I work in a heavy foundry, Our pattern shop has massive lathes but they're really old fashioned by comparison with the OP's machine!!
We make some pretty decent sized stuff (Up to580 tonnes), Here's a screw press we made, One of several that were used for pressing undercarriage parts and wing strut strengtheners for the A380 Airbus!
At that time it was the biggest screw press ever made, I think it ended up at 250t
I inspected in an aerospace machining plant specializing in large aluminium, hard steel and titanium parts for aircraft. Wing spars and ribs, landing gear trunnions, flap tracks etc. Almost a hundred union and another fifty non-workers in mismanagement. The only lathe we had was a manual metal lathe (16 x 40) that maintenance used for repairs. Everything was CNC mills. Forgings and plate came in at a ton or two and went out as finished parts at 100 to 200 pounds. The rest chips. Nothing we had was as big as that puppy of yours though. Okay maybe some egos.
