Any CNC lathe with a bar feed could knock out the part bore and
chamfer with maybe a 30 second cycle time. No need to build a special
machine.

My *guess* is pre sltting would not be any easier and would slow down
the CNC lathe work.

I did talk to a guy that make CNC parts for me and he doesn't want to
deal with the plastic swarf.


I've not done 10K parts but I found a shop vac to work real well for
plastic swarf. Maybe you don't want to go there, but this might be a
good time to buy your first CNC lathe.
