A method of manufacturing a rotary abrasive machining tool, the rotary abrasive machining tool including a hub and a plurality of abrasive segments mounted to the hub, the method including the steps of: mounting each abrasive segment on the hub; machining an abrading edge on each abrasive segment while the abrasive segment is mounted on the hub.

A method for producing abrasive products and an abrasive product. The abrasive products have a connector protruding therefrom, the connector being one of an interiorly-threaded hub, a protruding shaft and an exteriorly-threaded stud. The method includes a plurality of abrasive flaps secured to one another and to a disk from which the connector protrudes by adhesive. The improvement includes forming the connector separately from the disk and securing thereto after the plurality of abrasive flaps have been secured to the disk.

An abrasive tool comprises an arbor having a body formed with an internal bore, a mounting plate disposed on the arbor, a cover plate, an abrasive article disposed between the mounting plate and the cover plate, and at least one internal resilient member disposed within the internal bore of the arbor.

An abrasive grinding wheel (10) that comprises an annular body (20) made of abrasive material provided with a central hole (21) and a reducing ring (30) provided with a central attachment hole (32), wherein the reducing ring (30) is inserted into the central hole (21) so that the attachment hole (32) of the reducing ring (30) is coaxial with respect to the central hole (21) of the annular body (20), wherein the reducing ring (30) comprises two opposing enlarged axial end stretches (311 and 312) configured to axially lock the reducing ring (30) to the central hole (21) of the annular body (20).

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.
