The present disclosure relates to saturated or primed abrasive article constructions containing an anti-loading composition which significantly reduces loading, is coatable, is durable, and is relatively inexpensive to manufacture. In particular, the use of the anti-loading compositions of the present disclosure as a size coat at least reduces if not eliminates the need for a supersize coat, while offering comparable if not superior performance and durability. The abrasive article further includes an anti-loading size layer comprising a size coat binder and wax at least partially disposed on the abrasive layer.

A grinding apparatus includes: a holding table for holding a workpiece thereon; a grinding unit including a grinding wheel for grinding the workpiece held on the holding table, the grinding wheel including a grinding stone made of abrasive grains and grains of photocatalyst bonded by a vitrified bonding material; a grinding water supply unit configured to supply grinding water to the grinding stone when the workpiece held on the holding table is ground by the grinding unit; and a light applying unit disposed adjacent to the holding table and configured to apply light to a grinding surface of the grinding stone while the workpiece held on the holding table being ground.

The present invention relates to a grinding aid as well as a grinding method. Further, the present invention pertains to a titanium dioxide particle with a layer comprising a grinding aid as described herein and the use of said titanium dioxide particle in various applications.

An abrasive tool, including an abrasive carrier (1) having a shaft (2) for connecting the abrasive carrier (1) to a driving device for rotatably driving the abrasive carrier (1) about a longitudinal axis (X) and having a core (3) connected to an axial end (4) of the shaft (2), and an abrasive article (15) having a surface (16) being circumferentially closed about the longitudinal axis (X) and enclosing a cavity (17) extending along the longitudinal axis (X), wherein the core (3) is accommodated at least partially in the cavity (17), and wherein the core (3) includes a material mixture which includes a plastic with a heat-conductive filler, wherein the plastic is foamed, and wherein the filler has a thermal conductivity greater than 35 watts per meter and per Kelvin.

Disclosed herein are polyurethanes useful for polishing layers, where the polyurethane is a polyurethane having a Schiff base. Also disclosed herein are polishing layers containing the polyurethanes, polishing methods that use the polishing layers, and a modification method including a step of converting the Schiff base into at least one functional group selected from an aldehyde group, a carboxylic acid group, a hydroxyl group, and an amino group.

Disclosed is a process for making a grinding wheel for the squaring of ceramic, formed by a support body and an abrasive ring. The process does not involve costly workings on the body and on the ring and produces a light grinding wheel which, therefore, is more practical to be handled by the handling machine.

Nonwoven abrasive articles comprise a nonwoven abrasive member having an overlayer composition comprising a fatty acid metal salt disposed thereon adjacent to a working surface. The nonwoven abrasive member comprises abrasive particles adhered to a fiber web by a binder. The abrasive particles may be exposed and/or the nonwoven abrasive member may have suitable frictional properties. Methods of making the same are also disclosed.

The present disclosure relates to an abrasive article construction containing an anti-loading composition which significantly reduces loading, is coatable, is durable, and is relatively inexpensive to manufacture. In particular, the use of the anti-loading compositions of the present disclosure as a size coat at least reduces if not eliminates the need for a supersize coat, while offering comparable if not superior performance and durability. In one aspect, the present disclosure provides an abrasive article including a backing with a first major surface and an opposing second major surface, an abrasive layer bonded to at least a portion of the first major surface, with the abrasive layer comprising abrasive particles retained in a make coat. The abrasive article further includes an anti-loading size layer comprising a size coat binder and wax at least partially disposed on the abrasive layer.

A gimbal for a conditioning system for a CMP tool is configured to maintain a conditioning disk in contact with a polishing pad of the CMP tool. The gimbal includes an arm coupling for coupling to a conditioning swing arm of the CMP tool; and a disk holder for holding the conditioning disk. A flexible diaphragm extends between the arm coupling and the disk holder. The flexible diaphragm allows the disk holder to flex relative to the arm coupling. The flexible diaphragm is made of a metal or metal alloy.

Abrasive articles, along with related compositions and methods, are provided. The abrasive articles include a backing, abrasive layer, and supersize coat that includes calcium stearate and an ammonium salt of a modified styrene acrylic polymer. The supersize coat can be dried to a translucent film at temperatures well below the melting temperature of the binder without need for a surfactant. Advantageously, these abrasive articles can reduce swarf accumulation during an abrading operation and enhance cut performance while achieving a high degree of optical clarity.
