Tool Points: Milling utilizes a multipoint tool, meaning the cutter has multiple cutting edges. These edges work collaboratively to shape the material. It's teamwork at its finest! On the other hand, grinding employs a singlepoint cutting tool. Here, it's one abrasive grain at a time doing the job, painstakingly refining the surface.

Media Milling, Dry and Wet. Ball milling, or media milling, uses collision and shear forces to grind down material, whether wet or dry. A ball mill can operate at either high or lowenergy outputs, and material characteristics can span a wide range. Adjustable variables include ball types and sizes, speeds, material mass in slurry, and more.
