Bearing the internal organization of the material change by heat treatment to increase its hardness, wear resistance and surface quality. FAG bearing heat treatment process, the process parameters (temperature, heating rate, thermal insulation, heating and cooling, cooling rate, etc) on the performance impact of FAG bearings, practice has shown that: FAG bearings in the heating and cooling process, the FAG bearing surface temperature and temperature difference (uneven uneven heating and cooling) is a major factor of bearing deformation. Therefore, the heat treatment process for selecting reasonable is the key guarantee FAG bearing performance.
Heat treatment performance and demanding and the shipment of products are closely related, for a single-part production or supply less than 500 pieces per year of products, you can do so for heat treatment, directly by 45 plates or forged FAG bearing cavity rough machining, polishing, deburring, the entire process is relatively simple. And for large bulk FAG bearing of heat treatment, first, will roughing bearing rough for adjustable mass processing, adjustable mass Hou are tempered sorbite, hardness for 33~38HRC, improve FAG bearing heart Department mechanical performance; again on bearing for nitride processing, make FAG bearing hardness moderate, cutting performance good, to guarantee type cavity of size precision and reduced surface rough degrees; last on processing products for fine processing.
