Abstract
The surface quality of cylindrical rollers has a great influence on the working life of rolling bearings. In the paper, double-side lapping machine and flannelette pads are applied to polish the cylindrical surface of rollers. After 20 min polishing, rollers with smooth surface are obtained and the roundness of the rollers have a improvement of about 0.3 μm, which means that the polishing process based on double-side lapping method can effectively improve the surface quality and geometric accuracy of cylindrical rollers.
