Pure aluminium in a ball mill forms spherical particles that get smaller until the competing process of particles rejoining forms a limiting fineness. With the right additives and pretreatment the aluminium tears into smaller particles with much more surface area than spheres, and keeps getting finer as milling progresses.

End mills for cutting aluminum are razor sharp and often have a radical helix angle. This combination makes it very easy to chip the corner of the cutting edge. If you can, use an end mill with a corner radius to reduce the risk of corner chipping. FEEDS AND SPEEDS: For production, you can push the tool to at least 1% of its diameter per tooth.
