Ballscrew Thickness!

[ptjw7uk]

If the problem with long ballscrews is whip why not fit traveling intermediate bearings as in travelling steady would only need a bearing in which the ballscrew would slide and then some sliding mechanism to pull the steady back into place when the axis moved to the other end. t least 2 steadies would be needed each side (if double ballscrews) plus space at each end to park the steady.

Just an idea!

You would still have a bit of chatter and vibration and i think the cost of this would also be more than the cost of a larger ball screw.

It's only circumventing a bad design.
