Generally speaking, the higher the pressure, the higher the grinding power. Under normal circumstances, only a small amount of pressure can be applied when grinding the sprocket. When the pressure is slightly higher, abrasive particles will be embedded on the surface of the workpiece or scratches will be formed. The special abrasive just solves the problem that all abrasives cannot be used under high pressure. It is a colloidal solution produced by a special process. All abrasive particles are wrapped by the colloidal solution. The cutting by abrasive particles changes with pressure, and the cutting by abrasive particles becomes stronger with high pressure, and vice versa.
Grinding has strong adhesion to the sprocket workpiece, and the abrasive distribution is highly uniform. During the grinding operation, the abrasive will not be thrown or splashed. Its smoothness is used, the pressure during grinding can reach the work load of the workpiece, and the surface of the workpiece to be ground has no scratches, sand-inlaid or glued, and it can be used at very high temperatures.
In the field of machinery manufacturing, grinding and polishing of high-precision sprockets, arc gears, bevel gears, internal gears, worm gears, deep holes with large slenderness ratios, special-shaped surfaces and internal surfaces, and correction of manufacturing errors in large parts and devices, Can be handled simply. For grinding soft metals, such as copper, aluminum and babbitt alloys, abrasives are generally not allowed because of the formation of scratches and embedments. This special abrasive can be used to grind this soft metal under high pressure without being scratched or embedded. Under certain conditions, we can replace grinding, scraping and honing with research.
Improving the accuracy of the sprocket has unexpected effects. For example, in order to reduce environmental noise pollution, escalator drives require low noise. The sound level is required to be lower than 60dB. How to reduce noise has become a key issue in improving product quality. After inspection, the gear processing accuracy of the transmission reducer is low, some parameters are seriously out of tolerance, and the surface roughness value is high. The machining accuracy of the sprocket is low. When the tooth surface is rough, there is only a small amount of contact when the gear is meshed, which makes the contact unstable, short deformation time and large gear swing, which are the main factors that produce noise.
