The back pad is designed to be fixed on the polishing pad is attached to the front as a grinding disc or polishing to remove the rust blood abrasive surface, the power tool; A plurality of arc-shaped polishing pad disposed on the front surface of the back pad in a circumferential direction; A plurality of reinforcement after another alternately arranged between the between the polishing pad in a circumferential direction; And the polishing pad and the reinforcing resin layer for bonding fixed to the back pad; rust removal process, including the polishing pad and a reinforcing material, and places the to the front in the circumferential direction one after another alternately in the back pad, and polishing the surface of the abrasive material It provides for the wings polishing discs.
The subject innovation can increase the subject innovation will increase the utilization of the polishing pad fabric as they can be used in the process of each of cutting the polishing pad fabric to the arc-shaped polishing pad, the materials most in arc-shaped polishing pad, and consequently amount of wasted polishing pad fabric greatly reducing reduce product cost, can significantly improve the price competitiveness. By addition, to prevent the present design is that the volume strain of blood abrasive operator on the surface by applying a further force to the abrasive action also polishing pad of is reduced significantly, the polishing pad is damaged is friction excessively on the surface of the abrasive polishing pad is no layer is not easily broken, can execute the operation on the treated surface even a short period of time, it forms effective to remove rust or abrasive machining operation, thereby significantly extending the service life.
