Abstract: An abrasive article comprises a porous substrate having openings extending through the porous substrate between first and second opposed major surfaces. An abrasive coating is disposed on only a portion of a first major surface of the porous substrate. The abrasive coating comprises a functional layer disposed on only a portion of a first major surface of the porous substrate, a make layer disposed on at least a portion of the functional layer opposite the porous substrate, and abrasive particles. The functional layer and the make layer independently comprise chemically crosslinked binders. The functional layer fully occludes a first portion the openings and does not fully occlude a second portion of the openings, which permits passage of abraded swarf through the abrasive article. Methods of making the abrasive article are also disclosed.

Abstract: An abrasive article includes a first plurality of abrasive particles and a second plurality of abrasive particles. The first plurality of abrasive particles differ in at least one of a size, an average weight and a shape from the second plurality of abrasive particles. The first plurality of abrasive particles are spaced from the second plurality of abrasive particles by at least a minimum distance in the x-axis direction, and both the first plurality of abrasive particles and the second plurality of abrasive particles extend in similar paths to one another with respect to the y-axis.

Abstract: An abrasive article is presented that includes a first set of shaped abrasive particles with a majority of the first set of shaped abrasive particles are oriented with respect to a backing in a first orientation. The abrasive article also includes a second set of shaped abrasive particles with a majority of the second set of shaped abrasive particles are oriented with respect to the backing in a second orientation, and wherein the second orientation differs from the first orientation. The first and second set of shaped abrasive particles are embedded within a coating layer on the baking.

Abstract: An endless abrasive belt dispenser (212) is disclosed and has a housing (222), a retaining element (224) and an actuating element (226). The housing (222) is configured to receive a plurality of endless abrasive belts (14) therein with the plurality of endless abrasive belts arranged as a stack. The retaining element (224) is moveable relative to a wall (230) of the housing (222) and is configured to hold the stack within the housing such that a first of the plurality of endless abrasive belts of the stack selectively contacts the first wall (230) and is generally aligned with an opening (216) of the housing. The actuating element (226) is moveable relative to the first wall (230) and retaining element (224) and is configured to selectively contact and move the first of the plurality of endless abrasive belts (14) relative to the first wall (230) and to the opening (216).
