Claims

[Claim for Utility Model Registration] A connecting hole with a magnetic body and/or a T-groove is provided so that the bottom surface can be fixed on the base of a reciprocating grinder, and a support base with a circular hole in the center is arranged. A motor consisting of a stator and a rotor formed thinner than the stator is inserted into the circular hole, a shaft and a plate are integrated into the rotor, and an outer frame is attached to the lower side of the outer periphery. A cross roller bearing that suppresses vertical and horizontal vibrations in the gap between the outer frame and the support base, in which a vertical rotating plate is connected, a rotating table made of magnets is connected to the rotating plate, and the outer frame and the support base are provided with a rotating table. A rotational motion auxiliary device for a surface grinder, characterized in that the motor is provided with a control circuit that maintains a constant circumferential speed as the workpiece rotates.
