Selection and balance of grinding wheels

First, the selection of the grinding wheel of the plane grinding machine. Wrasual When the material of the wear gear is hardened steel and high-speed steel, abrasive should be used with white gogma (WA), chrome corundum (PA) or mixed abrasive of white god jade and chrome. 2. The higher the hardness of the hardness, the higher the hardness of the gear, the sooner the hardness of the grinding wheel. When using the shaped grinding wheel, due to the contact surface of the grinder, it is easy to burn the tooth surface, and the slightly soft grinding wheel should be used, but to keep the geometric precision of the grinding wheel, it is not soft. When dry mill, the hardness of the shew wheel is also soft due to heat dissipation. 3. The selection of particle size particle size should ensure that the gear’s tooth surface accuracy and outer surface roughness require the higher the precision of the tooth surface and the lower the outer surface roughness value, the finer the particle size should be fine. 4. The binding agent generally uses a functionally stable ceramic binding agent. If it is high-speed grinding, special ceramic binders suitable for high speed grinding should be selected. When the tooth surface precision and the outer surface roughness of the wear gear are high and the grinding margin is relatively large, **** can choose the thickness and fine grinding of the grinding wheels of different hardness and particle size. Second, the balance gear grinding of the planar grinding machine is precision machining, the balance of the grinding wheel is important. Otherwise, the grinding wheel will generate oscillations, which will affect the precision and outer surface roughness of the gear tooth surface, and even affect the life of the gear grinding machine when grim. The grinding wheel is necessary to pass two static balances, **** will then have a coarse wheel after balance, and then carry out balance, ** refines the grinding wheel. For worm grinding wheels, due to its size, the quality is necessary, it is necessary to make a wives, and ensure that the grinding gear has a higher precision and lower outer surface roughness value.
