The invention discloses a composite grinding wheel for super-speed grinding. The composite grinding wheel comprises a grinding wheel substrate, a binding agent layer and a grinding material layer and is characterized in that the grinding wheel substrate is composed of a metallic framework and a composite coated body; the metallic framework comprises a hub, a rim and a radial plate which connects the hub and the rim; at least three mounting holes located in a same circle are formed in the hub; the composite coated body is arranged between the hub and the rim and integrated with the radial plate; the binding agent layer and the grinding material layer are arranged on the outer surface of the rim. According to the grinding wheel, super-hard grinding materials are connected with the substrate in a high strength mode through a high-frequency induction brazing process, and the grinding speed can reach more than 200m/s.
