GSNK Bearing is mainly engaged in the production and sales of precision bearings, cylindrical roller bearings, spherical roller bearings and other products. All employees of the company provide excellent service to each customer with full enthusiasm.

When grinding precision bearings, if the operation is not performed properly, various defects will easily appear on the bearing surface, resulting in a decrease in the overall quality of the bearing. Among the many defects, we are more curious about what factors are mainly related to the generation of helical defects?

During the grinding process of the bearing, the surface of the bearing needs to be ground by a high-speed rotating grinding wheel. If it is not carried out according to the operation instructions, defects will occur. We can see that there are traces of intersecting spiral lines on the surface of the precision bearing. After analysis, we know that such traces are inseparable from the straightness of the busbar of the grinding wheel. The pitch of these spiral lines is related to the speed of the workpiece table and the speed of the workpiece. It is also related to the fact that the axis of the grinding wheel is not parallel to the guide rail of the table.

Specifically, the rigidity of the V-shaped guide rail is not good, so that the grinding wheel is offset during grinding, but the edge of the grinding wheel is in contact with the working surface; or the grinding wheel is not well trimmed, and there are local protrusions; it may also be that the workpiece itself has poor rigidity; This is the phenomenon that does not meet the requirements.
