    Abstract
  • To address the issues of low grinding efficiency and the tendency of blockage and burning of the grinding wheel when working with ceramic materials using traditional resin and electroplated diamond grinding wheels, the feasibility of using brazed diamond technology to prepare a multilayer brazed diamond grinding wheel for ceramic grinding is analyzed. Combined with the optimization of filler metal composition, a multilayer brazed diamond grinding wheel with a slotted structure is prepared, and the grinding performance of 99.9% high-purity Al2O3 ceramics is tested. The results show that resin and electroplated diamond grinding wheels suffer from low grinding efficiency and insufficient grinding life, respectively. Single-layer brazed diamond grinding wheels exhibit high grinding efficiency but have limited grinding life. Multilayer brazed diamond grinding wheels show obvious advantages in terms of grinding life while maintaining high grinding efficiency, being about 60% higher than that of single-layer brazed diamond grinding wheels. During the ceramic material grinding process, the multilayer brazed diamond grinding wheel demonstrates remarkable grinding effectiveness. Despite the limited exposed height of abrasive particles, the slotting design significantly enhances chip removal, preventing the wheel's surface from bonding and blocking with ceramic powder.
