you tran,

You can use a ball screw, but you would need to use a brake to keep the Z
axis in place when you reduce the current on the drive.

Subject: [CAD_CAM_EDM_DRO] ball screw vs lead crew


> Hi,
> I have few questions to ask the group for help. Why do we only use ball
screws for X and Y axis and for Z we use lead screw? Are there ways that we
can use ball screws for all three axis? I have read many threads at
Cnczone.com on this subject but I still need help. Could some one help me?
Thanks
