Hardware knowledge: use value and processing method of thread milling cutter

The traditional thread processing method is mainly to use thread turning tool to turn the thread or use the tap and die to manually tap and buckle. With the development of CNC machining technology, especially the emergence of three-axis linkage CNC machining system, the more advanced thread machining method CNC milling of thread can be realized.

Compared with traditional thread processing methods, thread milling has great advantages in processing accuracy and processing efficiency, and it is not restricted by thread structure and thread rotation during processing. For example, a thread milling cutter can process a variety of different Internal and external threads in the direction of rotation. For the thread that does not allow transitional buckle or undercut structure, it is difficult to machine using traditional turning methods or taps and dies, but it is very easy to achieve by CNC milling. In addition, the durability of thread milling cutters is more than ten times or even dozens of times that of taps, and in the process of CNC milling threads, it is extremely convenient to adjust the size of the thread diameter.
