High-precision numerically-controlled rotor grinding machine

The invention discloses a high-precision numerically-controlled rotor grinding machine which comprises such components as a machine body, a workbench, a head frame, a tail frame, a grinding wheel rack, a precision grinding tool and a grinding wheel mechanism; the machine body adopts a numerically-controlled forming grinding method, a mathematical model that the motion trail of a trimming roller is conjugate with a forming surface is established, and the movement of two shafts of a grinding wheel dresser is controlled through a numerical control device to enable the arc center of a diamond roller to generate linkage in two coordinate directions, and the grinding wheel is dressed into a required forming surface. During processing, the grinding wheel is fully contacted with the outline of a workpiece, and numerically-controlled forming grinding is realized by utilizing lengthwise movement of the workbench, precision indexing movement and transverse feeding movement of the grinding wheel, so that a rotor can be g
