Vitrified bond internal grinding wheels products have high strength, good heat resistance, sharp cutting, high grinding efficiency, not easy to generate heat and clogging during grinding, small thermal expansion, and easy to control machining accuracy. Compared with the resin bonded diamond grinding wheel, it solves the problems of low service life, low grinding efficiency and easy deformation of the abrasive tool itself during the grinding process of the resin diamond grinding wheel.
Vitrified bond internal grinding wheels products share common features of diamond and vitrified bonds:
①Compared with ordinary corundum and silicon carbide grinding wheels, it has stronger grinding force, lower temperature during grinding, and less wear of the grinding wheel; ②It can adapt to the role of various coolants; ③Vitrified bond internal grinding wheels products grinding wheel Good shape retention and high accuracy of grinding workpieces; ④ There are more pores 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 self-sharpening of the grinding wheel is relatively good, and the dressing interval It takes a long time and it is easier to repair.
Therefore, Vitrified bond internal grinding wheels products are increasingly used in some developed countries abroad.
