Problems solved by technology

However, the current use of double-plane polishing equipment to polish cylindrical surfaces is still limited to the use of free abrasives. It usually needs to go through three processes: grinding, rough polishing and fine polishing, and the processing efficiency needs to be improved.

Abstract

The ultra-precision polishing method of cylindrical rollers includes: using double-plane lapping and polishing equipment to rough and finely polish the cylindrical surface of cylindrical rollers; both the upper and lower polishing discs installed on the double-plane lapping and polishing equipment are semi-fixed Abrasive polishing disc; the semi-fixed abrasive polishing layer contains: 31-36wt% of α-alumina particles, 22-25wt% of cerium oxide particles, 23-27wt% of colloidal silicon dioxide, and the balance is a binder The particle size of the α-alumina particles is 0.02-15 microns; the particle size of the cerium oxide particles is 0.01-5 microns; the binder is composed of adhesives and additives, wherein the adhesives account for 60-80 wt%. The method has the characteristics of high polishing precision, high processing efficiency, high surface finish of cylindrical rollers, and high batch consistency.

Description

technical field [0001] The invention relates to the technical field of ultra-precision machining, in particular to an ultra-precision polishing method for cylindrical rollers. Background technique [0002] Bearings are important and key basic components in the equipment manufacturing industry, which directly determine the performance, quality and reliability of major equipment and host products, and are known as the "heart" components of equipment manufacturing. Precision cylindrical rollers are the key parts of bearings, and their surface quality (precision, consistency, etc.) plays a vital role in the working performance and service life of bearings. [0003] At present, abrasive polishing and centerless polishing are the main methods for ultra-precision polishing of cylindrical rollers. Abrasive polishing can be roughly divided into two types: free abrasive polishing and fixed abrasive polishing. Fixed abrasive polishing has a high material removal efficiency. With the ...
