PURPOSE:To rotate a spindle efficiently with no noise by coupling the rotor in a drive section for rotating a tool lathe with respect to a fixed base with the spindle secured to the tool lathe, and securing the stator in the drive section to the base. CONSTITUTION:The rotor in a drive section coupled directly with a spindle 2 secured to a tool lathe 1 is rotated by means of the stator in the drive section secured to a base 3 around the spindle 2. The tool lathe 1 is rotated stably with no noise through rotation of the rotor 30, and a ring 8 is driven through rotation of the tool lathe 1 so that a sample stuck to a plate jig inserted into the ring 8 is polished through polishing agent to be fed onto the tool lathe 1 rotating relatively. |
