Multiple teeth come into contact with the workpiece at the same time.
The cut bits of metal are smaller than usual and therefore easier to clear. These make the cutting process faster than with a regular end mill. Roughing end millĪs the name says, these are pretty much end mills with a slight difference. Here, the workpiece is fed into the inner part of the mill to produce a cylindrical outcome. Hollow mills are basically the opposite of face mills. Fly cutters are just cheaper and the cutting bits are often made at the shop by a machinist rather than bought from stores. They consist of a central body that holds either one or two tool bits (double-end fly cutters).įace mills are better for high quality cutting. These tools have the same function as face mills. There are different cutters available to produce gears within a certain number of teeth. There is a special cutting tool for milling involute gears. This makes the functionality very similar to end mills but their popularity has waned over the years with the advancement of other technologies. Side-and-face cutters have teeth around the circumference as well as on one side. Side-and-face cutterĪ predecessor for the end mill. The slab itself spins in a horizontal position between the spindle and the support. That is also why slab milling is often called surface milling.

Rather, they are still used with manual milling machines to quickly machine large surfaces. Slab mills are not that common with modern CNC machining centres. The objective is to maintain a corner radius for perpendicular faces. Ball cutterīall cutters, also known as ball mills, have hemispherical cutting tips. This makes the lifetime of a tool longer while maintaining a good cutting quality. The cutting teeth are replaceable carbide inserts. Instead, the cutting edges are always located on the sides of the cutting head. But the advantage for milling lies with the possibility of lateral cutting. End mills are similar to drills in the sense that they can cut axially. Round and radiused cutters are also available. These tools usually have a flat bottom but not always. 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 are two of the most prevalent milling operations, each using different types of cutters – the and mill and the face mill. What is the difference between end milling and face milling? The most common types of milling cutters are:įirst, we should start with one of the primary questions. III Selecting the Right Machine Tool What Are the Types of Milling Cutters?
