The invention discloses a numerically-controlled machine tool. The numerically-controlled machine tool comprises a base. A first connecting plate and a second connecting plate are arranged on the base and are provided with through holes correspondingly. A motor spindle is arranged in the through holes. A C-shaft transmission base is arranged at one end of the motor spindle, and a spindle seat is arranged at the other end of the motor spindle. The spindle seat is arranged on the second connecting plate. A C-shaft servo motor, a C-shaft worm and a C-shaft worm wheel are arranged on the first connecting plate. The C-shaft worm is adaptive to the C-shaft worm wheel. The C-shaft servo motor is adaptive to the C-shaft worm which is adaptive to the C-shaft transmission base. An A-shaft servo motor, an A-shaft worm and an A-shaft worm wheel are arranged on the second connecting plate, the A-shaft worm is adaptive to the A-shaft worm wheel, and the A-shaft servo motor is adaptive to the A-shaft worm. The A-shaft worm wheel is arranged on the spindle seat and is adaptive to the motor spindle. The numerically-controlled machine tool has the advantages of being reasonable in structure design, stable in installation position, convenient to implement and good in transmission performance and precision.
