They use tools we dream of, like drilling the blank, there are multi head drill presses that can drill a dozen blanks at once. It is also an automated system, the operator watches to make sure there are not malfunctions. The lathe cutter, is like a custom planer planer blade that the blank literally goes from a square to a completed turned blank. Sanding, theirs suck, again it is automated, a pre shaped sander drops on the cut blank and gets a hit lick and promise and moves to the next one.
You can speed up your own process by using production methods. Drill out 72 set of blanks at a time, then glue the 72 at a time, then turn the 72 and etc., etc.. The time it takes to switch tooling from drilling to turning is only a minute, but at 72 times that is an hour and 11 minutes of wasted time. Gluing? How much time does it take to get out the glue, and the get set up to glue tubes in? Even 30 seconds comes up to 35 minutes of wasted labor on 72 sets.
I could expand on that, but if you try it, you will soon feel like your penturning has become manual labor. Which if you are trying to make money, it is.
