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.

For the micro WC ball end mill, the main processing method is grinding. The processing efficiency would be very low for superhard material, particularly PCD which is 80120 times harder than WC, if using the method of grinding. So the processing method for micro PCD ball end mill combined the advantages of two present processing methods.
