In CNC milling, when each tooth is uneven, discontinuous cutting, hard air conflict and vibration during cutting and cutting; the cutting layer parameters and cutting force are changed during milling, and it is easy to cause vibration and affect the processing quality; Cnc CNC milling machine is developed on the basis of general milling machine. The machining process of the two is basically the same, the structure is similar, but the cnc CNC milling machine is automatically processed by program control. Machine tool, so its structure is also very different from ordinary milling machine. CNC milling machine and machining center are the same reason, it is mainly used for boring holes with relatively large diameter.

CNC milling machines are generally used to mill relatively simple surfaces, as well as to mill shallow holes. The structure of the CNC milling machine is horizontal, and the bed structure of the CNC milling machine is vertical and generally small. The CNC milling machine has a tool magazine that can automatically change the tool. The number of milling machines has no tool magazine, and the tool change is manually performed during the machining process. At present, the CNC milling machine and machining center are basically versatile, but the trampoline is limited in machining parts. As for programming, the drilling of the boring machine is generally carried out per revolution, while the machining center generally feeds every minute. The boring and milling machine has better centripetal force, and the ram can extend very long. It is generally used for machining box parts with high precision and large volume. Cnc CNC milling machine bed shank is relatively stable, and the surface precision is relatively high. The center can basically be realized. CNC milling is the application of cutting machines with milling cutters: machining surfaces (horizontal planes, vertical surfaces, etc.), grooves (keyways, T-slots, dovetails, etc.). Cogging of multi-tooth parts (gears, Sprocket, ratchet, spline shaft, etc.), threaded surface (thread and spiral groove) and various curved surfaces.
