摘要：A manufacturing method of precision machine tool bearing with high precisionstability includes the procedures: (1) microstructural stabilization of bearing body: bycold ring rolling, two liquid quenching, ultrasonic assisted multiple cryo-temperingtreatment and stress ageing treatment, the bearing body with high microstructurestability can be obtained; (2) precision machining; (3) internal stress relaxation of bearingbody: after precision machining, by executing magnetic treatment on the bearing body,bearing ring with high microstructure stability and low internal stresses can be obtained;and (4) bearing assembly: finally precision machine tool bearing with high precisionstability can be obtained. Considering that the critical factors affecting the precisionstability of bearing is the degree of microstructure stability and internal stresses, byimproving the microstructure stability and reducing residual stress in multistagemanufacture phase, precision stability of precision machine tool bearing should bepromoted.
