Description

TECHNICAL FIELD

[0002] Bearing is an important component of modern mechanical equipment, which is widely used in the fields of automobile, household appliance, medical equipment, etc. With the rapid development of bearing industry, the demand for bearings with high precision and low noise is increasing. As one of the main components of bearings, the size accuracy and stability of bearing rings are also continuously improved. The processing technology of bearing rings is the key to ensure quality, and the processing technology parameters, heat treatment process and process flow sequence will affect the size accuracy and mechanical properties of bearing rings.

[0003] When machining the outer circle of the bearing ring, at least the following problems exist:

[0004] 1. When machining the outer circle of the bearing ring, the chuck is usually used to clamp from the inside to the outside, but this method is easy to cause deformation of the inner ring and leave marks. For the relatively thin wall thickness of the ring, if the pressure is too large, it is easy to cause crushing, and if the pressure is too small, it is easy to cause the ring to be clamped tightly, which is easy to cause deviation during grinding, and due to the structure of the chuck itself, there is a problem of uneven stress during grinding, which will directly affect the machining accuracy;
