摘要： A method of manufacturing a grinding wheel which includes a cylindrical core body and a plurality of part-cylindrical abrasive segment chips bonded to an outer circumferential surface of the cylindrical core body. The method includes: a firing step of firing an unfired part-cylindrical precursor to prepare each part-cylindrical abrasive segment chips, by using a supporting member whose coefficient of thermal expansion is different from that of each abrasive segment chip; and a bonding step of bonding the abrasive segment chips to the outer circumferential surface of the cylindrical core body with an adhesive interposed therebetween, by forcing each abrasive segment chip against the outer circumferential surface of the cylindrical core body, such that a force acting on the outer circumferential surface of the cylindrical core body is evenly distributed in an axial direction of the cylindrical core body while the adhesive is being hardened.

摘要： A disk-shaped grindstone including a base disk and an abrasive layer which is bonded to the base disk. The base disk is provided by a rapidly-solidified aluminum alloy whose major component is Si, wherein the rapidly-solidified aluminum alloy includes 15 wt %-40 wt % of the Si, 0.5 wt %-6 wt % of Cu, 0.2 wt %-3 wt % of Mg, and the balance consisting principally of aluminum. The ratio of a tensile strength of the base disk to a specific gravity of the base disk (tensile strength/specific gravity) is not smaller than 90. The ratio of a fatigue strength of the base disk to the specific gravity of the base disk (fatigue strength/specific gravity) is not smaller than 30.
