PROBLEM TO BE SOLVED: To control with high accuracy a polishing load for pressing a rotating polishing tool to work. SOLUTION: In the polishing device in which the polishing tool 1 is abutted on the workpiece to perform polishing working, a second member 4 for generating magnetic suction force in a radial direction is suitable for a first member 3 mounted to a tool shaft 2 of the polishing tool 1 and the second member 4 is rotated to rotate/drive the polishing tool 1. By moving the second member 4 in a thrust direction by a motor 12, the polishing load for pressing the polishing tool 1 to the workpiece is given. The polishing load is not influenced by the rotational number and rotation torque of the polishing tool 1. COPYRIGHT: (C)2011,JPO&INPIT |
