KOYO bearing roughness effects on the quality of analysis

KOYO bearing surface roughness with standards and requirements, but in the process of grinding and Superfinishing, for various reasons, often does not meet the specified requirements. We can look at to determine the original surface roughness of bearing bearing accuracy and quality.
Cause workpiece surface roughness of bearing does not meet the requirements of the principal cause is important, now introduced in the following sections:
1. iron lathe KOYO bearings out of rigid extension plug loose, drive vibration caused by imbalance. of course, the lathe bearings installation does not arise in relation to sound vibrations, workpiece surface roughness decreases due to vibration.
2. insufficient rigidity of bearing vibrations, so use coarse tool bar as much as possible, reduce the bearing length; rigid enough can also cause the workpiece vibration, to Application Center in turning of slender shaft, or a clip to replace two top clamping.
3. cutting part of the bearing geometry parameter is not properly selected according to workpiece material machinability characteristics of reasonable and proper cutting angle, reducing the surface roughness.
4. due to the accumulated crumbs tumor, workpiece surface roughness decreases accumulated crumbs tumors are very strong, as accumulated crumbs when cutting tumor involvement of workpiece surface galling of the bearing or a road ditch marks, turning bearing should be avoided as it is produced. Analysis on the combination of the aforementioned factors, prevention should be known early in the process, the problem nipped in the bud, improve bearing the workpiece accuracy, design requirements are met.
KOYO bearings in the grinding process, its working surface is grinding through a high-speed rotating grinding wheel, grinding if you do not follow the operating instructions and adjust equipment, it appears on the bearing surface flaws, which will then affect the overall quality of the bearings. We can check the bearing quality.
