Honing is a process that uses Silicon Carbide , Aluminum Oxide, CBN or Diamond tools to polish the ID of a cylindrical shaft . These tools are mounted on a mandrel that is rotated and reciprocated at the same time. Expansion of the mandrel is controlled by servo controls or hydraulically. Honing gives a surface finish of 0.1 Ra or better in most cases.
