    摘要: To provide a nonwoven fabric polishing roll that can reduce the occurrence of polishing defects and carry out uniform polishing. A nonwoven fabric polishing roll having a through hole in to which a rotation shaft of a polishing machine is inserted, and the internal surface of the through hole engages with the rotation shaft so that the torque of the rotation shaft is transmitted, the nonwoven fabric polishing roll comprising: a plurality of circular nonwoven fabrics having an aperture in the center thereof that forms the through hole; and a plurality of circular plates having an aperture in the center thereof that forms the through hole, and having an outer diameter that is smaller than the outer diameter of the circular nonwoven fabric, wherein the plurality of circular nonwoven fabric and the plurality of the circular plates are stacked so that one or two or more of the circular nonwoven fabrics are sandwiched on their aperture side by the circular plates, and bonded together with adhesive while compressed in the stacking direction, and the compression deformation ratio of the circular plates with respect to pressure forces from a direction normal to the stacking direction is smaller than that of the circular nonwoven fabric.

    摘要: There are provided a method of manufacturing a grinding wheel in which abrasive grains and vacancies have prescribed densities and are uniformly dispersed, and a grinding wheel. After a first overcoat layer (2) is formed on each of CBN abrasive grains (1), a second overcoat layer (3) that is plastically deformed under a pressure lower than a pressure under which the first overcoat layer (2) is deformed is formed on the outer side of the first overcoat layer (2) to manufacture coated abrasive grains (4). The pressure under which the coated abrasive grains (4) are subjected to pressure-molding so as to be formed into a prescribed shape is equal to or higher than the pressure under which the second overcoat layer (3) is plastically deformed. Due the pressure application, the second overcoat layers (3) are deformed and flow to form a molded material (6) having a structure in which the first overcoat layers (2) contact each other and the flowing second overcoat layers (3) are moved into clearances between the coated abrasive grains (4). By sintering this, it is possible to manufacture a grinding wheel having a structure in which the CBN abrasive grains (1) are dispersed at prescribed distance that is determined by the degree of outer radius of each first overcoat layer (2) and vacancies are arranged therebetween at a prescribed density.
