[0002] Numerical control machine tools are a type of automated machine tool equipped with a program control system that can logically process programs defined by control codes or other symbolic instructions.

[0003] CN220680189U discloses "A High-Efficiency CNC Machine Tool", which includes a machine tool. A motor is fixedly connected to the front of the machine tool, and a screw is fixedly connected to the output end of the motor. A movable block is threadedly connected to the surface of the screw, and a fixed plate is fixedly connected to the bottom of the movable block.
