I am way late to the party here-
Unless I am not seeing something in the drawing, I would say that you do not need CNC work on that part at all. Especially if the inside radius on the turned area is not a critical feature.
First setup the part in a manual mill with an indexer, drill your holes and do the counter bores. , then you can finish the turning operations on a lathe, probably do it between centers and at the end of the process, part off the smaller end.
If we made that in our shop and were only making a few of them, I would have our guys run it on manual equipment. If I were doing say, 50 or so, still stick with the lathe (depending on the tolerances and surface requirements) and do the holes and counterbores with a CNC simply because it would be easy to do them fast.
