Abstract
PURPOSE:To shape a spherical isolated grain abrasives free from burring by clamping mixture composed of a grain and a liquid hardening high molecular compound binder at more than 2 of thixo index. CONSTITUTION:A mixture 4 composed of a grain and a liquid hardening high molecular compound binder (e.g. unsaturated-polyethylene resin, epoxy resin etc.) at more than 2 of thixo index fills a semiperipheral section 3 with a given diameter cut at the symmetrical position on the symmetrical surface of upper and lower molds 1 and 2. Then, the upper mold 1 is rotated to 180 deg. and combined with the symmetrical surface of the lower mold 2, pushed into a press 5 or the like. The upper and lower molds 1 and 2 combined tightly adhere to each other thereby leaking away the excess mixture from those other than the spherical section. Then, the mixture is hardened to produce a spherical isolated grain abrasives free from burring.
