Abstract
A process for producing a polyurethane grinding tool is provided, the process including a step of mixing one or more types of polyol component selected from the group consisting of polyether polyols and polyester polyols with inorganic abrasive grains, a step of mixing an organic polyisocyanate component with inorganic abrasive grains, a step of uniformly mixing the polyol component mixed with the abrasive grains and the polyisocyanate component mixed with the abrasive grains by means of a rotary-static mixer, and a step of molding the mixture thus obtained by reacting the mixture in a mold.
