Milling Machine Terminology – Sherline Products
End Mills—They look like drill bits but are sharpened on the sides as well as the ends. Held in an end mill holder, they are used to cut slots, pockets or surfaces. End mills are normally flat but "ball end" mills are also available that have a round end for leaving a radius in the corner of a pocket or a round-bottomed slot.

Ball Mills - an overview | ScienceDirect Topics
A ball mill is a type of grinder used to grind and blend bulk material into QDs /nanosize using different sized balls. The working principle is simple; impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell.

Pharmaceutical Technology: PRACTICAL I : BALL MILLING
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.
Optimization of mill performance by using
As indicated on the graph, a small variation in power could be the result of a significant variation of balls filling degree. As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor.
