1. A diamond special-shaped grinding wheel, comprising:
an upper base body,
a lower base body, and
a grinding ring,
wherein the upper base body is arranged at an upper end of the lower base body, and the upper base body and the lower base body are fixedly connected to form a grinding wheel body;
wherein the grinding ring in an annular shape is fixed to an outer circular ring of the grinding wheel body;
wherein the grinding wheel body is internally provided with one or two annular grooves communicated with an upper end face of the grinding wheel body;
wherein a plurality of mixed flow channels through which cooling water, powder and air are sucked is formed in the grinding ring;
