Abstract
A method of treating a workpiece by an abrasive article, the surface of which has a specified pattern. The abrasive article comprises a backing having at least one abrasive composite bonded thereto. The abrasive composite or composites comprise a plurality of abrasive grains dispersed in a binder. The abrasive composite or composites have a predetermined shape and are disposed in a predetermined array, which typically consists of a plurality of peaks and valleys. As a result of the method of this invention, the surface of the workpiece can be provided with a profile that is similar to or substantially identical to the inverse of the pattern of the abrasive article.
Claims5
Method of providing a pattern comprising grooves to the surface of a workpiece comprising the steps of:
- (1) providing a coated abrasive article comprising a backing bearing on at least one major surface thereof, in a non-random array, a plurality of precisely shaped abrasive composites, each composite comprising a plurality of abrasive grains dispersed in a binder,
- (2) placing the surface of said abrasive article bearing said precisely shaped abrasive composites in contact with the surface of said workpiece under sufficient pressure to provide grooves in said workpiece upon movement of said abrasive article with respect to said workpiece, and
- (3) moving at least one of the surface of said abrasive article or the surface of said workpiece with respect to the other surface in a direction so as to provide said pattern of grooves.
