End Mill Feeds and Speeds. The most important aspect of milling with end mills is to run the tool at the proper RPM (revolutions per minute or spindle speed) and IPM (inches per minute or feed rate). We have broken these recommendations down into material categories so you can make better decisions with how to productively run your end mills.

The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse feed materials and the smaller balls help to form fine product by reducing void spaces between the balls. Ball mills grind material by impact and attrition.
