<p>An abrasive article is described that i.epsilon. particularly suitable for use as a grinding wheel that is composed of a resin bond, abrasive grains and a support material, including a coupling agent to adhere the abrasive grains and support material tenaciously to the organic bonding material. The support material may include hollow bodies, such as microbubbles of glass or alumina or the like, and the support material is used in an amount that is carefully controlled to produce the desired porosity in the abrasive article. A process for producing grinding wheels is also described. A wide range of controlled porosity levels in the respective grinding wheels produced may be accomplished resulting in the production of wheels having superior wet strength and dimensional stability.</p> |
