Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
Anti Backlash for CNC: Ball Screws, Bearing Blocks, and Anti Backlash Nuts. Anti Backlash Ball Screwws… If you're looking over this page, I'll assume you wonder why you should eliminate backlash (or how much can your stand), you want to build a CNC machine from scratch, or you are converting a manual machine that has measurable backlash.

A ball nut with all the backlash removed is called preloaded. There are several ways to reduce or eliminate the backlash in a ball screw assembly: At the factory level we can select ball sizes to minimize the backlash. This works well for small lead to diameter ratios, like a 5x25mm. In some cases we can preload a ball nut in this way.
Backlash can be tested with indicators, lasers, ballbars or other measuring devices to determine how much motion is lost when an axis reverses direction. This value is entered in the machines parameters, so when an axis changes direction, it compensates the amount in the parameter to determine when the axis will physically move.

A ball bar test revealed massive deviation from the acceptable limits. I would bet this is the exact same thing going on. You shouldn't need to replace much, but you will need to get the system dialed in and properly compensated. Getting a ballbar test is the best solution if it is in fact a backlash problem like you suggest.
A quick check of backlash in the machines around here: knee mill y = 0.025" knee mill x = 0.060" horizontal mill table = 0.035" horizontal mill saddle = 0.095" (that's 95% of a full turn! ) lathe cross = 0.015" lathe compound = 0.005" Knee mill is a 1984 Sharp/Alliant Horizontal is a 1953 B&S #2 Lathe is a 1983 Clochester 13" 8000

Because of the lack of backlash, you can "climb mill" with the ball screws, whereas you have to "conventional mill" with the lead screw. Less chatter when ...
The mechanical part consists of replacing the lead screws in the mini-mill with ball screws and double nuts. The reason why you need a new mechanical system is that the lead screws in benchtop mills have backlash and are not really built for CNC operation. Ball screws have very little backlash and are an excellent choice for the drive of a CNC.

The cost of edge drive is low, but the pinion needs to be replaced every 2-5 years. Edge drive is mainly used in coal mills and mills with small power. The girth gear(big ring gear) and pinion are the key of the edge transmission device. Their reliable operation is directly related to the stable production of the mill.
1475. My 1987 Taiwanese Webb mill was originally a CNC conversion at the point of sale, so it came to me with ball screws. The Y Axis has zero backlash and the X Axis has .007 which is no problem for manual use with a DRO. I agree with those who mentioned checking thrust bearrings since movement of the ball screw on its axis will transfer into ...
