The disclosure is generally directed to a method of manufacturing an abrasive rotary tool using a molded elastic layer. A mold includes a cavity with a peripheral surface. An abrasive sheet is positioned so that a working surface of the abrasive sheet is positioned along at least a portion of the peripheral surface. A spindle is positioned within the mold to create a region between the spindle and the abrasive sheet. An elastomeric precursor material is injected into the region and solidified to form an elastic layer. As a result, the elastic layer is in direct contact with at least a portion of the opposed surface of the abrasive sheet and at least a portion of the exterior surface of the spindle. In this way, an abrasive rotary tool may be manufactured without using adhesive layers and/or fastening means.

The present application includes methods, apparatuses, and systems for cleaning an aluminum wheel. In particular instances, a method of treating an exterior surface of an aluminum vehicle wheel comprising: blasting the exterior surface a first occurrence for a first duration at a first velocity using blasting media; blasting the exterior surface a second occurrence for a second duration at a second velocity using blasting media after blasting the exterior surface for a first duration, the second velocity being substantially lower than the first velocity; and, arranging the vehicle wheel in contact with vibratory finishing media and vibrating the vehicle wheel with the vibratory finishing media for a duration after blasting the exterior surface in each of the first and second occurrences.

A polishing tool with a carrier comprising a polishing surface on which a polishing paste is applied at least in some areas, wherein the polishing surface consists of a nonwoven fabric, the polishing paste is in a solid state at room temperature and is applied on the polishing surface to be covered in an amount of 0.08 g/cm.sup.2 to 0.30 g/cm.sup.2.

A buffing and polishing member has an uncompressed monolithic body of foam material having slits from an outside surface toward and less than a distance to a rotational axis of the body. The slits, on circumferential spaced planes, extend generally radially from the outside surface toward and less than a distance to the rotational axis to define a plurality of foam fingers and an unslit center portion. A fastening mechanism holds the center portion of the slit foam body in a compressed state along the rotational axis such that the uncompressed outer ends of the foam finger define a spherocylinder.

Systems and methods including providing a fixed abrasive buff having a central hub and a plurality of fabric layers affixed to the central hub. An abrasive composition is dispersed throughout the fabric layers and includes a polymeric binder and a plurality of abrasive particles dispersed in the polymeric binder. The content of the abrasive particles at an outer edge of the plurality of fabric layers is higher than the content of the abrasive particles at an inner edge of the plurality of fabric layers.
