Abstract
A sleeve and a hub are fixed to each other, and then the sleeve and the hub are gripped and rotated around a central axis, during which cutting is performed over the inner peripheral surface of the sleeve and a flange surface of the hub. Thus, the flange surface can be finished accurately such that the flange surface is normal to the central axis and the inner peripheral surface of the sleeve.
