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

Ball end mills are used for drilling shallow holes slotting a channel where a flat bottom is not required or most commonly used to produce multidimensional contours in molds or dies the design of ball end mills forms a hemispherical cutting action identical to the diameter of the tool because of the shapes required in these products its common that multi axis machining
