Abstract
Composite abrasive wheels having shaped abrasive grits bonded to a fibrous substrate are more effective than their counterparts with irregularly shaped grain, especially at finer grit sizes.
Claims8
A composite abrasive product comprising a random non-woven fibrous web with abrasive particles adhered thereto by means of an organic polymer wherein the abrasive particles are shaped particles of an abrasive material having a substantially uniform cross-sectional shape along a longitudinal axis and an aspect ratio of at least 1.5:1.
A composite abrasive product in which the abrasive particles have a grit size of less than 150 grit.
A composite abrusive product in which the aspect ratio is from about 2:1 to about 6:1.
A composite abrasive wheel comprising a random non-woven fibrous web with seeded sol-gel alumina abrasive particles having a grit size of 150 or smaller adhered thereto by means of a polyurethane binder wherein the abrasive particles are shaped particles with a substantially uniform cross-sectional shape along a longitudinal axis and an aspect ratio of from about 2:1 to about 6:1.
