To provide a method of mirror-polishing a complicated shape body, in which fluid polishing is implemented in a manner being out of contact with a polishing object, without generating stress over the entire area of the object immersed in polishing solution even if the polishing object has a complicated shape with bumps and dips, to thereby finish the polishing object with a mirror surface, and to provide a mirror-polishing device.
According to the mirror-polishing method, magnetic field generating sources 7 for generating magnetic fields are arranged on a peripheral surface and an external bottom surface of a flow bath 2, and the magnetic polishing solution 1 is charged in the flow bath, followed by hanging a specimen 3 (polishing object) from a support portion 6 to be immersed in the solution. The magnetic polishing solution 1 is mixed with nonmagnetic abrasive grains and α-cellulose as a thickening agent. Then the specimen 3 is rotated by a driving motor 5 linked to the support portion 6, and the flow bath 2 is suitably oscillated by an oscillation stand 8 linked thereto, to thereby agitate the polishing solution in the bath. In this manner the specimen 3 is immersed in the magnetic polishing solution 1 over the overall area except for a mounted surface, and the magnetic field is exerted on the overall surface, followed by pressing the abrasive grains by magnetic clusters generated in the polishing solution, to thereby carry out polishing by relative movement of the abrasive grains.
