The polishing pad stack also includes a compressive subpad with a first surface having a first pressure sensitive adhesive layer coated thereon. The first surface of the compressive subpad is coupled directly to the back surface of the polishing pad by the first pressure sensitive adhesive layer.

A wheel brush (1) includes a grinding element bundle holder (3) having an annular grinding element bundle-holding surface (12) that faces the outer circumferential side and a plurality of grinding element bundles (4) that are formed by gathering a plurality of wire-shaped grinding elements (5). The grinding element bundle-holding surface (12) has a plurality of holding holes (16) arrayed in a circumferential direction (R), the grinding element bundles (4) protrude to the outer circumferential side from the grinding element bundle-holding surface (12) while one end portions are inserted into the holding holes (16). First protrusions (18) protruding to the outer circumferential direction are provided on first opening edge portions (17a) adjacent to the holding holes 16 at a first direction (L1) side in the rotational center line direction orthogonal to the circumferential direction R (R) in opening edges of the holding holes (16) in the grinding element bundle-holding surface (12). The first protrusions (18) are continuous in the circumferential direction R (R) to configure an annular first flange portion (19).

A system includes a distribution tool, a backing, a first plurality of abrasive particles and a second plurality of abrasive articles. The distribution tool includes a first section and a second section. The first section is configured to receive the first plurality of abrasive particles and pass the first plurality of abrasive particles through one or more of the plurality of slots to the backing. The second plurality of abrasive particles differ in at least one of a size, an average weight and a shape from the first plurality of abrasive particles. The second section is configured to receive the second plurality of abrasive particles and pass the second plurality of abrasive particles through one or more of the plurality of slots to the backing.

An open coat abrasive article includes a backing having first and second opposed major surfaces, a make coat resin on at least one major surface of the backing, abrasive particles arranged on the backing at least partially embedded in the make coat resin, and a size coat resin on the first resin and the abrasive particles, wherein the shaped abrasive particles have an average peak count of no greater than about 40,000 per 24 in.sup.2. A method of abrading in a body-in-white application is also disclosed.

An apparatus and method for transferring particles by the use of a transfer tool to at least a portion of which is applied a vacuum to cause particles to jump from a particle source to the transfer tool.

An abrasive article comprises abrasive particles secured to a substrate by at least one binder material. The at least one binder material comprises a cured reaction product of components comprising: a) at least one phenolic resin; and b) an aqueous dispersion of at least one polyurethane, wherein, based on the total solids weight of components a) and b), the components comprise 56 to 91 percent by weight of component a) and 44 to 9 percent by weight of component b). Methods of making and using the abrasive articles are also disclosed.

Object: To provide a grinding wheel and a method of manufacturing a grinding wheel having added value while providing a suppressed manufacturing cost. Solution Means: The grinding wheel is a grinding wheel including an abrasive portion including nonwoven fabric, wherein the abrasive portion includes an outer peripheral portion formed with the nonwoven fabric including abrasive grains on an outer peripheral side, and an inner peripheral portion formed with the nonwoven fabric not including the abrasive grains, and a ratio of a thickness in a radial direction of the outer peripheral portion to a thickness in a radial direction of the abrasive portion is from 3% to 60%.

The present disclosure provides a shaped abrasive particle. The shaped abrasive particle includes a plurality of polygonal faces bound by respective polygonal perimeters and joined by at least one edge or sidewall to form the shaped abrasive particle. The shaped abrasive particle further includes a serration configured to generate a fracture along a fracture plane extending at least through the serration.

The disclosure relates to, among other things, a method of making a coated abrasive article, the method comprising sequentially: locating a plurality of shaped abrasive particles in a tool comprising a plurality of cavities, wherein the plurality of shaped abrasive particles is held in the plurality of cavities, at least in part, electrostatically; and disposing the plurality of shaped abrasive particles onto a make layer precursor of a backing having first and second opposed major surfaces, wherein the make layer precursor is disposed on at least a portion of the first major surface.
