1) Disc milling cutter; generally used in the disc cutter body machine clip blade or head composition, often used for end milling larger plane.

2) End milling cutter; End milling cutter is one of the most commonly used milling cutters in NC milling, which is widely used to process plane parts. Figure 4-3 is the two most common end milling cutters. In addition to end milling, end milling cutters are also commonly used for side edge milling. Sometimes end and side edges are simultaneously milling. End milling cutters can also be called cylindrical milling cutters.

3) Forming milling cutter

Forming milling cutters are generally designed and manufactured for specific workpieces or processing contents. They are suitable for processing specific shapes of planar parts (such as angular surface, groove surface, etc.) as well as special holes or tables. Figure 4-4 shows several commonly used forming milling cutters.

4) Ball end milling cutter. It is suitable for processing space curved surface parts, and sometimes for repairing large transition concave arcs of plane parts. Figure 4-5 is a common ball-end milling cutter.

5) Drum milling cutter. Fig. 4-6 is a typical drum milling cutter, which is mainly used for approximate processing of variable-angle surface of variable-angle parts.

In addition to the above types of milling cutters, CNC milling machine can also use a variety of general milling cutters. However, due to the special broach device in the spindle of many CNC milling machines, or because the taper of the spindle inner hole is different, the transition sleeve and pull rod must be prepared.
