Theball millis a tumblingmillthat 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 minimizeballcoating, or slurry containing 20–40% water by weight.

If you are using an 8mm ball mill, then 6mm stepover is still very aggressive and will leave a very irregular surface for the finish pass. The goal is to get as uniform a surface as possible for the finish pass so the cutter bends by a uniform amount. Any change is the amount of force on the cutter will show up on the surface of the finish cut.
