摘要： A grindstone that enables grinding, polishing, super-finish polishing by using the same grindstone, without clogging even if the grindstone is being used continuously, in which a grinding/polishing section for processing a workpiece has a honeycomb structure formed by arranging polygonal prisms with no clearance therebetween. The grindstone includes the grindstone columns consisting of abrasive grains and binder and having an axis in depth direction of grinding/polishing surface, which are disposed on intersections or wall portions of the honeycomb structure. Porous elastomer is disposed inside the honeycomb structure, thus making it possible to perform a super-finish polishing.

摘要： Interrupted structured abrasive articles comprise an abrasive layer comprising shaped abrasive composites that extend outwardly from a first major surface of a backing to which they are secured. The abrasive layer defines at least one open region that is free of the shaped abrasive composites and may extend partially or completely through the backing. In some embodiments, each of the open regions comprises a circular area of at least 1.5 square centimeters, and when combined the open regions have total area that is at least 10 percent of the area of the first major surface of the backing. Interrupted abrasive articles are useful in single-sided polishing processes.

摘要： A double-disc straight groove cylindrical-component surface grinding disc, includes a first grinding disc and a second grinding disc, rotating relative to each other; the the first grinding disc's working face is planar; the second grinding disc's surface, opposite the first grinding disc, includes a set of radial straight grooves, with groove faces of the straight grooves are the working face of the second grinding disc; the cross-sectional outline of the working face of the second grinding disc is arcuate or V-shaped or is a V-shape having an arc; during grinding, a workpiece spins inside the straight grooves, while under the effect of an advancing apparatus, the workpiece slides in translational motion along the straight grooves. The described grinding disc device has high-volume production capabilities, and the shape accuracy and size consistency of the cylindrical roller's cylindrical surface and the efficiency in machining are improved, and machining cost is reduced.

摘要： A coated abrasive article includes a backing having a surface, a plurality of abrasive regions overlying the surface in each of the first and second portions, and at least one macro-channel. The surface of the backing has a shape defined by an outer contour. A bisecting axis divides the shape into first and second portions. Each abrasive region includes a binder and a plurality of abrasive grains in contact with the binder. The abrasive grains have an average grain size of not greater than about 200 microns. The at least one macro-channel defines a passageway extending between a pair of adjacent abrasive regions and terminating at openings at the outer contour within each of the first and second portions. The macro-channel has an average channel width of between about 0.1 millimeters to about 5 millimeters and is substantially free of the binder and the abrasive grains.
