For the bearing bush processing process, we commonly have two methods: one is the centralized process, the other is the decentralized process, in order to make the bearing bush better processing, according to understand, analyze some characteristics about the bearing bush these two process methods, hope that we can help you in the bearing bush processing. A, bearing collar processing of the centralized process Bearing collar concentrated process only one process can be used to complete the turning process of one or several rings. The characteristics of the centralized process. (1) a clamping cycle can complete most or all of the turning process, reducing the clamping positioning error and clamping positioning auxiliary time, improve the location and size accuracy between the surfaces of the rings, and improve productivity. If it is a batch production of small and medium-sized rings in the multi-axis automatic lathe can be turned out 2 ~ 3 at a time. (2) shorten the process, reduce the intermediate storage, loading and unloading, transport links, easy production management; reduce the amount of machine tool equipment and tools. (3) It is conducive to the realization of automation and mass production, shortening the production cycle and reducing production costs. But at the same time, the lathe, tools, fixtures and auxiliary tools and other process equipment and workpiece blanks have high requirements. For example, it requires less amount of blank and higher accuracy in size, and more stringent requirements for surface quality such as metallographic organization and hardness; it requires larger power, rigidity and higher machining accuracy and automation of lathe, often using multi-tool, multi-step, multi-station multi-axis semi-automatic machine and automatic machine tools, generally for mass production, it is appropriate to use multi-axis automatic machine tools, for medium and small batches and variable processing models, it is appropriate to use multi-tool Semi-automatic lathe; the types and quantities of process equipment, strong specialization, trouble to change models, difficult and time-consuming adjustment, high technical level of workers, the need for reasonable production organization and management. Second, the dispersion process of bearing collar processing The bearing collar dispersion process is divided into several clamping to complete the turning process of a collar. The characteristics of the dispersion process are (1) suitable for medium and large motor SKF bearing housing installation of small batches and single production. Easy to organize production, lathe, fixtures, simple and economic, easy to replace the bearing type, low cost. If a single machine connected to an automatic line, also suitable for mass production. (2) High efficiency special lathe with good rigidity and high power can be used for processing, so that the best process parameters can be easily selected and high speed large cutting tool can be used to improve the processing efficiency. (3) on a single machine can achieve automatic loading and unloading, automatic tooling and automatic measurement, machine tools are easy to operate, the workers do not require high technology. (4) on the ring blank requirements are not high, all kinds of forms, sizes, domestic bearings and imported bearings of new and old code size specification parameters (one hundred and sixty-one) precision batch of different blanks can be adapted. But the “dispersion process” process and process route is long, processing time and the process between storage, transportation, inspection loading and unloading time is long, – a ring need to be multiple machines, multiple processes, multiple clamping positioning, multiple operations and inspection, positioning errors, poor processing accuracy. It increases the consumption of human, financial, material and energy.
