Abstract

See full text

A near-net shape forming method for fabricating the precise bearing ring forging is invented. The processing method is composed of following three procedures. (1) the precise ring-like billet with chamfer angle is manufactured by the machining method. (2) The billet is heated by the less oxidation or non-oxidation heating method before ring rolling. (3) The bearing ring forging integrating with the raceway is formed in one pass of the rolling process by the ring rolling method.
