Therefore, the existing fine-grained or ultra-fine-grained superhard grinding wheels are mostly ceramic bond. However, the surface quality of the workpiece ground by the ceramic bond diamond grinding wheel is slightly inferior to that of the resin bond grinding wheel, and the main reason is that the toughness of the resin bond is better than that of the ceramic bond. In the prior art, in order to obtain better surface quality, a method of toughening and modifying ceramic bond is generally adopted to improve the toughness of a ceramic bond grinding wheel, but the effect is still not obvious, and the requirement of precise grinding cannot be met.
