A long bv-shaped end is great for wood carving and a shallow v-shaped end mill is great for lettering. There is also the square end end mills that create a nice flush bottom of a center cut. The applications are endless. One final type of end mill that is worth mentioning is the roughing mill also called the hog mill.

Use to mill cast iron, stainless steel, nickel-based alloys, and titanium. Not for use on aluminum. Color is purple-gray. The choice to use coated end mills is a cost versus benefit choice. If your machining benefits enough from the extra performance of a premium coating, purchase end mills with a coating. Face Mills and Indexable End Mills

Spiral-shaped 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. The more flutes, the more cutting edges but the narrower the channel for chip evacuation.

The types of mill normally encountered can further be classified according to the method of feeding the raw material to, and the removal of the final product from the mill. These classes are: Batch mills. Grate discharge mills. Trunnion overflow mills. Air-swept mills. The principles of these mills are illustrated in Fig. 1.4 and Fig. 1.5.

Grinding machine has been widely used in gold mines in South Africa since 1905. At that time, the grinding machine used river pebble as the grinding medium, which was essentially a gravel mill. Later, in order to improve the production capacity of the mill, cast iron balls were used as the medium, so normal gravel mills were evolved into ball mills and rod mills.
