Pneumatic numerical control threading machine

The invention provides a pneumatic numerical control threading machine, and relates to the technical field of threading machines, the pneumatic numerical control threading machine comprises an adaptive control assembly, a mounting shell is inserted in a mounting base, and the adaptive control assembly can automatically control the machining state of a machining assembly, that is, the rotating speed and torque of a threading cutter head during machining can be controlled; therefore, the device can automatically change the machining rotating speed and the machining torque of the threaded cutter head according to the material of a machined workpiece, can automatically switch to a low-speed and high-torque machining mode according to actual machining requirements when the workpiece made of a hard material is machined, and can stably machine and use workpieces made of different types of materials; the problems that according to an existing threading machine, the corresponding machining force cannot be adjusted according to the material of a workpiece, and when threads are machined on a hard workpiece, tapping is difficult, so that a machining motor is prone to heating and is damaged and burnt down are solved.
