User when necessary to SKF bearing factory is put forward to extend the service life of SKF angular contact ball bearing of process quality requirements, such as stress state and on the surface of the rolling processing metamorphic layer control requirements. Generally speaking, the rolling surface in the moderate compressive stress state is better, but also in combination with surface from grinding to superfinishing stress rate, to determine the most conducive to SKF angular contact ball bearing fatigue life of the process parameters, in this respect, should obtain SKF angular contact ball bearing with the related professionals can be solved. Metamorphic layer mainly refers to the oxide layer on the surface of the rolling and work hardening layer and distortion on the physical and chemical properties such as other surface layer with the substrate metal, they are often very poor strength and combined with matrix is not firmly, pain of SKF angular contact ball bearing fatigue life and wear life is very bad, appropriate control. For high precision SKF angular contact ball bearings, as required by the rolling surface roughness is small, if inappropriate technological means, the high bright and clean surface, is not formed by the cutting of crowded but grits, formed by the surface shall be formed by plastic flow metamorphic layer, actually to SKF angular contact ball bearing life is very bad, should also be controlled.
