Development of Multilayer Brazed Diamond Grinding Wheel for Ceramic Precision Grinding

In order to solve the problems of low grinding efficiency and easy blockage and burn of grinding wheel when grinding ceramic materials with traditional resin and electroplated diamond grinding wheel, the feasibility of using brazed diamond technology to prepare multilayer brazed diamond grinding wheel for ceramic grinding is analyzed. Combined with the optimization of filler metal composition, the multi-layer brazed diamond grinding wheel with slotted structure was prepared, and the grinding performance of 99.9% high-purity Al2O3 ceramics was tested. The results show that the resin and electroplated diamond grinding wheels have the problems of low grinding efficiency and insufficient grinding life respectively. The single-layer brazed diamond grinding wheel has high grinding efficiency but limited grinding life. The multi-layer brazed diamond has obvious advantages in grinding life while maintaining high grinding efficiency. In the process of ceramic material grinding, the grinding effect of multilayer brazed diamond grinding wheel is remarkable. Although the exposed height of abrasive particles is limited, the chip removal effect of slotting design is significant, and the surface of grinding wheel is not easy to bond and block ceramic powder.
