An abrasive article including a substrate having an elongated body, a tacking layer overlying the substrate, and a first type of abrasive particle overlying the tacking layer and defining a first abrasive particle concentration at least about 10 particles per mm of substrate.

The disclosure relates to an abrasive article comprising: a fabric substrate comprising strands forming first void spaces between the strands; a laminate joined to the fabric substrate; a cured resin composition joined to the laminate opposite the fabric substrate; abrasive particles joined to the cured resin composition; and a plurality of second void spaces extending through the laminate coinciding with first void spaces in the fabric substrate. The disclosure also relates to methods of making such abrasive articles.

An abrasive article comprises abrasive particles adhered to a substrate by a binder material comprising an at least partially cured resole phenolic resin and an aliphatic tack modifier. The amount of resole phenolic resin comprises from 60 to 98 weight percent of the combined weight of the resole phenolic resin and the aliphatic tack modifier. A method of making the abrasive article is also disclosed.

A polishing pad comprising a textile layer, a compressible layer, and a water impermeable layer disposed between the textile layer and the compressible layer. The polishing pad reduces slurry use by improving slurry transport and requires no diamond conditioning to maintain slurry transport.

A grinding mechanism, in particular a grinding disc, for grinding a workpiece is disclosed. The grinding disc includes (i) a flexible support element, (ii) a plurality of grinding elements for grinding a workpiece, and (iii) a base binder element for arranging the grinding elements on the support element, in particular on a grinding side of the support element. The support element has a grinding region and, adjoining the grinding region, a free region which is in particular free from the, in particular each, base binder element. The grinding mechanism has an edge region which delimits an, in particular maximum, extension of the grinding mechanism and is free from a base binder element.

The invention relates to a coated abrasive tool including a carrier which has a carrier material and including an abrasive surface coating on a surface region of the carrier. The abrasive surface coating has abrasive functional particles and a thermoplastic binder for an adhesive connection between at least some of the abrasive functional particles and the carrier material. At least some of the abrasive functional particles on the surface region of the carrier are partly integrated into the carrier material and are connected to the carrier material, and at least some of the abrasive functional particles on the surface region of the carrier are additionally partly integrated into the thermoplastic binder, the thermoplastic binder being connected to the abrasive functional particles and the carrier material.

According to one aspect, an abrasive article includes a backing and an abrasive layer comprising shaped structures comprising abrasive particles and a binder, and an interlayer between the backing and the abrasive layer. The interlayer can have at least one of the following: an ILT.sub.ave of at least 4 microns, an ILT.sub.max of at least 5 microns, or an ILT.sub.min of at least 3 microns.

The disclosure relates to an abrasive article comprising: a fabric substrate comprising strands forming first void spaces between the strands; a laminate joined to the fabric substrate; a cured resin composition joined to the laminate opposite the fabric substrate; abrasive particles joined to the cured resin composition; and a plurality of second void spaces extending through the laminate coinciding with first void spaces in the fabric substrate. The disclosure also relates to methods of making such abrasive articles.

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.
