CNC machining center to talk about the type of milling cutter

First of all, we have to know what milling cutter is? A rotating tool with one or more teeth for milling. When working, the cutter teeth cut off the allowance of the workpiece intermittently in turn. Milling cutter is mainly used for machining plane, step, groove, forming surface and cutting workpiece on milling machine. There are many types of milling cutters according to their uses.

① Cylindrical milling cutter: used for machining plane on horizontal milling machine. The cutter teeth are distributed on the circumference of the milling cutter and can be divided into straight teeth and spiral teeth according to the tooth shape. According to the number of teeth, it can be divided into coarse teeth and fine teeth. The helical coarse tooth milling cutter is suitable for rough machining because of its small number of teeth, high tooth strength and large chip space; Fine tooth milling cutter is suitable for finishing.

② Face Milling Cutter: it is used for vertical milling machine, end milling machine or gantry milling machine to process plane. There are cutter teeth on end face and circumference, as well as coarse teeth and fine teeth. There are three types of structure: integral type, inlaid type and indexable type.

③ End milling cutter: it is used for machining groove and step surface. The cutter teeth are on the circumference and end face, and can't feed along the axial direction when working. When the end milling cutter has an end tooth passing through the center, it can feed axially.

④ Three side milling cutter: it is used to process all kinds of grooves and step surfaces. There are cutter teeth on both sides and circumference.

⑤ Angle milling cutter: used for milling groove with certain angle, including single angle milling cutter and double angle milling cutter.

⑥ Saw blade milling cutter: it is used to process deep groove and cut off workpiece. There are many cutter teeth on its circumference. In order to reduce the friction during milling, there are 15 "to 1" on both sides of the cutter teeth ° The secondary deflection angle of the system.

In addition, there are keyway milling cutter, dovetail milling cutter, T-groove milling cutter and various forming milling cutters.

There are four kinds of milling cutter structure

① Integral type: the cutter body and cutter teeth are integrated.

② Integral welding tooth type: the cutter teeth are made of cemented carbide or other wear-resistant tool materials and brazed on the cutter body.

③ Inlaid type: the cutter teeth are fixed on the cutter body by mechanical clamping. The replaceable cutter teeth can be the cutter head of the whole cutter material or the cutter head of the welding cutter material. The milling cutter with the cutter head mounted on the cutter body for grinding is called internal grinding type; If the cutter head is grinded separately on the fixture, it is called external grinding.

④ Indexable: this structure has been widely used in face milling cutter, end milling cutter and three face milling cutter.

CNC machining center said that only after understanding the type and function of milling cutter, according to the processing needs, reasonable selection of suitable milling cutter can greatly save processing time, improve processing quality and improve production efficiency.
