Hey Gang – Looking for some input on a smart way to make this print in quantities of 25-50 at a time, several times a year, with a manual lathe and VMC with a 5C indexer as a 4th axis. Material is 1018, nothing crazy on any of the tolerances: ±.005” general, two smallest ODs are ±.002” and need to be concentric within .002”
I can think of a couple different approaches, but at some point in each of them I wind up saying to myself “there’s got to be a better way to do that.”
If I turn it down from round and part it off to length, I don’t have anything to hold onto to cut it in half with a slitting saw. And then I don’t have anything to hold onto to put the c’bores and tapped holes in the one side.
If I turn it down from round, part it off long so I have something to hold, put it in the 5C for the mill work and slitting saw, I can pull it out, clamp it with a spacer in and mill the opposite side to length, but that’s a lot of hands-on fussing.
Even if I had a live-tool CNC lathe (turn to size/shape, live tool c’bores and tapped holes, live tool slitting saw) then I’m left with an interrupted cut parting off, which I wouldn’t like. But it’s a moot point, since I don’t have that lathe.
I have a feeling this is one of those situations where I’m missing the obvious solution, so another set of eyes on it would be appreciated.
Thanks all!
