- a through hole 15a may be provided in the peripheral portion 11y so that air is ejected from between the polishing sheets 14.
- the protruding portion 12 in the first embodiment may be provided with the air introduction portion 15 and the through hole 15a as in the second embodiment, and may be implemented in various other forms.
- the rotary abrasive according to the above-described second embodiment was prototyped, and a comparative test with a conventional rotary abrasive was performed.
- each rotating abrasive was mounted on a disk grinder, and polished at a rotation speed of 110 Omin- 1 .
- the amount and the amount of reduction in the weight of the rotating abrasive (wheel loss) were measured every 3 minutes, and the measurement was performed for a total of 30 minutes.
- each rotating abrasive used was a polishing sheet 14 with a count of 60, and 80 rotating sheets were arranged per rotating abrasive.
- the present invention has the following advantageous effects.
- the protruding portion guides the air present in the air introducing portion to one side, and Occurs.
- This airflow always passes through the air inlet during the rotation of the rotating abrasive. For this reason, the frictional heat generated between the polishing object and the polishing sheet is carried away by the air current, and the adverse effects such as deterioration of the polishing sheet and deterioration of the polishing object, which are generated by accumulation of the frictional heat, can be eliminated.
- the rotating abrasive since the position of the first member with respect to the second member can be easily switched, the rotating abrasive itself can be rotated according to necessary processing. It is possible to easily carry out polishing work without having to replace each time or use a different rotating tool with a different rotating abrasive material, and to use the invention described in claim 6 of the present application. Therefore, in addition to the effect of any one of the inventions set forth in claims 2, 3, and 5, especially when the space between the projecting portions is used as the air introducing portion, the air introducing portion is formed by a polishing sheet. Since the rotating abrasive is rotated, the airflow can be smoothly flowed to the air introduction part.
