Ballscrew Thickness!

[Ross77]

Another Idea. :whistling: Have you thought about fixing the ballscrew and spinning the ballnut instead?

You would reduce the amount of torque needed as the mass is reduced. I have one like this that I got from ebay.

Finally why do you need so much speed? Unless it has to return home after along cut, wont you be limited by the cutting speed anyway?

I have seen this done before, but this normally involves more money and because the motor/gearing that is associated to this type is moving with the ball nut, the moving mass is higher.
