Among them, the material of the abrasive block 701 is cerium oxide, and its hardness is lower than that of the LCD panel, which can reduce the risk of accidental scratches or damage to the LCD panel. At the same time, the abrasive block 701 made of cerium oxide has self-sharpening property, that is, the abrasive particles will naturally remain sharp during the grinding process, which helps to improve the grinding efficiency and extend the service life of the abrasive block 701, and can adapt to two different grinding processes: wet grinding and dry grinding.
