摘要： A grinding wheel has a disc having a connection hole formed at a center thereof, to which a rotation axis of a grinder is connected, and a plurality of abrasive segments detachably connected to a surface of the disc. A plurality of fixing recesses are radially formed on the surface of the disc at an interval and fixing protrusions having a shape corresponding to the fixing recess are formed on bottom surfaces of the abrasive segments, so that the abrasive segments are connected to the disc by inserting the fixing protrusions into the fixing recesses. According to the grinding wheel, when the abrasive segment is worn away or inferior as it is used for a long time, it has only to replace the corresponding abrasive segment only. Accordingly, an economical efficiency is high.

摘要翻译： 砂轮具有在其中心形成有连接孔的盘，研磨机的旋转轴连接到该连接孔，以及可拆卸地连接到盘的表面的多个研磨段。 在盘的表面上以一定间隔径向形成多个固定凹槽，并且在研磨段的底表面上形成具有与固定凹槽对应的形状的固定凸起，使得研磨段通过插入而连接到盘上 固定突起进入固定凹槽。 根据砂轮，当研磨部分长时间使用时磨损或变质时，只能更换相应的研磨部分。 因此，经济效率高。
