What is Ball Screw Accuracy and Why is it Important?

2014-07-23  Ball screws are used because they allow closer tolerances than standard types of screw assemblies and with lower friction due to the use of ball bearings. But they still need to be correctly designed and engineered in order to ensure acceptable levels of accuracy when used in a CNC mill.

Value of Bridgeport mill ball screws?an - Practical Machinist

2017-12-21  I have rolled ball screws on my big Webb mill. They were on there when I got it because the machine was originally set up for CNC. All that is necessary to avoid back feeding is to use the table locks. The Webb has two of them on the X and one on the Y and it's a simple matter to use them. My machine is a 1987 and it saw a lot of use before I got it and it's still got zero lash on the Y axis ...
