Ballscrews? Anything like thumbscrews :-)

Seriously though, it seems that there's a lot of places for backlash
to build up in a screw-drive table, play in the nut, endplay in the
shaft itself, flex/springiness of the screw itself, etc.

Do modern machining centers still use screw drives? I wonder what the
alternatives are? Hydraulics? Linear motors? Acoustic wave motors?
