Abstract: A high-rotational speed cup-shaped grinding wheel includes an annular base, several blades and a flow splitting structure. The blades are fixed on a side of the base at an interval in a circumferential direction to form a blade ring. The side of the blade ring away from the base forms an annular working surface, and two adjacent blades are spaced apart from each other to form a water passage channel for delivering cooling water to the working surface. The flow splitting structure is fixed on the blade ring and splits the cooling water into two branches, where a first branch delivers the cooling water to an outer area of the working surface, and a second branch delivers the cooling water to an inner area of the working surface, and then delivers the cooling water from an inner area of the working surface to an outer side area thereof.
