ABSTRACT:
A roller burnishing tool for finishing the internal surface of a cylindrical hole is disclosed. The tool includes a roller race having a central axis and a frustoconical outer surface tapering radially outward and axially forward. A plurality of frustoconically tapered rollers are arranged about the outer surface for rolling engagement with the outer surface with the smaller ends of the rollers facing forward. The taper of the rollers is such that the outermost surface portion of each roller is parallel to the central axis. The rollers are biased in the forward direction with a chosen force so that the force exerted on the internal surface of the hole remains constant over a range of sizes of the hole.
