Fellow machinists, I am trying to buy a new CNC lathe. Factory default chuck is Samchully 8" 3-Jaw with A2-5 mount. I live in an area where we have plenty of machine shop auctions / surplus, and I figured I may be able to find decent second hand chucks and save money. In your experience, is this worth doing? I am not sure how to tell if a used chuck's best days are behind it in the settings I get to see them sitting on a wooden pallet.
