First Claim
Patent Images
1. A method of ultrasonically grinding a workpiece, comprising the steps of:
- immersing a workpiece and an electrode as an anode and a cathode, respectively, in an electrolytic processing solution, the electrolytic solution being contained in an ultrasonic processing tank equipped with an ultrasonic vibrator;
applying a voltage between said workpiece and said electrode;
simultaneously radiating ultrasonic energy from said ultrasonic vibrator into said electrolytic solution to electrolytically grind surfaces of the workpiece;
drawing the electrolytic solution from said ultrasonic processing tank;
cooling the electrolytic solution to a temperature lower than a boiling point thereof;
deaerating the electrolytic solution; and
thereafter circulating and returning the electrolytic solution to said ultrasonic processing tank.

Abstract
A workpiece to be ground is immersed in a processing solution with abrasive grains suspended therein. The processing solution is contained in an ultrasonic processing tank equipped with an ultrasonic vibrator. Ultrasonic energy is radiated from said ultrasonic vibrator into said processing solution to ground surfaces of the workpiece. The processing solution is drawn from the ultrasonic processing tank, cooled to a temperature lower than a boiling point thereof, deaerated, and then returned to the ultrasonic processing tank.
