摘要： PROBLEM TO BE SOLVED: To provide a soft touch in use and polish a work without damage by arranging inorganic long fibers in the rotating axial direction, and setting the bending strength and bending elastic modulus to specified values, respectively. SOLUTION: Inorganic long fibers 1 are arranged in the rotating axial direction, and bending strength and bending elastic modulus are set to 450 Mpa or more and 50 Gpa or more, respectively. Such a polishing rotary tool can be obtained, for example, by neatly arranging the organic long fibers 1 in a proper alignment direction to form a bar-like fiber bundle 2 or braided body, and bonding it by a matrix resin 4 into an optional form. In this manufacturing process, a matrix resin containing abrasive grains 3 is used as the matrix resin 4, whereby this tool can be easily manufactured. According to this structure, a soft touch can be provided in use, and a work can be polished without damage. The tip of the rotary tool can be machined into an optional form according to the shape of the work.

摘要： PROBLEM TO BE SOLVED: To eliminate the loading while improving rigidity so as to prevent the generation of breakdown during the use by including a specified wt.% of abrasive grains in the resin matrix, and setting the bending strength and bending elasticity at a specified value or more. SOLUTION: A grinding rotary tool is obtained by impregnating the matrix resin 4 including the abrasive grains 3 in fiber bundle 2 of the inorganic long fibers 1 having a circular cross section and aligned into the bar-like shape, and hardening it. Cross sectional shape of the rotary tool can be formed into a desirable shape such as an elliptic shape, triangle shape, square shape, hexagonal shape, besides a circular shape. Quantity of blending of the abrasive grains is necessary to be restricted to a small quantity such as about 20 wt.%. Bending strength of this rotary tool is set at 450 Mpa or more, and bending elasticity thereof is set at 50 Gpa or more. As a resin matrix, thermosetting resin such as phenol resin, epoxy resin, polyimide resin, polymaleimide resin, unsaturated polyester resin is desirably used.
