Experiment Part A: Ball Milling - Blogger
Ball milling is a type of grinder used to grind materials into fine powder. Ball mills rotate around a horizontal axis, partially filled with the coarse salt to be ground plus the grinding medium. There are many types of grinding media suitable for use in a ball mill, each material having its own specific properties and advantages.

0.2mm End Mills | McMaster-Carr
Make finishing cuts in tool steel and hardened steel with these cubic boron nitride (CBN) end mills. Harder than carbide end mills, they're better for making small, precise cuts and last more than five times as long. And while they're not as hard as diamond end mills, they dissipate heat much better. These end mills have a 0° helix angle for increased rigidity, helping to prevent …

Ball End Mills - Grainger Industrial Supply
Also known as ball-nose end mills, they are rotated against a workpiece to make round-bottomed slots and pockets or mill complex shapes without sharp corners. Each end mill has flutes on its cutting head that carry chips away from the workpiece to prevent damage to the end mill or workpiece. End mills are used on CNC or manual milling machines.
