My mill is quite a bit slow for its size about 65 RPM, it should run near 100 RPM. Ball mills are typically run at about 7590% of the critical speed. The critical speed is the speed at which the media simply centrifuges right around against the walls. Smaller mills need to run faster, the critical speed is about 42/sqrt(diameter in metres).

The ball mill contains materials meant for crushing and grinding, such as balls of ceramic, small rocks, or balls made from stainless steel. The internal device of the ball mill grinds material into powderlike substances, and can rotate continuously for optimal grinding and refinery production.
Ball nosed cutters: slow nose speed. The biggest challenge with ball nosed end mills of various kinds is slow nose speed. As you get closer to the tip, the diameter on the ball gets smaller and smaller, finally going to zero. As a result, the cutter must perform over a wide range of surface speeds and chip loads at different depths in the cut.
A ball mill is an example of a comminution method which produces size reduction by both impact and attrition of particles. Ball mills consist of a hollow cylinder mounted such that it can be rotated on its horizontal longitudinal axis. Cylinder diameters can be greater than 3 m, although much smaller sizes are used pharmaceutically.
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

Ball mill. You could just send a ball mill right into your block, or you could remove some material with an windmill first and then plunge in, or you could remove some material and then actually ball mill it out. It takes a long time to do, and I''m sure there are added steps in programming to learn, BUT your ball mills will last MUCH longer.
