How to tension a ball screw?
Steinmeyer | Ball Screw Technology Seems that it is more to do with thermal expansion than anything. I am going to presume that it also helps reduce whipping when under rapids. Belleville washers would be the best way to ensure a nearly constant force at all times. Our big bending machine has them installed.

How to use a tooling ball?
Tooling balls are really useful when you need to set work up on a sine plate. All of a sudden, all your references surfaces are gone, and the edges have turned into corners, which are inaccurate to pick up. If you had the foresight to install a tooling ball at a known location, you now have a point defined in all three axes to work from. Dennis

Ballscrew Upgrade
Adding the three ballscrews to the machine costs about $200 dollars. I got mine from a seller on ebay: Linearmotionbearings2008 Ebay Store . The nice thing about getting the ballscrew from the ebay seller was that he offers a machining service and will machine the ends of the ballscrews to your specifications.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Ball Mill Loading
The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23%
