:To improve a machining speed without causing the wearing of an electrode, by using a nonion surface-active agent of w/o type adding 0.2-15% water into electric discharge machining oil. CONSTITUTION:Electric discharge machining liquid emulsified by nonion surface- active agent of w/o type adding water in 0.2%-15% proportion to electric discharge machining oil is used. In this case, the water and the surface-active agent are added to electric discharge machining oil and emulsified liquid can be obtained by using an ultrasonic stirring device. The machining liquid obtained in such way, in which the amount of water is suppressed to within 0.2-2% to fully perform stirring by an ultrasonic wave, can be formed to almost about transparent condition. Accordingly, during the machining, a machined part can be visually seen by the worker, in addition surface roughness is decreased while a machining speed can be increased without causing the wearing of an electrode.
