1, the surface roughness is bad
Reason: superfinishing didn't have enough time, stone pressure is too high, millstone vibration frequency is relatively high, pure superfinishing workpiece speed is too low.
2, superfinishing tumor
In processing the surface after superfinishing convex particles of different sizes, shapes, and this is mainly due to the grinding particles under the action of high temperature and high pressure sintering in a flash in the processed surface, its presence increases the bearing vibration value, reduce the service life of the bearing. Reason: the millstone pressure is too high. Superfinishing before surface roughness value is too high, high rotating speed, cutting lubricating liquid cooling is not sufficient, the remanent magnetism of bearing ring grinding is big.
3, silk
After superfinishing processed surface mesh scratches.Causes: grindstone too many impurities, particle size is not uniform; Cutting fluid has impurities, insufficient rinsing.
