CNC milling/lathe machines come in a variety of sizes. and can manufacture shafts as small as 1mm to shafts as long as 40ft(well, at least thats the largest i have seen)...
we use CNC to grind rolls(paper industry)... good thing about this is you only have to feed your specs and the machine does the rest in extreme precision....
