! The work in which the vibration J11 in the surface area comes into contact with either the left or right grinding wheel r1 as necessary to correct the unbalanced part by interposing the lI element is performed by using the grinding wheel with the tl1 grain surface and the grinding wheel with the dense grain surface. The reason is that it is configured to allow efficient and thorough grinding. Further, according to the present invention, the selection of the grinding surface of the grindstone and the rotation speed of the grindstone are controlled by the trimming control cycle vf
This can be done automatically by detecting the vibration frequency of the vibrator by S.
