PROBLEM TO BE SOLVED: To perform eccentric center adjustment for a workpiece to the axis of rotation without worker's skill and long-time set-up. SOLUTION: A cylindrical part 11 of a workpiece 1 sucked and held on a sucking surface 6 of a spindle to be movable in the eccentric direction is incorporated with a detecting part 8 so that a probe 8a is exposed to a working part 4 of an eccentric center adjusting device 3, and while the eccentric amount of the cylindrical part 11 is measured by the probe 8a, the cylindrical part 11 is pressed by the working part 4 to perform centering so that eccentric center of the workpiece 1 to the spindle can be eliminated.
