① Cylindrical milling cutter: used for machining planes on horizontal milling machines. The cutter teeth are distributed on the circumference of the milling cutter, and are divided into straight teeth and helical teeth according to the tooth shape. According to the number of teeth, there are two kinds of coarse teeth and fine teeth. The helical-tooth coarse-tooth milling cutter has few teeth, high tooth strength, and large chip space, which is suitable for rough machining; fine-toothed milling cutter is suitable for finishing.
② Face milling cutter: It is used for machining planes on vertical milling machines, face milling machines or gantry milling machines. There are cutter teeth on the end face and circumference, as well as coarse teeth and fine teeth. Its structure has three types: integral type, insert type and indexable type.
③ End mill: It is used for machining grooves and stepped surfaces. The cutter teeth are on the circumference and end face, and cannot be fed in the axial direction during operation. When the end mill has end teeth passing through the center, it can be fed axially.
④ Three-side edge milling cutter: It is used to process various grooves and stepped surfaces, and there are cutter teeth on both sides and the circumference.
⑤ Viewpoint milling cutter: It is used to mill a groove with a certain viewpoint. There are two kinds of single-angle and double-angle milling cutters.
⑥ Saw blade milling cutter: It is used for machining deep grooves and cutting workpieces, and there are many teeth on its circumference. In order to reduce the conflict during milling, there is a secondary declination angle of 15′～1° on both sides of the cutter teeth. In addition, there are keyway milling cutters, dovetail milling cutters, T-slot milling cutters and various forming milling cutters.
