The feed direction is important because it affects the performance of the mill and the quality of the workpieces. Cutting speeds have to match accordingly with the type of material and cutter. Moreover, cutting speeds should also match the type of work done by the mill such as finishing. Amended list of feeding rates is also provided by various manufacturers for the proper operation of
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.
Keep a low cut width or cut depth if youre talking the floor of a pocket or surfacing with a Face Mill and do a separate finish pass. The depth of cut has to be larger than the chip load, or you can get rubbing. Usually something like 2 3x chip load will be right for the finish pass. I do a lot of finish passes in the 0.015 neighborhood. The lighter pass will reduce cutting force and
