Ballscrew Thickness!

[Ross77]

Gary (from Zapp) gave me a website which allows you to calculate the whip speed based on the diameter and so forth

As Tribbles said the diameter required to reduce whip is fairly easy to work out. The pitch is not so. You mentioned speed and accuraccy..... I dont think the two are easily achived without lots of money.......

You havent said what you are cutting or what accuraccy you require. But if you are using steppers when 200 steps per rev at 5mm pitch gives 0.025mm resolution. With a 25mm pitch you get 0.125mm resolution.

Also given that for your 1829mm travel you will probably need 20mm + dia. then motor torque will be an issue, lots of mass and inetia to control.
I may be corrected by others but you are probably in Servo Motor terratory for the distances and speeds you require.

See the attached pdf that I got from Cnc-zone.( hope its ok to repost it. cant remember who its from. {Lee any probs just remove it}

Goes in to detail about designing motors, screws and feeds.
