About the influence of steel ball hardness, generally speaking, with the increase of hardness, as long as the steel ball isn’t broken, the unit consumption of steel ball will decline, at the same time the steel ball has the little deformation in the grinding process, with stronger force for grinding the ore grains, so as to improve the productivity of ball mill. However, the increase in

Finally, a ball profile features flutes with no flat bottom, and is rounded off at the end creating a “ball nose” at the tip of the tool. This is the strongest end mill style. A fully rounded cutting edge has no corner, removing the mostly likely failure point from the tool, contrary to a sharp edge on a square profile end mill. An end mill profile is often chosen by part requirements
