Thread: Rotating Ball nut
Threaded View
-
08-03-2013 #19I'd be wary of compromising rigidity for weight at all. It's much more important to have a strong machine than a fast machine.
Well, I had one ballscrew that was very bent, of course when I bought them they were all packaged up, so it was hard to see that they could have been bent. I've managed to straighten the worse one almost completely, but am awaiting loan of a friends press to enable me to straighten it further. I'm wondering if I could get the ballscrews under tension whilst on the machine by tightening both ends, and hopefully pulling it straight?
