Claims

[Scope of utility model registration request]

A rotating conductive grinding tool, a rectifying member in which conductive parts having different conductivities are arranged alternately on a circumferential surface and rotates integrally with the grinding tool in a state of conduction with the grinding tool, and the grinding tool an electrode body disposed with a space between the machined surface of the grinding tool, a DC power source that applies a direct current so that the rectifying member serves as an anode and the electrode body serves as a cathode, and a machined surface of the grinding tool. and coolant supply means for supplying a weakly electrical coolant between the electrode body and the electrode body.
