PROBLEM TO BE SOLVED: To extremely increase polishing removed amount and allow short time polishing by partially filling polishing media into inner space of a hollow body, rotating the hollow body itself, and revolving the hollow body around a revolution axis spaced from a rotation axis of the hollow body in the direction opposite to the rotation direction. SOLUTION: A rotation mechanism of a hollow body 8 is loaded on a rotational table 7. The inner space of the hollow body 8 is filled with polishing media 9. The longitudinal both ends of the hollow body 8 are journalled to a bearing via sleeves. By adding rotation force from a motor via a bearing for transmitting power in the rotation mechanism, the hollow body 8 is rotated around a rotation axis. Rotation of the motor 5 rotates a revolution axis 1, the rotational 7 is largely rotated around the revolution axis 1, the hollow body 8 is revolved around the revolution axis 1 oppositely to the rotation direction, and thereby the inner surface of the hollow body 8 is physically polished. |
