It could be big bore lathe of double chucks at both sides of the headstock, or it could have large swing for big workpiece. Big bore lathe is very good at threading and cutting at the two ends of long pipes or tubes. Besides, large swing could be applied to big steel rollers, large diameter flanges, long shafts of ships, etc. By the way, for better workpiece clamping, we have rotary quill option on tailstocks.
