I'm assuming that whoever machined that part either used a horizontal swiss type cnc lathe, or a 3 axis vertical milling machine with an A axis mounted table. also a part like that doesn't have an extremely hight tolerance space, I'm used to alot more, where the part has to be within 300 thousands of the original, but nonetheless it is a precision part. I'm curious of whether the main part of the internal shaft, is that created of a single piece of material?, or is a couple threaded together?
