The invention discloses a heavy-load numerical control rotating table which comprises a disc-shaped table, a rotating table body, a main shaft, a worm wheel frame and a worm gearing system, wherein one end of the main shaft is fixed on the rotating table body; the worm wheel frame is rotatablely connected with the main shaft through a main shaft bearing; the upper end of the worm wheel frame is fixedly connected with the table; a static locking system for locking the table is arranged along the circumference direction of the lower end surface of the table; and a plurality of damping dynamic vibration absorbing systems for eliminating the vibration of the table in cutting are arranged along the circumference direction of the lower end surface of the worm wheel frame. By arranging the static locking system and the damping dynamic vibration absorbing systems, the rigidity of the rotating table in both the static state and the dynamic state can be ensured, and simultaneously the working accuracy of an assorted host computer can be improved.
