ABSTRACT:
An untrasonic machining method which comprises applying an electric current across a workpiece and a tool subject to ultrasonic vibration and ultrasonically vibrating the tool, while supplying an electrolyte to the gap between the workpiece and the tool, said workpiece and tool being positioned a certain distance apart, said electrolyte containing spherical soft abrasive grains suspending therein, said ultrasonic vibration actuating said abrasive grains so that they remove the film formed on the work surface of the workpiece by electrolysis, with the removed film being discharged from said gap during machining. Alternatively, the electrolyte and abrasive grains are supplied separately and mixed in the gap.
