An abrasive tool can include a bonded abrasive including a body and a barrier layer bonded to a major surface of the body. The body can include abrasive particles contained within a bond material. The barrier material can include a metal-containing film. In an embodiment, the barrier layer may further include a polymer-containing film. In another embodiment, the barrier layer may include a biaxially oriented material. The abrasive tool may be formed such that the barrier layer is formed in-situ with the formation of the bonded abrasive.

A surface-treating article includes an organic matrix substantially engulfed by a binder that includes a reaction product of a blocked polyurethane prepolymer and a mixture of aromatic amines. The aromatic amines include polymethylene polyaniline having a functionality equal to or greater than 4.

A superabrasive material and method of making the superabrasive material are provided. The superabrasive material may comprise a superabrasive crystal having an irregular surface. The superabrasive material further comprises a plurality of structure defects within the superabrasive crystal. The plurality of structure defects may cause micro-chipping when used as grinding materials.

A flexible abrasive article is provided with a first, non-tacky base layer having opposed first and second major surfaces. An ink layer is disposed on the first major surface of the first base layer, while a second, thermoplastic base layer is disposed on the ink layer whereby the ink layer is located between the first and second base layers. Disposed on the second base layer is an abrasive layer such that the second base layer is located between the abrasive layer and the ink layer. Compared with conventional printed flexible adhesive articles, the provided articles improved robustness while avoiding manufacturing difficulties related to flexographic printing onto abrasive coated articles.

An abrasive body comprises portions of a first abrasive element. The portions of the first abrasive element are bonded ogether by a first binder material. The first abrasive element comprises abrasive particles bonded to a substrate by at least a second binder material. The portions of the first abrasive element are not agglomerate abrasive particles. The abrasive body has a maximum dimension, and the portions of the first abrasive element have a maximum dimension that is less than 80 percent of the maximum dimension of the abrasive body. A method of making an abrasive body is also disclosed.

A probe cleaning sheet for preventing a probe pin damage and manufacturing method thereof, during the process of a probe pin puncturing the cleaning layer, the material of the cleaning layer and the plurality of high and low density cleaning particles of abrasive material contained in the high density cleaning material and the low density cleaning material are able to efficiently scrape away foreign material from the surface of the probe pin. In addition, the negative charge carried by the silicone itself and its lipophilic characteristics are used to transfer the foreign material on the probe pin to the cleaning layer, and the protective layer is used to prevent overpressure from the probe pin directly impacting the substrate and causing damage to the tips of the probe pin.

A probe pin cleaning sheet with cleaning power and a manufacturing method thereof are disclosed, comprising a release layer, a cleaning layer, and a substrate. Thus, in the process that the probe pin pierces the cleaning layer, through the material of cleaning layer, and the cleaning grains of abrasive material contained in the cleaning material in the cleaning layer, the cleaning power is increased to scrape off dirt from the surface of probe pin. In addition, by the negative charges and lipophilic property of the silicone itself, the dirt on the probe pin can be transferred onto the cleaning layer.

An abrasive belt having a backing and an abrasive layer adhered to the backing by a make coat resin and the abrasive layer comprising a plurality of shaped abrasive particles. A first belt side and a second belt side opposing the first belt side with the first and second belt sides generally aligned with a longitudinal axis of the grinding belt. The belt having at least 30% of the shaped abrasive particles in the abrasive layer having a first face and placed onto the backing such that an angle between the first face and the longitudinal axis is greater than 0 degrees and less than or equal to 20 degrees.

The belt having at least 30% of the shaped abrasive particles in the abrasive layer having a first face and placed onto the backing such that an angle between the first face and the longitudinal axis is greater than 0 degrees and less than or equal to 20 degrees.

Coated abrasive articles having spacer particles are formed by providing a production tool having a dispensing surface with a plurality of cavities, guiding the production tool past an abrasive particle feeder, dispensing shaped abrasive particles onto the dispensing surface and into the plurality of cavities of the production tool, guiding a resin coated backing sheet adjacent the production tool past a spacer particle feeder, and dispensing spacer particles onto the resin coated backing sheet and/or the production tool after the abrasive particle feeder prior to a deposit point for the shaped abrasive particles. The spacer particles are selected to have a thickness that is greater than a thickness of a resin coating of the resin coating backing sheet and a thickness and density once dispensed that are sufficient to substantially prevent the production tool from contacting the resin coated backing sheet at the deposit point.
