Abstract: A coated abrasive disc includes a disc backing and an abrasive layer disposed thereon. The abrasive layer comprises abrasive elements secured to a major surface of the disc backing by at least one binder material. The abrasive elements are disposed at contiguous intersections of horizontal and vertical lines of a rectangular grid pattern. At least 70 percent of the intersections have one of the abrasive elements disposed thereat. Each of the abrasive elements has two triangular abrasive platelets. Each one of the triangular abrasive platelets has respective top and bottom surfaces connected to each other, and separated by, three sidewalls. On a respective basis, one sidewall of at least 90 percent of the triangular abrasive platelets is disposed facing and proximate to the disc backing. The abrasive elements are arranged such that the triangular abrasive platelets in orthogonally adjacent abrasive elements have a Z- axis rotational orientation within 10 degrees of perpendicular to each other. Methods of making and using the coated abrasive disc are also disclosed.

Abstract: A flexible abrasive member (10), comprising a substrate (12), which carries an array of deposits (20) with embedded abrasive particles (22), wherein each deposit (20) has an elongated continuous structure that extends along a center trajectory (Ax) predominantly in a longitudinal direction (X) across the substrate. The structure comprises inset portions (24) and recessed portions (26), which protrude oppositely along a transverse directions(±Y) from the center trajectory, and wherein the inset portions of a deposit are accommodated in the recessed portions of a transversely preceding deposit, and the recessed portions of the deposit accommodate the inset portions of a transversely following deposit, so that the inset portions and recessed portions of neighboring deposits mutually overlap in said transverse directions.

Abstract: An article includes a polishing layer that includes a plurality of raised cells separated by a plurality of channels. Each of the plurality of raised cells includes a microstructured working surface, a substantially vertical channel surface, and an offset surface between an edge of the working surface and an upper edge of the channel surface. The microstructured working surface includes a plurality of microstructures. Tops of the plurality of microstructures define a top plane and bases of the plurality of microstructures define a base plane. The substantially vertical channel surface defines a wall of a channel of the plurality of channels and the channel surface defines a channel plane. The offset surface includes a nonplanar portion of displaced material. The displaced material defines a displacement plane that is below the base plane or within a tolerance of the top plane.
