For the high-temperature alloy material threading, the thread cutter also shows very excellent processing performance and longer than expected long life, the same pitch, different diameter of the threaded hole, the use of tap, you need more tools to complete the processing, but if The use of a thread cutter, the use of a tool can be; in the tap wear, processing thread size is less than the tolerance, you can not continue to use, can only be scrapped, and due to thread cutter wear, processing screw hole size is less than the tolerance, System, make the necessary tool radius compensation adjustment, you can continue to process the size of qualified thread. Similarly, in order to obtain high-precision threaded holes, the use of thread cutter, adjust the tool radius of the method than the production of high-precision tap is much easier; for small diameter thread processing, especially in high hardness materials and high-temperature materials, The tap is sometimes broken, the threaded hole is cut, and even the parts are scrapped. The thread cutter is used. As the diameter of the tool is smaller than that of the machined hole, it will not clog the threaded hole even if it is broken. It will be easy to remove and will not cause the parts to be discarded. Thread milling, and tap compared to the tool cutting force greatly reduced, which is large diameter thread processing, is particularly important to solve the machine load is too large, can not drive the tap processing problems.
