A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis The balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size

Another difference is we typically are using flat nosed or bull nosed a flat end mill with a radius much less than the cutter radius end mills for 2 12D For 3D we typically use ball nosed end mills because they can cut a surface at any angle When it comes to feeds and speeds there are also many complications in 3D versus 2 12 D
