在滚动轴承另件的生产施工过程中,退火工作是占有特殊地位的。它将保证金属的一定硬度和均匀的组织。这对另件以後在自动车床上的机械加工来说,是很重要的,此两种性质将限制件,在机械加工时的表面光洁度和现存零件的淬火。 所以在1ГП工厂中(国家第一轴承厂),特别注意退火这个 In the production of rolling bearing parts of the construction process, the annealing work is to occupy a special position. It will guarantee a certain degree of hardness and uniform organization of the metal. This is important for subsequent machining of parts on automatic lathes, both of which will limit the surface finish during machining and the quenching of existing parts. So in 1ГП factory (the country’s first bearing factory), pay special attention to annealing this
