In this video, you will see a Machining rack and angled gears on CNC milling machines for the operation we need a 4thaxis chuck in order to synchronize the rotation with the cutting pitch (module) and also a tailstock because the parts were long enough and also we check with the watch how homocentric is the rotation on the chuck and also on the tailstock.
