PURPOSE:To lessen a danger to an operator and improve polishing efficiency by driving and rotating an abrasive of cylindrical shape and repeating mechanically the operation wherein the rotating abrasive accesses a workpiece, is pressed thereto and then moved away therefrom. CONSTITUTION:Each movable part of a polishing tool support mechanism is actuated whenever necessary while an abrasive is being turned with a motor 4, thereby making the abrasive 16 access in a direction opposite to a polishing surface 54. Concurrently, when a blower has been started, the abrasive 16 comes in contact with the polishing surface 54, thereby carrying out a polishing process. The dusts of a film removed with the polishing process are blown toward the suction opening 64 of a suction hood 62 and sucked into said opening 64 together with air on a suction force due to the operation of the blower. The abrasive 16 is moved in an arrow 'Q' direction by the polishing tool support mechanism and the polishing process continues. Also, the dusts as sucked are collected and clean air is discharged from the outlet of the blower. |
