The passengers in guangxi problem and the reason analysis of surface bearing manufacturer

Guangxi passengers bearing manufacturer analysis problems and causes of bearing ring raceway is bearing surface appearance of workpiece, its quality will directly affect the work of bearing performance and using life. In the process of using, we will often find some common quality problems, bearing ring looks such quality problem is how to produce? 1, the surface roughness is bad sources: superfinishing didn't have enough time, stone pressure is too high, millstone vibration frequency is relatively high, the essence of superfinishing workpiece speed is too low. 2, superfinishing tumor after superfinishing process on the appearance of size, shape different convex particles, this is mainly due to the grinding particles in a moment under the action of high temperature and high pressure sintering in processed appearance, its presence increases the high temperature of bearing vibration value, reduce the use of the bearing life. Sources: stone pressure is too high. Superfinishing before surface roughness value is too high, high rotating speed, smooth cutting surface is not abundant, bearing ring grinding residual magnetism is too large. 3, silk was processed after superfinishing appearance of mesh scratches. Sources: grindstone too many impurities, particle size is not the average; Lack of cutting fluid has impurities, flushing. 4, coma galaxy superfinishing process, because the individual large diamond particles is shattered or infarction in the appearance of dips, along with the superfinishing pressure and the rotation of the workpiece is coma galaxy. Sources: correct selection of stone, lower millstone. 5, grinding wheel sources: processing appearance when the grinding wheel is too coarse, coarse superfinishing when rotating speed is too high, coarse superfinishing time too short, coarse superfinishing grindstone when pressure is too small, millstone pendulum Angle is too small. 6, transverse axial momentum is too big to produce reason, artifacts of eccentricity is too small, cause the workpiece rotation is not stable, radial circular runout, millstone swing and artifacts of raceway curvature is not coincidence, workpiece positioning end bearing surface have sundry, cause transverse axial momentum is too large, geometry precision grinding process is bad, workpiece after repeatedly repair. 7, roundness, waviness bad sources: artifacts of eccentricity is too small; Pure superfinishing workpiece rotational speed is too large, provoked machine tool vibration; Stone width is not enough, Angle is too small. Roller bearing Angle when positioning is too small to drive normal ring spinning; Roundness, large ripple through the grinding process. 8, ball bearing raceway raceway curvature is bad sources: after superfinishing oscillating and raceway curvature is not coincidence: stone crossed the big wide, Angle is too large.
