Bearing ring processing technology method and characteristics of the analysis

For bearing sleeve machining process, we have two kinds of common methods: one is focus on process, the other is a dispersion process, in order to make better bearing ring processing, dongguan LingNa machinery according to the understanding, analysis of the bearing ring some characteristics of these two kinds of process methods, hope to be of help in the bearing ring processing. A concentration, bearing ring processing process bearing ring concentration process in a process can be completed one or a few ring turning processing. The characteristics of the centralized process: ( 1) A clamping loop can complete most or all of the turning process, reduce the clamping ring position error and the clamping positioning auxiliary time, improve the position between the various surfaces of the ferrule and dimensional accuracy, improve the productivity. If the batch production of medium and small ring in multi-axis automatic lathe on cars in the last 2 ~ 3. （ 2) Shorten the process, reduce the intermediate storage, loading and unloading, and transportation links, convenient for production management; Reduced the amount of machine equipment and tool. （ 3) Is helpful to realize automation and mass production, shorten the production cycle, reduce the production cost. But at the same time on the lathe, cutting tool, jig and auxiliary tools such as process equipment and workpiece blank have higher requirements. Such as requiring size has higher accuracy, less allowance and blank on the microstructure and hardness of surface quality requirements is strict; For lathe has bigger power, rigid and high machining accuracy and automation degree, often using multiple blade, multiplex step, multi-station multiaxial half automata and automatic machine, the general mass production appropriate USES multi-axis automatic machine, for medium and small batch and processing model and changeable appropriate USES multi-tool semi-automatic lathe; The amount and type of process equipment, strong specificity, replacement model in the trouble, adjust the difficult and time consuming, workers' technology level the demand is higher, need reasonable production organization and management. Second, the procedures of dispersing process bearing ring of bearing ring processing will clamping points several times to complete - A ring of turning processing. The characteristics of dispersion process: ( 1) Suitable for medium and large motor SKF bearing installation of small batch and single production. Easy to organize production, lathe, clamping apparatus is simple, economic and easy to replace the bearing type, the cost is low. If a single machine, automatic line is also suitable for mass production. （ 2) Can use good rigidity, large power efficient special lathe processing, easy to select the best process parameters, high-speed big knife cutting are available, and improve the processing efficiency. （ 3) For single machine can realize automatic up-down material, automatic feeding and automatic measurement, machine easy to operate, the workers' demands for technology is not high. （ 4) To ring blank request is not high, all kinds of form, size and domestic bearings with imported bearings of the old and new code size parameter table ( One hundred and sixty-one). Precision of different batch of blank can adapt. But 'dispersing process 'process and the process route long, storage and transportation, processing time and working procedure between stop check the time is long, such as loading and unloading A ring need to the machine, process, multiple clamping position, many people and check the operation, large positioning error, machining accuracy is poor. Increased people, money, material and energy consumption.
