Hi
I have a small wood mill that I am trying to expand in one direction. The current ball screws have a pitch of 0.2 (5 tpi). They are driven by Nema 23's with 250 oz-inch holding torque. I have no success finding a 6 foot 5 tpi (0.2 pitch) ball screw and nut with at least 5 foot of travel. I am asuming that I need a 1 inch diameter ball screw for regidity.
Failing finding the ball screw, can I use a lead screw, or perhaps a belt? Mabee a gear and rack drive. What are the benifiets and drawbacks of each?
