For the processing of bearing sleeves, we commonly have two methods: one is a centralized process, and the other is a decentralized process. In order to make the bearing rings better processed, according to the understanding, analyze the relevant bearing rings Some characteristics of these two process methods hope to be helpful to everyone in the processing of bearing rings. Concentrated process for bearing ring machining The concentrated process of bearing rings can complete the turning process of one or several rings in only one process. Features of centralized process (1) Most or all of the turning processes can be completed in one clamping cycle, which reduces the clamping positioning error and clamping positioning auxiliary time of the ferrule, improves the position and dimensional accuracy between the surfaces of the ferrule, and improves productivity. If medium and small ferrules are produced in batches, 2~3 rings can be turned out at a time on a multi-axis automatic lathe. (2) The technological process is shortened, the intermediate storage, loading and unloading, and transportation links are reduced, and production management is facilitated; the amount of machine tools and tools is reduced. (3) It is conducive to realizing automation and mass production, shortening the production cycle and reducing production costs. Distributed process for bearing ring machining The dispersing process of the bearing rings can only be completed in several clampings – the turning process of a ring. Features of Dispersed Process (1) It is suitable for small batch and single-piece production of medium and large motor bearing housings. Easy to organize production, simple and economical lathes and fixtures, easy to replace bearing models, and low cost. If a single machine is connected into an automatic line, it is also suitable for mass production. (2) It can be processed by a high-efficiency special lathe with good rigidity and high power, which is convenient for selecting the best process parameters, and can be cut with high-speed and large-feed cutting, which improves the processing efficiency. (3) For a single machine, automatic loading and unloading, automatic cutting and automatic measurement can be realized. The machine tool is easy to operate and does not require high technology for workers. (4) The requirements for the blank of the ferrule are not high, and blanks with different precision and batch sizes can be adapted to various types, sizes, new and old code size specification parameters comparison table of domestic bearings and imported bearings (161). However, the “dispersed process” has many processes and long process routes, and the processing time and the time for storage, transportation, inspection, loading and unloading between processes are long. A ferrule needs to be multi-machine, multi-process, multiple clamping and positioning, multi-person operation and Check, the positioning error is large, and the machining accuracy is poor. Increased consumption of people, property, materials and energy.
