Abstract
The invention relates to a grinding process method of an ultra-light narrow bearing sleeve ring. Compared with the original process, the grinding process method is characterized in that one-time additional annealing is added, one-time grinding circulation is added, a ceramic forming cutter is adopted, and disposable hard turning chamfering is carried out on an assembling chamfer of a bearing part on a turning lathe according to the size requirement of a finished product. According to the grinding process method, the stress in the bearing sleeve ring is effectively released, so that the residual stress is smaller, further the stability of the performance of the sleeve ring is increased, the chamfer size requirement of the finished bearing product is guaranteed, the appearance is bright, the inconsistent size of the assembling chamfers of the finished bearing products is avoided, the collision of a chamfer surface is reduced and the chamfer size of the part of the finished bearing product is not limited by lathe workers for all the processing surfaces.
Description
Technical field
The present invention relates to a kind of mill technological method for processing, specifically relate to the mill technological method for processing of the light narrow bearing ring of a kind of super spy.
Background technology
The processing of bearing assembling chamfering and the control of chamfer dimesion size are for the installation of bearing, and service life and outward appearance are all extremely important.In the mill technological method for processing of the light narrow bearing ring of existing super spy with Vehicle Processing part car chamfering, heat-treat, roughly grind plane, corase grind external diameter, outer fissure, outer internal diameter again, additional tempering, fine grinding plane, external diameter, outer fissure, the correct grinding external diameter, matching surface, polishing raceway groove, mating surface, magnetic powder inspection, demagnetization, cleaning, part is inspection eventually, at last warehouse-in.Because the characteristic of super special light narrow bearing itself instigates the stability of lasso itself not strong,, inside causes lasso oneself distortion if existing stress just to return.And traditional bearing assembling chamfer processing method is difficult to the effectively dimensional requirement of assurance bearing parts finished product, and chamfering is not of uniform size, and the outward appearance bump injury is serious, has directly influenced the oeverall quality requirement of bearing.
Summary of the invention
Defective in view of the prior art existence, the objective of the invention is to provide a kind of more effective bearing ring internal stress that discharged, make residual mechanical stress littler, increased the stable performance of lasso, guaranteed the chamfer dimesion requirement of bearing completed products, the outward appearance light has avoided bearing completed products assembling chamfer dimesion not of uniform size and reduced the bump injury of chamfer surface, and the chamfer dimesion of bearing completed products part no longer is subjected to the mill technological method for processing of super spy light narrow bearing ring of the restriction of each finished surface turner.
For achieving the above object, the technology used in the present invention solution is: the mill technological method for processing of super special light narrow bearing ring is: the Vehicle Processing part, car safety chamfering, heat-treat, each machined surface of corase grind plane, external diameter, outer fissure, outer internal diameter, once additional tempering, 180 ℃～200 ℃, 2～4 hours, adopt the ceramics forming cutter again, assembling chamfering to bearing parts on lathe requires to carry out disposable hard car chamfering according to finished size, can guarantee the chamfer dimesion requirement of bearing parts finished product like this; Each machined surface of fine grinding plane, external diameter, outer fissure again, secondary adds tempering, the matching surface of finished plane, external diameter, outer fissure, external diameter, magnetic powder inspection, demagnetization is cleaned, and part is inspection eventually, at last warehouse-in.The present invention increases an additional tempering, increases a grinding circulation; The more effective bearing ring internal stress that discharged makes the littler stable performance that increases lasso of residual mechanical stress.
Because the present invention has the more effective bearing ring internal stress that discharged, make residual mechanical stress littler, increased the stable performance of lasso, guaranteed the chamfer dimesion requirement of bearing completed products, the outward appearance light has avoided bearing completed products assembling chamfer dimesion not of uniform size and reduced the bump injury of chamfer surface, and the chamfer dimesion of bearing completed products part no longer is subjected to the characteristics of the restriction of each finished surface turner, having optimized existing technology, is a kind of new process with promotional value.
The specific embodiment
The mill technological method for processing specific implementation process of the super special light narrow bearing ring of the present invention is: advanced driving processing parts, car safety chamfering, heat-treat, each machined surface of corase grind plane, external diameter, outer fissure, outer internal diameter, once additional tempering, 180 ℃～200 ℃, 2～4 hours, adopt the ceramics forming cutter again, the assembling chamfering to bearing parts on lathe requires to carry out disposable hard car chamfering according to finished size; Each machined surface of fine grinding plane, external diameter, outer fissure again, secondary adds tempering, the matching surface of finished plane, external diameter, outer fissure, external diameter, magnetic powder inspection, demagnetization is cleaned, and part is inspection eventually, at last warehouse-in.
