What is Thread Milling?

Thread Milling is a modern and efficient method of making threads with a milling operation.

For this you need a CNC-machine which can run in 3 directions at the same time. The thread is made with the circular ramping movement of a rotating tool. You can see this clearly demonstrated in the video “Advantage of Thread Milling”
