Large-cycle water-aqua grinding process for precision steel ball

Abstract

The invention discloses a large-cycle water-aqua grinding process for a precision steel ball. In the large-cycle water-aqua grinding process, a bearing steel ball subjected to preliminary machining is machined by adopting a large-cycle machining method. The process is characterized in that an aluminum trioxide solution is used as a water-aqua grinding material in the large-cycle machining method for fine grinding of the steel ball, and a precision steel ball finished product is produced. The large-cycle water-aqua grinding process disclosed by the invention has the advantages that aluminum trioxide (Al2O3) superfine micro powder is used in an aqueous fine grinding liquid, so the pollution of chromium sesquioxide (Cr2O3: a grinding material used in an oil agent machining method) to the environment is reduced, the production operating condition of the steel ball is improved, and the health of operators can be guaranteed; the surface roughness value of the steel ball subjected to fine grinding with the water aqua is small, and the geometric accuracy can meet requirements; the surface quality of the steel ball is improved, and the surface defect is reduced obviously; and the process has an obvious effect on decreasing the vibrating value of the steel ball.

Description

technical field [0001] The invention relates to a manufacturing process of steel balls, in particular to a manufacturing process of producing precision bearing steel balls by adopting a large-cycle processing form and adopting a water agent processing method to carry out finishing treatment on the initially processed bearing steel balls . Background technique [0002] The traditional steel ball finishing process is an oil processing method, which is divided into small cycle finishing, single disc closed finishing and single groove finishing. The production efficiency is low, it cannot adapt to mass production, and it is difficult to improve the accuracy, and the surface roughness Guaranteed. Contents of the invention [0003] The main task of the present invention is to provide a large-circulation water agent finishing process for precision steel balls, in particular to a large-circulation water agent finishing process capable of producing precision steel balls with high ...
