发明名称 SLIPSKIVA
摘要 An abrasive disc for polishing or smoothing a subfloor, for example, comprises a holder disc 8, which on the bottom side along a circular arc is provided with a plurality of evenly spaced circular-cylindrical polishing blocks 9 having an outer coating of hard-metal particles of, for example, tungsten carbide. The polishing blocks 9 are rotatably mounted on axle journals 82 and rest against the holder disc 8 via a sliding disc 99. The rotatability of the polishing blocks 9 means that their wear is more even, cuts in the floor surface are avoided, better coverage is obtained, and a self-cleaning effect is obtained for the polishing block. The polishing blocks can be tiltable by about 2 degree relative to the holder disc. <IMAGE>
