The utility model discloses a closed protective cover for a precision numerical control surface grinding machine, which relates to the technical field of closed protective covers for surface grinding machines and comprises a protective cover body, symmetrical noise reduction mechanisms are arranged in the protective cover body, and each noise reduction mechanism comprises two fixing grooves. The two fixing grooves are fixedly connected to the inner wall of the protective cover body, a sound absorption plate is slidably connected between the two fixing grooves, the interiors of the two fixing grooves are slidably connected with a set of limiting rods, each limiting rod is slidably connected with the sound absorption plate, and fixing pads are arranged on the exteriors of the two fixing grooves. According to the noise reduction protective cover for the surface grinding machine, through cooperative arrangement of the protective cover body and the noise reduction mechanism, noise generated when a worker uses the
