    Abstract: A coated abrasive disc includes an abrasive layer disposed on a major surface of a disc backing. The abrasive layer comprises triangular abrasive platelets secured to a major surface of the disc backing by at least one binder material. The triangular abrasive platelets are outwardly disposed from the major surface at contiguous intersections of horizontal and vertical lines of a rectangular grid pattern, wherein the intersections of the rectangular grid pattern have an areal density defined by C/(LT) where C is a unitless coverage factor having a value between 0.1 and 0.4, L is the average major triangular abrasive platelet side length and T is the average triangular abrasive platelet thickness. At least 70 percent of the intersections have a triangular abrasive platelet disposed thereat. Each one of the triangular abrasive platelets has respective top and bottom surfaces connected to each other, and separated by, three sidewalls, and, on a respective basis, one sidewall facing the disc backing of at least 90 percent of the triangular abrasive platelets has a Z-axis rotational orientation within 10 degrees of the vertical lines. Methods of making and using the coated abrasive discs are also disclosed.

    Abstract: Methods of making an abrasive article..Abrasive particles are loaded to a distribution tool including a plurality of strips defining a plurality of channels. Each channel is open to a lower side of the tool. The loaded particles are distributed from the distribution tool to a major face of a backing web below the lower side..At least a majority of the particles distributed from the tool undergo an orientation sequence in which each particle first enters one of the channels. The particle then passes partially through the channel such that a first portion is beyond the lower side and in contact with the major face, and a second portion within the channel. The sequence then includes the particle remaining in simultaneous contact with one of the strips and the major face for a dwell period.

    Abstract: A coated abrasive belt (100) includes a belt backing (110) and an abrasive layer disposed thereon. The abrasive layer comprises abrasive elements (160) secured to at least a portion of a major surface of the belt backing (110) by at least one binder material. The abrasive elements are disposed at contiguous intersections of horizontal (192) and vertical lines (194) of a rectangular grid pattern. Each abrasive element has at least two triangular abrasive platelets (130), each having respective top and bottom surfaces connected to each other, and separated by, three sidewalls. On a respective basis, one sidewall of the triangular abrasive platelets is disposed facing and proximate to the belt backing. A first portion of the abrasive elements is arranged in alternating first rows (16) wherein the triangular abrasive platelets are disposed lengthwise aligned with the vertical lines (194). A second portion of the abrasive elements is arranged in alternating second rows (168) wherein the triangular abrasive platelets (130) are disposed lengthwise aligned with the horizontal lines (194). The first and second rows repeatedly alternate along the vertical lines. Methods of making and using the coated abrasive belt are also disclosed.

    Abstract: A coated abrasive article having a plurality of formed ceramic abrasive particles each having a surface feature. The plurality of formed ceramic abrasive particles attached to a flexible backing by a make coat comprising a resinous adhesive forming an abrasive layer. The surface feature having a specified z-direction rotational orientation, and the specified z-direction rotational orientation occurs more frequently in the abrasive layer than would occur by a random z-direction rotational orientation of the surface feature.

    Abstract: A coated abrasive belt includes an endless belt backing and an abrasive layer disposed thereon. The abrasive layer comprises abrasive elements secured to at least a portion of a major surface of the belt 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 at least 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 belt 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.
