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: used for vertical milling machine, face milling machine or gantry milling machine, upper processing plane, there are cutter teeth on the end face and circumference, and there are coarse teeth and fine teeth. Its structure has three types: integral type, insert type and indexable type.
③ End mill: used for machining grooves and stepped surfaces, etc. The cutter teeth are on the circumference and end face, and cannot be fed in the axial direction during operation. Axial feed is possible when the end mill has end teeth that pass through the center.
④ Three-sided edge milling cutter: used for machining various grooves and stepped surfaces, and there are cutter teeth on both sides and circumferences.
⑤ Angle milling cutter: used for milling grooves with a certain angle, there are two kinds of single-angle and double-angle milling cutters.
⑥ For machining deep grooves and cutting workpieces, there are more teeth on the circumference. In order to reduce friction during milling, there are 15' to 1° secondary declination 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.
