PURPOSE:To polish and wash the surface of an object to be treated irrespectively of whether said object has electrical conductivity or not by putting the object into an electrolytic mixing region consisting of medium fluid and abrasive grains and applying ultrasonic oscillation and electromagnetic field thereto. CONSTITUTION:An electrolyte 6 used generally as medium fluid is put into an electrolytic cell 1 and an electrode bar 2 is disposed at the center. An ultrasonic oscillator 4 is attached to the lower part of the cell 1. Abrasive grains 7 such as diamond powder are charged into the electrolyte 6 to form an electrolytic mixing region 8. A electrically conductive or non-conductive object 9 to be treated such as metal, ceramics, glass or the like is put into such region 8. DC, AC pulsating current or pulse current is passed from a power source 3 to the electrode 2 at the same instant and the oscillator 4 is oscillated at 10-50kHz frequency. The object 9 is polished and washed by the friction effect of the grains 7, the electrolytic effect of the cell 1 and the bar 2 and the electric discharge effect generated in the surface of the object to be treated.
