Introduction to Milling Tools and Their Application

Ball end mills are used for contour milling, shallow slotting, contour milling and pocketing applications. Spiralshaped cutting edges are cut into the side of the end mill to provide a path for chips to escape when an end mill is down in a slot or a pocket. The most common options are 2, 3, or 4 flutes.

Mechanical Milling: a Top Down Approach for the Synthesis ...

a brief description regarding high energy ball mills. Figure 1. A rock tumbler Ball mills . The tumbler ball mill is a cylindrical container rotated about its axis in which balls impact upon the powder charge. The balls may roll down the surface of the chamber in a series of parallel layers or they may fall freely and impact the powder and balls beneath them. The tumbler ball mill is illustrated in Fig. 1.
