Abstract

The invention discloses a machining technology for a bearing ring. The machining technology comprises the following steps of 1 rough turning, 2 semi-finished turning, 3 one-time natural aging, 4 one-time finished turning, 5 second-time natural aging, 6 outer diameter grinding and 7 second-time finished turning. According to the machining technology for the bearing ring, by conducting rough turning, semi-finished turning, one-time natural aging, one-time finished turning, second-time natural aging, outer diameter grinding and second-time finished turning, the bearing ring with the higher roundness degree and concentricity can be machined, and the machining finished product rate is effectively increased by 30% and can reach 98%.

Description

technical field [0001] The invention relates to a bearing ring, in particular to a processing technology for the bearing ring. Background technique [0002] A bearing ring is a ring-shaped part. At present, a bearing ring made of nickel-based alloy material is very difficult to process due to its thin wall thickness of only 6mm. It is difficult to meet the accuracy requirements in ordinary machining, and the roundness, The concentricity is poor, and the processing molding rate is only about 60%. Therefore, it needs to be solved urgently. Contents of the invention [0003] The purpose of the present invention is to provide a processing technology for bearing rings, so as to solve the problem that the existing nickel-based alloy bearing rings have a small wall thickness, are difficult to process, and the processed products have poor roundness and concentricity, and the processing molding rate is low. question. [0004] The purpose of the present invention is to realize th...
