We grind a sintered tungsten ball of about 32Rc. Non of our operators have any experience in ball grinding and very few have very limited manufacturing experience. Our tolerances are loose (+/- .002")and do not need a finish grind or lap. We have a process in place. This process though, I believe his cause for our problems.
Grinding Grinding is the final processing of bearing ring and roller, it is called finished product processing. The main purposes of grinding process: 1. To make the bearing ring and roller be in accordance with the design requirements in size and shape precision. 2. To prepare qualified rings and rollers for bearing assembly. Grinding
