Abstract: A method for manufacturing a bonded abrasive article is presented. The method includes preparing a bondable abrasive composition including abrasive particles, a binder medium and an environmentally benign pore inducing material. The environmentally benign pore inducing material is nonflammable. The method also includes forming a precursor abrasive structure from the bondable abrasive composition. The method also includes removing the pore inducing material from the precursor abrasive structure to provide a porous precursor abrasive structure. The method also includes processing the porous precursor abrasive structure to provide a bonded abrasive article.

Abstract: A method of reusing a hub in an abrasive assembly is presented that includes removably coupling the abrasive wheel to a reusable hub. The abrasive wheel has an outer circumference and an inner circumference. The abrasive article has an inner circumference and an outer circumference. The method also includes abrading a worksurface by contacting the abrasive wheel to the worksurface. The reusable hub includes a coupling feature configured to directly couple to the abrasive article. The coupling feature includes an adhesive-free connection between the reusable hub and the abrasive wheel. The direct connection is a removable interlocking between the abrasive wheel and the reusable hub.
