Ball Mill Grinding Media – Grinding Media Balls & Cylpebs …
There are three ways for grinding media to pulverize materials: 1. Rolling: the grinding media rolls in the grinding chamber and pulverizes the material by self-weight. 2. Impact: with the rotation of the ball mill cylinder, grinding media falls from the high place in the grinding chamber and strikes the material. 3.

0.02" End Mills | McMaster-Carr
For longer tool life and a better finish in general purpose milling applications, these solid carbide end mills are harder, stronger, and more wear resistant than high-speed steel and cobalt steel end mills. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. …
