1) The bonding strength of the resin bond diamond grinding wheel is weak, so the self-sharpening ability during grinding can be good, not easy to block, high grinding efficiency, less grinding force, low grinding temperature, the disadvantage is poor wear resistance, large wear loss, not suitable for heavy-duty grinding.
2) The wear resistance and bonding ability of ceramic bond diamond grinding wheel are better than that of resin bond, cutting sharp, high grinding efficiency, not easy to heat and block, less thermal expansion, easy to control accuracy, shortcomings: the grinding surface is coarse, and the cost is higher.
3) Metal bond diamond grinding wheel has high bonding strength, good wear resistance, low wear, long life, low grinding cost, can withstand large load, but poor sharpness and easy to block.
4) The abrasive particle size has a certain influence on the grinding wheel blockage and cutting amount, compared with the fine sand grain, the wear of the cutting edge of the abrasive grain with large cutting depth is increased, and the grinding wheel is easy to block.
5) The hardness of the grinding wheel has a great influence on the blockage, and the high hardness of the grinding wheel has a high thermal conductivity, which is not conducive to surface heat dissipation, but is conducive to improving the processing accuracy and durability.
6) The concentration selection of grinding wheel is an important feature, which has a great impact on grinding efficiency and processing cost, too low concentration affects efficiency, on the contrary, abrasive particles are easy to fall off, but the best binder concentration range is also the best.
