Nowadays, the technology of CNC milling machine is constantly developing and its functions are more perfect. Therefore, everyone has higher requirements for milling cutters on milling machines. There are many commonly used types of milling cutters according to their purposes.
Milling cutter is a kind of rotary cutter mainly used for machining planes, steps, grooves, forming surfaces and cutting off workpieces on milling machines. When working, each cutter tooth intermittently cuts off the margin of the workpiece. There are several common types of milling cutters, such as cylindrical milling cutters, face milling cutters, end mills, face milling cutters, angle milling cutters, saw blade milling cutters, and T-shaped milling cutters:
Cylindrical milling cutter: used for processing planes on horizontal milling machines. The cutter teeth are distributed on the circumference of the milling cutter. According to the tooth shape, they are divided into straight teeth and spiral teeth. According to the number of teeth, there are two types: coarse teeth and fine teeth. The helical coarse-tooth milling cutter has few teeth, high tooth strength and large chip space, suitable for rough machining; fine-tooth milling cutter is suitable for finishing.

Face milling cutter: It is used to process plane on vertical milling machine, face milling machine or gantry milling machine. There are cutter teeth on the end face and circumference, as well as coarse and fine teeth. Its structure has three types: integral type, insert type and indexable type.
End milling cutter: used for processing grooves and step surfaces, etc. The cutter teeth are on the circumference and end surface, and cannot be fed along the axial direction when working. When the end mill has end teeth passing through the center, it can feed axially.
Three-sided edge milling cutter: used for processing various grooves and stepped surfaces, with teeth on both sides and circumference.
Angle milling cutter: used for milling grooves at a certain angle, there are two kinds of single-angle and double-angle cutters.
Saw blade milling cutter: used to process deep grooves and cut off workpieces, with more teeth on the circumference. In order to reduce the friction during milling, there are 15’~1° secondary deflection angles 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.
T-shaped milling cutter: used to mill T-shaped slots.
