The ball radius thing is similar to how a 0.5" square end mill isn't actually 0.5". In a lot of cases that applies to the ball unless you start with an oversized blank. Starting oversized so you can finish with a nominal size adds more work/cost so most manufacturers don't do it.

A novel, simple solvent-free synthetic procedure for N-Boc removal in ball mill in very mild reaction conditions at room temperature is described. This method has potential application in Boc group deprotection of other types of amines, in various fields such as synthesis of pharmaceutically interesting molecules, natural product synthesis, or ...
The ball screw is cleaned and completely inspected (See inspection procedure under Ball Screw Reconditioning). Bearing journals are inspected for proper size and critical runout and concentricity to the screw diameter. If the bearing diameters are worn, they need to be corrected for the ball screw to function properly in the machine tool.
Milling is the most common form of machining, a material removal process, which can create a variety of features on a part by cutting away the unwanted material. The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a piece of pre-shaped material that is secured to the fixture, which itself is attached ...

From the pellet chamber, feed may be directed by means of a butterfly valve to the cooler or on the floor for inspection. Another variable that may be introduced into the operation of a pellet mill is the rotational speed of the die. For the production of small diameter pellets (i.e., 3 mm or less) high rotation speeds are used.

Ball milling is a way to exfoliate graphite using lateral force, as opposed to the Scotch Tape or sonication that mainly use normal force. Ball mills, like the three roll machine, are a common occurrence in industry, for the production of fine particles. During the ball milling process, there are two factors that contribute to the exfoliation.
