Machine tool spindle bearing failure several error maintenance introduced

Bearing assembly with normal, smooth, smooth oil not enter the suspicion of the upper half of the machine tool spindle bearing be swept away. But all inner ring channel indentation or pit type crack fatigue spalling or appearance, rather than the mold surface spalling damage, oil supply abundant when this kind of phenomenon does not attack. The foreign body and the formation of the indentation to destroy the integrity of the oil film, become the tired of premature failure of the spindle bearing by experimental research, the discriminant is correct. Develops into a 'clean' seal type bearing, won a great victory. This bearing is the original specification in a bearing with a special structure on both sides of the rubber seal, feature is that the sealing ring is mainly used to avoid dirt intrusion of bearing, and with the main purpose is to insist on oil - A machine tool spindle bearing seal ring is different. 1, after appearance feel that the quality of bearing I found a lot of customers in the process of sales in the Swedish bearing said only bearing surface brightness is of good quality and this is wrong. Light should be a kind of machine tool spindle bearing appearance raven, forming the raven reason is bearing steel can be used by standard and its cutting fluid used in the grinding process and etc. , generated by the previous two items. 2, chamfering whether brightness spindle bearing chamfer resolution not the quality of the stainless steel bearings, but reflects the processing way of bearing. Chamfering is black, after quenching heat treatment, such as this increases the hardness of bearing, and some people think that black chamfer not beautiful is not processing is complete, this is a myth. 3, which insists on frame is better than two body, is a new technology is using the integrated frame, frugal the data, but it is only for turning performance than the difference between the two bodies, etc. In general, the use of machine tool spindle bearing life has relationship with three elements, one is the quality of the bearing itself. The second is to use the environment. 3 it is device.
