Abstract
A polishing machine of the present invention is capable of uniformly polishing a member to be polished with high flatness, and polishing cloth, which is employed in the polishing machine, is uniformly abraded. In the polishing machine, a polishing plate is capable of rotating. A supporting table rotatably supports the polishing plate. A rotary driving mechanism is mounted on the supporting table, and it rotates the polishing plate. A base supports the supporting table. An orbital driving mechanism moves the supporting table along a circular orbit without spinning about its own axis.
