PURPOSE:To perform the angle polishing of a silicone chip easily and precisely with no personal difference or irregularity by rotating the holding jig of the silicone chip via the magnetic field generated by a rotary magnetic field unit. CONSTITUTION:The magnetic field generated by a rotary magnetic field unit provided in a main body 10 is rotated in the fixed direction around the polishing surface 11 on the main body 10 by the action of a rotary contact 26 driven by a motor 25. A magnet 13 fitted to a holding jig 8 coupled and held by the main body 10 is absorbed and rotated by this magnetic field, and a silicone chip 7 stuck to the slant surface 9 under this holding jig 8 is pressed to the polishing surface 11 and polished. The lubricating liquid dropped from containers 2, 3 in a cover 1 screwed and fitted to the upper end of the main body 10 to the upper surface of the holding jig 8 and silicone powder are stirred and mixed and fed to the lower surface of the holding jig 8 through the penetrating hole 22 of the holding jig 8, and the silicone chip 7 is polished on the polishing surface 11. |
