The invention provides a numerical control machining machine tool. The numerical control machining machine tool comprises a supporting base, a machining machine head, a cutter base, a plurality of nozzles, and a collecting device which is used for collecting cutting bits. The cutter base slides relative to the machining machine head in the vertical direction and rotates with the cutter base as the rotating axis. The nozzles are arranged on the machining machine head. The collecting device comprises an annular collecting baffle surrounding the supporting base. The height of the annular collecting baffle is larger than that of the supporting base. A collecting cavity is formed between the annular collecting baffle and the supporting base. The collecting cavity is internally provided with a conical cutting bit collecting filter net. A cooling liquid collecting trough is formed in the bottom of the collecting cavity. The cutting bit collecting filter net is arranged above the cooling liquid collecting trough. Removing mechanisms used for removing cutting bits on the surface of a machined workpiece are arranged on at least two sides of the annular collecting baffle. A bit stacking mechanism used for stacking cutting bits is arranged above the cutting bit collecting filter net. The cooling liquid collecting trough and a cooling liquid recycling mechanism are connected. The cutting bits can be removed conveniently, and cooling liquid can be recycled.
