### Ball End Mills For Milling Aluminum-Carbide-High Performance

Ball end mills or "ball nose end mills" for cutting aluminum are single end, high performance mills used for making full radiused grooves, generating large corner radii, or contour profile milling. CNC milling of aluminum can be difficult, because the material can stick to the flutes and the chips can pack.

### Factors Affecting Ball Mill Grinding Efficiency

b) Feed Preparation – With more widespread use of coarse ball milling it is increasingly important to present a suitable feed material top-size to the ball mill. Significant inefficiencies are introduced as a result of the need for larger (and, as a result, fewer) grinding balls. Furthermore, as mill performance is related to the complete size distribution of the feed material, all ...
