These are two of the most prevalent milling operations, each using different types of cutters – the and mill and the face mill. The difference between end milling and face milling is that an end mill uses both the end and the sides of the cutter, whereas face milling is used for horizontal cutting.
These tools usually have a flat bottom but not always. Round and radiused cutters are also available. End mills are similar to drills in the sense that they can cut axially. But the advantage for milling lies with the possibility of lateral cutting.
Face mills cannot cut axially. Instead, the cutting edges are always located on the sides of the cutting head. The cutting teeth are replaceable carbide inserts.
This makes the lifetime of a tool longer while maintaining a good cutting quality.
Ball cutters, also known as ball mills, have hemispherical cutting tips. The objective is to maintain a corner radius for perpendicular faces.
