Concept Behind Ball Milling

The ball mill system consists of one turn disc (turn table) and two or four bowls. The turn disc rotates in one direction while the bowls rotate in the opposite direction. The centrifugal forces, created by the rotation of the bowl around its own axis together with the rotation of the turn disc, are applied to the powder mixture and milling.

    Cutting Tools Cutting Tool Applications, Chapter 12 Milling Cutters and Operations. Milling is a process of generating machined surfaces by progressively removing a predetermined amount of material from the workpiece, which is advanced at a relatively slow feedrate to a milling cutter rotating at a comparatively high speed.A common milling operation to produce convex and concave parts. The process includes 3 steps – roughing, semi finishing and finishing. Roughing uses round inserts to do the initial work for removing most of the material. Ball nose end mills are the perfect fit for semi finishing and finishing.
