Abstract: Structured abrasive articles include a backing and shaped abrasive composites secured to the backing. The shaped abrasive composites include abrasive grits dispersed in a binder matrix. The shaped abrasive composites include a bottom surface and a top surface opposite and not contacting the bottom surface, and at least three sidewalls abutting both the bottom and top surfaces and two other sidewalls. In one embodiment, at least two cusps are formed by the top surface and individual sidewalls. In another embodiment, the top surface includes at least two triangular facets that contact at least two respective sidewalls and at least two cusps. The top surface includes at least one interior recessed portion nearer the cusps than the bottom surface. Methods of abrading a workpiece using the structured abrasive article are also disclosed.

Abstract: The method generally involves the steps of filling the cavities in a production tool each with an individual abrasive particle. Aligning a filled production tool and a resin coated backing for transfer of the abrasive particles to the resin coated backing. Transferring the abrasive particles from the cavities onto the resin coated backing and removing the production tool from the aligned position with the resin coated backing. Thereafter the resin layer is cured, a size coat is applied and cured and the coated abrasive article is converted to sheet, disk, or belt form by suitable converting equipment.

IPC: B24D11/02
Abstract: The present disclosure provides an abrasive article (10). The abrasive article (10) has a direction of use, a y-axis and a z-axis orthogonal to the y-axis and the direction of use. The abrasive article (10) further includes a backing (12) and shaped abrasive particles attached to the backing. About 5% to about 100% of the shaped abrasive particles (14) independently include a first side surface (16), a second side surface (18) opposed to the first side surface (16), a leading surface (20) connected to the first side surface (16) at a first edge (24) and connected to the second side surface (18) at a second edge (26), a rake angle (30) between the backing (12) and the leading surface (20) in a range of from about 10 degrees to about 110 degrees, and a z-direction rotational angle (50) between a line (52) intersecting the first edge (16) and second edge (18) and the direction of use (22) of the abrasive article (10) in a range of from about 10 degrees to about 170 degrees.

Abstract: Methods of making abrasive articles involve adhering shaped abrasive particles to a reinforcing member according to a predetermined pattern and optionally orientation, and depositing a space-filling binder precursor on the reinforcing member and shaped abrasive particles to provide a filled abrasive preform, disposing another reinforcing member onto the filled abrasive preform, and curing the abrasive article precursor to form the abrasive articles. In some aspects, multiple abrasive preforms are stacked on each other. Bonded abrasive wheels preparable according to the methods are also disclosed.
