Through the comparison of various aspects, it can be found that there are many advantages in thread milling:
(1) A thread milling cutter can process threads with different diameters and the same tooth profile
Different threads can be processed with a thread milling cutter by changing the interpolation radius, which can reduce the number of tools, save tool change time, improve efficiency, and facilitate tool management; and one tool can process left and right-hand threads. Whether the thread milling cutter processes the thread left-handed or right-handed completely depends on the machining program.
(2) Improved thread accuracy and surface quality
Thread milling is completed by high-speed rotation of the tool and spindle interpolation. The cutting method is milling, the cutting speed is high, and the precision and surface quality of the processed threads are high.
(3) Convenient chip removal for internal threads
Thread milling belongs to chip-breaking cutting, and the chips are short and small. In addition, the diameter of the machining tool is smaller than that of the threaded hole, so the chip removal is smooth.
(4) Low power of the machine tool is required.
Because thread milling is chip-breaking cutting, the tools are in local contact and the cutting force is small, so the power requirement of the machine tool is low
(5) The reserved depth of the bottom hole is small
For threads that do not allow transitional threads or undercut structures, it is difficult to machine with traditional turning methods or taps and dies, but it is very easy to realize with CNC milling. Thread milling cutters can process flat-bottomed threads.
(6) Long tool life
The life of thread milling cutter is more than ten times or even dozens of times longer than that of taps. In the process of CNC milling threads, the adjustment of thread diameter is extremely convenient, which is difficult to achieve with taps and dies.
(7) It is easy to do secondary cutting of thread
The reprocessing of existing threads has always been a difficult problem in thread machining by turning. After the use of thread numerical control milling, this problem will be solved. From pure kinematic analysis, it can be seen that as long as the feed distance of each circle is fixed during milling, and the tool is cut from a fixed height each time, the machined threads will be at the same position, and the radius of the machine will be different. It will affect the thread depth (tooth height), so there is no need to worry about the occurrence of chaotic teeth.
