CNC thread milling method
In the process of CNC machining, there is a method called thread milling. What is it? CNC thread milling is a milling method which uses thread milling cutter, machining center three-axis linkage, namely x, Y axis arc interpolation, Z axis linear feed.
Thread milling is mainly used for large hole thread and difficult to machine material thread hole. It has the following characteristics:
(1) high processing speed, high efficiency and high processing precision. The cutting tool is made of cemented carbide, and the cutting speed is fast. Therefore, the precision of thread milling tool is high.
(2) milling tools are widely used. As long as the pitch is the same, whether it is * * thread or right-hand thread, a tool can be used, which is conducive to reducing the cost of the tool.
(3) milling is easy to remove chips and cool, and the cutting condition is better than tap. It is especially suitable for thread machining of difficult to machine materials such as aluminum, copper and stainless steel,
Especially suitable for large parts and valuable material parts of the thread processing, to ensure the quality of thread processing and workpiece safety.
(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.
