Abstract: Method and apparatus for shaping the edge (103) of a rigid, brittle materials such as ceramic plates and rigid composite plates utilizing a resin-bonded abrasive wheel.

Abstract: Abrasive articles having an encapsulated lubricant are described. In one aspect, the articles are characterized by a base substrate comprising a plurality of polymeric fibers adhered to one another at mutual contact points, the substrate having a base weight within the range from 20 to 10,000 g/m.sup.2, abrasive grains adhered to the substrate and a plurality of lubricant capsules adhered to the substrate the capsules comprising a continuous shell with lubricant therein, and the shell comprising a cured thermosetting resin. In another aspect, a composite abrasive article is characterized by at least two layers of the aforementioned abrasive article compressed together and adhered by a binder, the composite article having a flexural modulus of not more than 100 kgf/cm.sup.2.
