A grinding tool (1) has a replaceable abrasive (4). A grinding layer (9) of the abrasive (4) faces a drive shaft (2) of the grinding tool (1). This enables a grinding of a workpiece (W) while exerting a tensile force (F). Surface areas (O) of the workpiece (W) facing away from a processor may thus be processed easily and flexibly.

A grinding wheel includes a support body which has a circumferential surface and a central coupling region for attaching the grinding wheel to a rotary drive for rotating the grinding wheel about a rotational axis running through the central coupling region. The grinding wheel also includes a grinding layer which is applied onto the circumferential surface of the support body. The support body includes a first part and a second part connected to the first part. The first part has the circumferential surface, and the second part has the coupling region and consists essentially of a vibration-damping material.

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 skate blade sharpening system used to sharpen the blades of ice skates. The skate sharpener can include a housing that includes an elongated slot for receiving the blade of an ice skate for sharpening, and clamp jaws for retaining the skate. The housing can include at least one slot cover to engage the skate blade. Engagement of the skate blade can be sensed by a controller to enable sharpening operations to proceed. The skate blade sharpening system can automatically operate a grinding wheel and move the rotating grinding wheel back and forth along the lower face of the skate blade a desired number of times to sharpen the skate blade.

A self-centering grinding wheel assembly that includes a spindle shaft including a conical-shaped end, a grinding wheel, and a grinding wheel adapter. The grinding wheel adapter affixed to the grinding wheel. A plurality of alignment members disposed radially within the grinding wheel adapter. Each of the plurality of alignment members include a tapered surface that conforms to a conical end of the spindle shaft. The plurality of alignment members slide radially with the grinding wheel adapter. The plurality of alignment members self-center the grinding wheel adapter on the spindle shaft in response to the grinding wheel adapter being assembled to the conical end of the conical shaft.

A grinding wheel center hole protection pad is provided, which mainly include a positioning portion attached to the peripheral thereof and the guiding portions disposed at the center hole at the axial center thereof. The guiding portions serve as the isolation layer between the center hole of the grinding wheel and the peripheral plate guiding wall of a flange plate. Therefore, the grinding wheel can be closely attached to the flange plate during the assembling process to decrease eccentricity. Accordingly, it is not necessary to perform the cutting calibration process and balance adjustment by a cutting machine, which can reduce the waste of manpower and material resources.

The method is for producing a disk of the type having a central hub surrounded by an abrasive material, the hub having an aperture of the type provided in abrasive discs sold by Robert Bosch GmbH under the trademark X-LOCK, the method comprising the steps: positioning a metal hub against an abrasive disc, the metal hub having an annular portion and a plurality of tabs, the annular portion defining an aperture of the type provided in abrasive discs sold by Robert Bosch GmbH under the trademark X-LOCK and the plurality of tabs protruding from the annular portion, against an abrasive disc, the abrasive disc having a central void, and the positioning being such that the metal hub occludes the central void and the tabs protrude through the disc; and bending the tabs such that the abrasive disc is gripped between the annular portion and the tabs.

The disclosure provides abrasive rotary tools with enhanced adhesion of an abrasive layer. Exemplary abrasive rotary tools include a securing element configured to secure an abrasive layer to an abrasive rotary tool. The securing element may be positioned over a portion of the abrasive layer, such as a tab or end, such that repeated forces on the abrasive layer do not decouple the abrasive layer from the rotary tool. In this way, an abrasive rotary tool may maintain a contact surface integrity through repeated use for extended life of the rotary tool.
