A ball mill is a type of grinder used to grind or 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 mill consists of a hollow cylindrical shell rotating about its axis. The axis of the ...

 · End mills can have a wide variety of cutting edges (or flutes), ranging from just 1 (in micro end mills) to as high as 16. Feed direction for drilling is always axial to the cutter. Feed direction in end milling with flatend mill is usually perpendicular to the cutter. With ball end mill, feed can be given at any angle to the cutter axis.
