Abstract
A brake is provided for a workpiece spindle for spindle control. The generation of position shear of a workpiece spindle due to the unbalanced contact of the brake is prevented by changing the clamping power before and after the contact with the workpiece spindle. After the clamping of the workpiece spindle, the servo controlling state of the workpiece spindle motor is maintained and the overheat of the motor is prevented by limiting the torque of the workpiece spindle motor.
