The long tool discussed later has an extended section of 5 mm. Typically a ball mill is used to fabricate free form surfaces and as a result the tool can be loaded axially, radially.

In a single op, you can have the ball engaged near the tip where the SFM is much lower, and other times engaged near the side where it behaves more like a straight endmill - and anywhere in between.
Live ChatThe operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, discharge of ground material performed.
