I'd be real afraid of putting kinks in it with a press. For a 3/4" screw, I
think I could straighten the central part by hand. Possibly using some
rounded material in the center of a table, and pressing down at
both ends, and then moving the material around to even up the
bending. I have straightened some things with this method, but
never a ballscrew!
