Numerical control machine tool with active protection

The invention relates to the technical field of numerical control machine tools, and particularly discloses a numerical control machine tool with active protection, which comprises a machine tool body, a mounting compartment and a base station are respectively arranged on two sides in the machine tool body, a three-jaw chuck is arranged on the mounting compartment, and a moving table with a cutter head is arranged on the base station; the rotary driving mechanism is used for driving the three-jaw chuck to rotate; the separating mechanism is used for separating the rotary driving mechanism from the three-jaw chuck; and the anti-splashing mechanism is used for wrapping the three-jaw chuck and the cutter head. When a cutter is collided, the sliding ring slides into a sensing area of the sensor under the inertia effect, a trigger signal is generated, the synchronous belt and the driving belt wheel are separated immediately through the separating mechanism, a torque transmission path between the driving motor and
