A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
A ball nose end mill, also known as a spherical end mill or ball end mill, has a semi sphere at the tool end. There are two variant in Ball nose end one of them is Standard Ball Nose End Mill and another is Long Ball Nose End Mill.
Cutting tools used on these machines may be as large as a 3/4-inch diameter end mill (a shop-imposed limit) or as small as a 0.0013 inch end mill (barely visible without magnification). The microscope is needed to align workpieces, set tool lengths and monitor cutting with extremely small tools.
