Many types and geometries of ball mills exist and can be classified based on several criteria. At the lab scale, generally, they can be classified based on how the balls are moved inside of the jar. The type of mill decides the kinetic energy transferred to the powders and therefore the specific purpose of the technique.

Commercial mills for MA are much larger in size than the mills described above and can process several hundred pounds at a time. Mechanical alloying for commercial production is carried out in ball mills of up to 3000 lb capacity (Fig. 5). The milling time decreases with an increase in the energy of the mill.

Downcut bits are the reverse of the upcut bit. The material you're removing is "pushed" downward away from the router or spindle. The rough edge, then, will be at the bottom of your material. The top edge of your material will be very clean when using a downcut bit. Downcut bits are good for finish passes.
