Why choose a ceramic bond grinding wheel for PCD&CBN tools? In Grinding PCD tools, because the resin bond is soft, easy to deformation during grinding, can not effectively grinding PCD tools; Metal bond due to the combination of abrasive ability is too strong and poor self-sharpening, grinding efficiency is low, and metal bond grinding wheel will cause the most serious damage to the edge of PCD tool; Considering grinding efficiency, durability and machining quality of workpiece surface, ceramic bonded diamond grinding wheel is the most suitable choice for grinding PCD tools. According to machine type and processing needs, the grinding wheel is made into various standard shapes and sizes.   Diamond grinding wheel with ceramic bond has the common characteristics of the diamond and ceramic bond: (1)Compared with common corundum and silicon carbide grinding wheels, its grinding force is stronger, grinding temperature is lower, grinding wheel wear is smaller; (2) Can adapt to the role of various coolants; (3) Good shape retention of grinding wheel and high precision of grinding parts; (4) There are many holes in the grinding wheel, which is conducive to chip removal and heat dissipation during grinding, and is not easy to block and burn the workpiece; (5) The grinding wheel has good self-sharpness, long dressing intervals, and easy dressing. The advantages of the diamond grinding wheel with the ceramic bond are as follows. 1) High grinding efficiency; 2) High wear resistance: grinding wheel has high wear resistance and less abrasive consumption, especially when grinding very hard and brittle workpiece; 3) Small grinding force and low grinding temperature; 4) The workpiece grinding high precision, has good surface quality, and good shape retention of the workpiece.
