ABSTRACT:
An apparatus for polishing a metal article, including a tapered mandrel adapted to be connected to a power source. The tapered mandrel is received within the tapered interior of an expandable hub that is provided with a plurality of longitudinally extending slots. One group of slots extends from one end of the hub and terminates short of the opposite end of the hub, while a second group of slots is spaced between the first slots and extend from the second end of the hub and terminate short of the first end. A series of outwardly projecting longitudinal ribs are located between adjacent slots. The hub is positioned within a resilient sleeve having a plurality of internal longitudinal grooves to receive the ribs, and the outer surface of the sleeve receives an abrasive band. By threading a stud in the outer end of the mandrel, the tapered mandrel is drawn inwardly of the hub to expand the hub and firmly secure the abrasive band to the sleeve. Through use of the ribs, an effective power transmission is obtained between the mandrel and the abrasive band to accommodate high speed, high pressure polishing of metal articles.
