Proper ball screws have two nuts with a spring between them to take up almost all slop. My 1977 model Boston Digital CNC mill has about .0005-6" backlash due to large screws with spring loaded nuts. A friend spent a ridiculous effort and money to convert a good BP to ball screws and add CNC. He has .002" backlash.

1. Cylindrical Shell: The ball mill consists of a hollow cylindrical shell that rotates about its axis. The shell is usually made of steel, stainless steel, or rubber. 2. Liners: An abrasion-resistant material such as manganese steel or rubber typically lines the inner surface of the cylindrical shell to protect it from wear due to the grinding action.
