Abstract:
An abrasive article having sheet-like structure including a major surface extending within an imaginary plane with a plurality of individual three-dimensional abrasive composites deployed in fixed positions thereto in an array, each of the composites has abrasive particles dispersed in a binder and has a substantially precise shape and a distal end, where another imaginary plane extends parallel to and is spaced from the first imaginary plane and intersects the lowest distal end among the composites, wherein any imaginary line drawn within the latter-mentioned imaginary plane in the direction(s) of intended use intersect at least one cross-section among the abrasive composites in the array. The invention also relates to methods for manufacturing such an abrasive article and its usage to refine a work surface.
