Bearing raceway machining process

Abstract

The invention relates to a bearing raceway machining process, which comprises the steps of: (1) mounting a turning tool on a numerical control turning tool table, and detecting the mounting precision;(2) carrying out three-cutter machining in a constant linear speed cutting mode; (3) and finishing a raceway. The bearing raceway machining process is not affected by the diameter of the machined workpiece, has universality, just needs to change a machining program when the specification changes, and is conductive to machining products with few batches and miscellaneous specifications.

Description

technical field [0001] The invention relates to the technical field of bearing processing, in particular to a bearing raceway processing technology. Background technique [0002] The raceway of the bearing is generally trimmed and ground by diamond roller profiling, which is greatly affected by the accuracy of the roller, the roller shaft, the grinding wheel shaft and the material of the grinding wheel; it is difficult to achieve shape and position tolerances when grinding by profiling The uniformity of the groove affects the groove shape and size; the grinding process is prone to grinding heat and raceway burns, and unqualified items such as elliptical deformation of the raceway and cracks on the surface of the raceway occur from time to time; the raceway is affected by rolling during the grinding process. Due to the influence of elliptical deformation produced by processes such as quenching, it is easy to produce ghosting errors in grinding processing, which affects grindi...

[0002] The raceway of the bearing is generally trimmed and ground by diamond roller profiling, which is greatly affected by the accuracy of the roller, the roller shaft, the grinding wheel shaft and the material of the grinding wheel; it is difficult to achieve shape and position tolerances when grinding by profiling The uniformity of the groove affects the groove shape and size; the grinding process is prone to grinding heat and raceway burns, and unqualified items such as elliptical deformation of the raceway and cracks on the surface of the raceway occur from time to time; the raceway is affected by rolling during the grinding process. The influence of the elliptical deformation produced by the first quenching and other processes is easy to produce ghosting errors in grinding processing, which affects the grinding accuracy and processing efficiency
