Abstract
A belt polishing machine has a moving endless abrasive coated polishing belt that wraps around and travels over a substantial portion of a circumferential surface of a rotatable workpiece for finishing the surface. A drive pulley drives the polishing belt in a continuous path at a desired surface speed over the circumferential surface of the workpiece while the workpiece is being rotated at a desired rotational speed. Guide pulleys direct the polishing belt around and into engagement with a substantial portion of the circumferential surface and may supply tension to the polishing belt during finishing operations. Separate tensioning pulleys may be provided. A coolant feed applies coolant against the polishing belt for separating and carrying away removed material from the belt and cleaning the abrasive for a subsequent pass. A backup shoe may be provided to selectively apply additional pressure through the belt upon portions of the polished surfaces to improve cylindricity. In-process gaging of the surfaces during the polishing process may also be provided.
