The working principle of ball mill

22-05-2019The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force. At a certain height, it will automatically fall and impact and

How to use a tooling ball?

25-09-2017Tooling balls are really useful when you need to set work up on a sine plate. All of a sudden, all your references surfaces are gone, and the edges have turned into corners, which are inaccurate to pick up. If you had the foresight to install a tooling ball at a known location, you now have a point defined in all three axes to work from. Dennis

Down milling vs. up milling

In up milling (conventional milling), the feed direction of the cutting tool is opposite to its rotation. The chip thickness starts at zero and increases toward the end of the cut. The cutting edge has to be forced into the cut, creating a rubbing or burnishing effect due to friction, high temperatures and, often times, contact with a work-hardened surface caused by the preceding edge.
