Full-automatic high-precision composite numerical control machine tool

The invention relates to the technical field of numerical control machine tools, and discloses a full-automatic high-precision composite numerical control machine tool which comprises a machining platform, a protective shell, a noise reduction interlayer, a connecting structure, a pushing plate and a pushing structure, a sliding structure is arranged on one side of the machining platform, the pushing structure is arranged on the other side of the machining platform, and the protective shell is arranged on the upper surface of the machining platform. According to the application, the noise reduction interlayer and the connecting structure are arranged, the noise reduction interlayer is of a porous structure, noise is adsorbed, external noise is reduced, when the noise reduction effect is poor due to the fact that the noise reduction interlayer is aged, a pull rod is released after a new noise reduction interlayer is installed in place by a user, and the pull rod pushes an embedding plate to reset under the ela
