CNC Milling Thread Technology and Tapping Thread Technology

CNC Milling Thread Technology and Tapping Thread Technology

With the gradual maturity of CNC thread milling technology, it has been applied to drilling and thread milling of aluminum alloy, stainless steel and other materials. Compared with traditional tapping methods, milling thread Machining has many advantages.

1. Compared with the kneading process of tapping, the surface quality of high-speed milling is better.

2. Program interpolation can be easily adjusted to make the dimension accuracy of threads higher, especially in the fine thread machining occupies a positive advantage.

3. Good stability, safety and reliability. In tapping process, if the tap is broken in the workpiece, electrical pulse is needed to break the tap. It is very likely that the workpiece will be scrapped because the tap can not be removed. In milling thread, if the thread milling cutter is broken, the machining process is very simple, thus reducing the scrap rate caused by similar reasons to zero.

4. CNC milling threads have more advantages in large diameter (larger than M25), small diameter (smaller than M2), blind hole and deep hole threads.

5. Machining costs are lower.

6. CNC milling can finish threading of difficult-to-machine materials (such as stainless steel, titanium alloy, etc.) more easily, and the machining power and function are better than tapping method.
