Basic Math For Ballnose Tools. The ballnose end mill is a special sort of tool. Its ability to mill up and down the contours of complex surfaces makes it invaluable to mold shops and other makers of 3D forms. And yet, the tool is lacking in a capability one might take for granted in other cutters: the ability to machine a flat surface. The ...

The Bond formula is better for primary ball mills, it typically gets the secondary ball mill ball size wrong, so the Azzaroni formula looks like it gives the right answer from an experience perspective. However, given the inactive kidney issue, efficiency is generally improved by adding in some larger balls to your makeup, such as 75 to 80 mm.
