Abstract

The invention discloses a machining technology for a rolling bearing ring. The machining technology includes the following steps that firstly, discharging is conducted; secondly, cold rolling forming is conducted; thirdly, heat treatment quenching and tempering are conducted, wherein annealing is conducted, steel is heated to the temperature higher than the austenite transformation temperature, heat preservation is conducted for 20 min to 60 min, then the steel is cooled to be lower than 500 DEG C along with a furnace and is discharged out of the furnace to be cooled in air, normalized steel is heated to be higher than Ac3 or Accm, heat preservation is conducted for 20 min to 60 min, the normalized steel is taken out from the furnace to be cooled in air, steel or an alloy is heated to the temperature higher than the critical temperature Ac1 or Ac3 by 30 DEG C to 50 DEG C through quenching, heat preservation is conducted for 20 min to 60 min, and then the steel or alloy is rapidly cooled in a medium such as water or oil or the like; fourthly, grinding is conducted; and fifthly, demagnetization and cleaning are conducted. By means of the machining technology for the rolling bearing ring, due to the fact that all the steps are optimized and parameters such as the temperature are accurately controlled, the machining quality of the bearing ring is improved, and the service life is prolonged.
