PURPOSE:To efficiently manufacture a large wheel having the fine luminosity by installing a controller for shifting a rotary buff in synchronization with the revolution of a rotary table according to the shape and state on the surface of the wheel. CONSTITUTION:A wheel 5 is horizontally set in a concentric state to a turntable 3 on the turntable 3. Then, a rotary buff 9 is installed in a vertically shiftable manner and tilt shiftable manner in the longitudinal and lateral directions on a shaft 24 arranged in the radial direction of the turntable 3. In this state, the wheel 5 is revolved, and polishing work is carried out by the rotary buff 9. In this case, servomotors 8 and 13, cylinder, etc., are driven in synchronization with the revolution of the turntable 3 according to the shape and state of the surface of the wheel 5 by a controller, and the polishing force of the rotary buff 9 is kept always constant by properly shifting the rotary buff 9 in the X-axis, Y-axis, and Z-axis directions. |
