Thread milling uses thread milling tools and three-axis linkage of the machining center, i.e. x-axis and y-axis arc interpolation, and z-axis linear feed to process threads.
Thread milling is mainly used to process large hole threads and threaded holes of difficult to machine materials. It has the following characteristics:
⑴ fast processing speed, high efficiency and high processing accuracy. The tool material is generally cemented carbide material, with fast tool walking speed. The manufacturing accuracy of the cutter is high, so the milling thread accuracy is high.
⑵ milling tools have a wide range of applications. As long as the thread pitch is the same, whether it is left-hand thread or right-hand thread, a tool can be used, which is conducive to reducing the tool cost.
(3) milling is easy to remove chips and cool, and the cutting condition is better than that of tap. It is especially suitable for thread processing of aluminum, copper, stainless steel and other difficult to machine materials,
It is especially suitable for the thread processing of large parts and components of valuable materials, and can ensure the quality of thread processing and the safety of workpiece.
(4) because there is no tool front-end guide, it is suitable for processing blind holes with short thread bottom holes and holes without undercut.
