Reusable hub assembly for abrasive articles

A method of reusing a hub in an abrasive assembly, the method comprising:

• removably coupling the abrasive wheel to a reusable hub, wherein the abrasive wheel has an outer circumference and an inner circumference, and wherein the abrasive article has an inner circumference and an outer circumference;
• abrading a worksurface by contacting the abrasive wheel to the worksurface;
• and
• wherein the reusable hub comprises:
• a coupling feature configured to directly couple to the abrasive article;
• and
• wherein the coupling feature comprises an adhesive-free connection between the reusable hub and the abrasive wheel, and wherein the direct connection is a removable interlocking between the abrasive wheel and the reusable hub.

A method for exchanging abrasive articles for a reusable hub, the method comprising:

• decoupling a first abrasive article from the reusable hub;
• coupling a second abrasive article to the reusable hub, wherein the reusable hub couples and decouples using a mechanical feature of the hub;
• and
• contacting the second abrasive article to a worksurface.
