Abstract
An eccentricity adjusting motor (83) is provided in eccentricity adjusting device (17) that adjusts an eccentricity in a work. A tilt adjusting motor (86) is also provided in tilt adjusting device (18) that adjusts a tilt of the work. A processor (2) computes the eccentricity and tilt of the work, based on which eccentricity/tilt compensating means (105, 106) control the motors (83, 86) to compensate the eccentricity and tilt of the work.
