Thread milling is mainly used for the processing of large-hole threads and threaded holes of difficult-to-machine materials. It mainly has the following characteristics:
(1) The processing speed is fast, the efficiency is high, and the processing precision is high. The tool material is generally cemented carbide material, and the cutting speed is fast. The tool is manufactured with high precision, so the thread milling precision is high.
⑵ Milling tools have a wide range of applications. As long as the pitch is the same, whether it is a left-handed thread or a right-handed thread, one tool can be used, which is beneficial to reduce tool costs.
(3) Milling is easy for chip removal and cooling. Compared with taps, the cutting performance is better. It is especially suitable for threading of difficult-to-machine materials such as aluminum, copper, and stainless steel, especially for large parts and parts of precious materials. Guarantee the quality of thread processing and the safety of the workpiece.
⑷ Because there is no tool front guide, it is suitable for processing blind holes with short threaded bottom holes and holes without undercuts.
