摘要： The present invention relates to a poromeric article of manufacture comprising a felt sheet of fibers impregnated with microporous elastomer having a work surface, side surfaces joining the work surface and a support surface joining the side surfaces, wherein a majority of the fibers are oriented primarily transverse to the work surface such that the majority of fiber ends adjacent to the work surface form an angle of between about 45.degree. and about 135.degree. with respect to the work surface, and preferably, wherein the fibers have a uni-directional orientation substantially perpendicular to the work surface. The present invention also includes a plurality of such articles bonded together and oriented such that the work surfaces of adjacent articles are substantially coplanar to form a laminated article of manufacture. Further, processes for making the basic and laminated articles are set forth as other aspects of the invention.

摘要： A superhard polycrystalline construction comprises a body of polycrystalline superhard material comprising a structure comprising superhard material, the structure having porosity greater than 20% by volume and up to around 80% by volume. A method of forming such a superhard polycrystalline construction comprises forming a skeleton structure of a first material having a plurality of voids, at least partially filling some or all of the voids with a second material to form a pre-sinter assembly, and treating the pre-sinter assembly to sinter together grains of superhard material to form a body of polycrystalline superhard material comprising a first region of superhard grains, and an interpenetrating second region; the second region being formed of the other of the first or second material that does not comprise the superhard grains; the superhard grains forming a sintered structure having a porosity greater than 20% by volume and up to around 80% by volume.

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.
