Abstract
Bonded abrasive articles and in particular organic bonded depressed center wheels with one or more reinforcements have reduced stiffness in comparison to conventional counterparts. Techniques for producing and using such wheels are described. In one example, a method for reducing the stiffness of an organically bonded abrasive wheel includes applying to a raised hub region of a reinforced depressed center wheel a force effective to irreversibly decrease the stiffness of said wheel.
