A guide to technical terms used in cylinder technical specifications

Burnishing Of Tubes

Roller burnishing, or surface rolling, is used on cylinders to improve the surface finish of the tubes. Unlike grinding, burnishing is a compressive technique that creates a highly polished surface relatively free from surface ridges or asperites. This more highly polished surface allows seals to operate more effectively.

Burnishing of tubes is undertaken using a tool that resembles a roller bearing, with rollers rotating in cage. However, unlike a bearing, the rollers are generally very slightly tapered so that their surface contact can be finely adjusted.
