An abrasive article (100) comprising a backing (102); a make resin (112) contacting the backing (102); abrasive particles (114) contacting the make resin (112); and a size resin (116) contacting both the abrasive particles (114) and the make resin (112), wherein the make resin (112) includes an alkyl quaternary ammonium clay, which can take the form of Garamite.

A composite coating is provided for a tool. The tool can be a pair of scissors or a screwdriver for example. The tool is made with at least one contact face. The composite coating includes diamond grains and layer of metal oxidant. The metal oxidant is used as catalyst to secure the diamond grains to the contact face.

An abrasive article is provided that may include a body. The body may include a bond component and abrasive particles within the bond component. The bond component may include a FeCoCuNiSn based bond material and a performance enhancing material. The performance enhancing material may include hex-boron nitride. The content of the performance enhancing material may be at least about 6 vol. % and not greater than about 14 vol. % for a total volume of the bond component.

Various embodiments disclosed relate to an abrasive article. The abrasive article includes a metallic matrix component, an abrasive particle component dispersed within the metallic matrix component; and a filler particle component dispersed within the metallic matrix component. A portion of the filler particle component is at least partially coated by a first metallic layer. Additionally, a hardness of the abrasive particle component is greater than a hardness of the filler particle component

An abrasive article includes a backing, abrasive particles secured to the backing, and a size coat provided over the abrasive particles, the size coat comprises a binder resin, at least one filler material and at least one lubricant material having a melting temperature of at least about 200 degrees F. A method of grinding aluminum using such an abrasive article is also described.

With a method for the production of a grinding tool, a tool base body is provided, which configures a three-dimensionally shaped adhesive sur-face by application of a bonding agent. The tool base body is positioned in a way that the adhesive surface is arranged in an electrostatic field, be-tween a first electrode and a second electrode. Into the electrostatic field, abrasive grains are introduced, which, due to the electrostatic field, move towards the adhesive surface and adhere to same. The grinding tool produced in this manner has a three-dimensionally shaped abrasive grain layer. The production of the grinding tool is simple, flexible and economical. The grinding tool has a randomly shaped abrasive grain layer and can be applied in a manifold manner with a high cutting performance and a long service life.

A mirror finishing method for forming a mirror surface on a workpiece with a mirror finishing tool including a conically shaped cutting tool made of polycrystalline diamond or cubic boron nitride that is attached to a distal end of a shank, performs mirror polishing by abutting a conical surface of the cutting tool against a machined surface of the workpiece with the shank tilted with respect to the machined surface of the workpiece.

A method for producing a coated abrasive includes producing or providing an intermediate abrasive product that comprises a substrate, a plurality of abrasive grains that are bonded to the substrate, and at least one layer of an uncured size coat that at least partially covers the abrasive grains with the uppermost size coat being uncured. The method further includes applying at least one grinding additive to the uppermost, uncured size coat with the grinding additive applied to the size coat in dry form. The method also includes curing the uppermost size coat. A coated abrasive is produced by the method and the coated abrasive is used to process a surface.
