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.
In certain circumstances, in accordance with the concentration from low to high sequence of words, the sharpness of the saw blade will gradually decrease, but on the contrary, when the concentration is too high, the service life will be longer, the blade also become very blunt, finally resulted in the normal use. Low concentrations, Honing stone, high efficiency abroad blade universal phenomenon, but only if two conditions are met: first diamond toughness and heat resistance must be high, and the second is a binder with diamond must firmly have the edge high without premature loss. Like our domestic mostly use high concentrations of fine-grained, domestic coarse-grained, high toughness diamond can not meet the needs under the conditions forced. They also do not meet the requirements of high-end blade development trend. Matching multilayer tip structure, the various parts of the density unevenness of the tip, is an effective to improve the results.Diamond Blades sawing process, the working surface of the magnetic head, to form a groove in the middle of the intermediate blade deflection can be prevented, thereby improving the quality of the stone processing. 5 layers, 7 layers or more layer structure of the various parts of the head measured the concentration of the above adjustments, but also to receive the same effect, if properly designed, can make a diamond saw blade is sharp, high efficiency, but not will affect the service life. A low concentration can also be used the diamond doping dice can also be used metal sheet sandwich these measures are effective.
