PURPOSE:To prevent a grind burning generated by the unfit grinding accompanied by the elastic deformation of the body to be worked by the support force of the clamper device operation time and to eliminate the strength reduction by the grind burning of the body to be worked by quickly returning a grindstone when a clamper device is actuated. CONSTITUTION:A sequencor 1 storing the sequence program concerning a grindstone feeding to the internal part and generating a control command and a servomotor 3 controlling the feeding of the grindstone of a cylindrical grinder by receiving the command of the sequencor 1 are provided. Then, when the clamp device of the cylindrical grinder is operated, the servomotor 3 is driven by this sequence program and the grindstone is quickly returned. Thus, the grind burning generated by unfit grinding accompanied by the elastic deformation of the body to be worked by the support force of the clamp device operation time can be prevented. |
