The CBN attributed ceramic materials science in categories, but because of the CBN, SIN, Al2O3,  Diamond wheel the difference in performance of the SiN materials, ceramic blade is less than cubic boron nitride toughness and hardness of the blade. So according to the differences of hardness and toughness, cutting hardness below 50HRC small cut deep small case hardened steel workpiece feed ceramic blade is a better choice. CBN Grinding Wheels suitable in workpiece hardness above 50HRC situation. In addition, in the case of the same flank wear, surface residual stress of the workpiece after the cutting blade of the cubic boron nitride than ceramic inserts relatively stable. The ceramic blade is suitable for processing field, but also the choice of cubic boron nitride blade, the user can be based on cost-effectiveness and processing needs to determine what kind of blade material is more economical.
