How did the ultra precision stainless steel bearing quality impact

We have 'super fine effect on quality of stainless steel bearings how to' to discuss the topic, people will ask: in the first place what is stainless steel bearing superfinishing? Superfinishing this procedure in the process of stainless steel bearing what role? I don't know how existing textbooks define 'super fine', but from my understanding of superfinishing for years is this: stainless steel bearing ring channel after oil stone of high frequency and low frequency oscillation and pressure, the tensile stress in the grinding process can be formed into a compressive stress, so as to get ideal surface compressive stress. The work surface can effectively reduce the vibration and noise amplitude of stainless steel bearings, can improve the service life and the fatigue strength of stainless steel bearing. The role of superfinishing summarized up to 'reduce noise, improve the life of' the eight words. We all know that the stainless steel bearing superfinishing in stainless steel bearing ring grinding processing production line at the end of the procedure, and is also a very important process, is indispensable. Before the second world war, of course, most of stainless steel bearing ring nor superfinishing, stainless steel bearing raceway and rolling body ultra lapping technology originated in the middle of the second world war, because at that time needed for military products is put forward higher reliability, stability and safety requirements, only after superfinishing technology progress and development. Mid 60 s, when I just entered on micro factory, in order to against the Soviet union blockade and spite, One tons peanuts only for 10 sets of 623 stainless steel bearing) Self-reliance, to build a 'battle' brand 23 ( 623). Stainless steel bearings. Remember the superfinishing is the way of 'shoeshine, yarn with a little green oil, on the rotating ring back and forth, up and down like shoeshine polishing. , into the factory at that time I just don't understand the production technology of stainless steel bearings, for what is a super fine don't know, is very superficial on the effect of superfinishing, only know that this cast will make ring raceway surface roughness increase, reduce the friction coefficient, which can improve the service life of the stainless steel bearing. At the same time, along with old engineer trial-produced the first club domestic super lapping machine SQ - manually 2 ( Four head superfinishing machine) Replace the 'shoeshine. After eighty s, and on this basis made of semi-automatic and fully automatic club superfinishing machine, successively developed face after superfinishing machine. More than half a century, along with the stainless steel bearing quality common ascension, more and more high to the requirement of superfinishing, understanding of superfinishing have ascension. Ultra lapping is a in the working procedure and improving the quality of the ring surface micro process, these microscopic quality including roughness, furrowed, roundness and stripes. And I also want to emphasize here is superfinishing while the most obvious characteristic is to remove the metamorphic layer on the surface of grinding process, reduce the roughness of stainless steel bearing raceway, but more important still is without destroying superfinishing process before grinding on the basis of the shape and dimension precision of conditional improvement, further improve the shape of the channel, so as to reduce the work of stainless steel bearing noise, improve its carrying capacity, service life and fatigue strength.
