Abstract
A process and apparatus for finishing the surface of a guide roller uses a drive belt under tension to ensure a uniform surface finish. Prior to surface machining, bearings at el. are inserted into the central bore of a guide roller sleeve to form a guide roller assembly. The assembly is mounted loosely on a stationary shaft and driven to rotate by an endless drive belt at a known tension. A cutting bit machines the outer surface of the sleeve as it rotates. The bit pressure against the sleeve is less than the frictional force of engagement between the guide roller and the belt.
