A specialized machine for machining connector pins, like a cam lathe, automatic lathe, or something like that. I asked the master to do centering machine they said these have a special machine

To do this kind of workpiece machine tool is relatively simple, more sub-processes, most of the automatic lathe, automatic punching machine, automatic milling machine, polishing machine and other automated equipment to do. Processing costs should not be very high. If you know the technology, you can do processing, not very understanding or the amount is not very large if sent out to others to do more worry.
