Types and uses of milling cutters

1. By use

(1) Cylindrical milling cutter

For machining flat surfaces on horizontal milling machines. The cutter teeth are distributed on the circumference of the milling cutter, and are divided into two types: 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-toothed coarse-toothed milling cutter has fewer teeth, high tooth strength and large chip space, and is suitable for rough machining; fine-toothed 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 end face and circumference. There are cutter teeth, coarse teeth and fine teeth. Its structure has three types: integral type, insert type and indexable type.

(3) End mill

It is used to process grooves and stepped surfaces, etc. The cutter teeth are on the circumference and end faces, and cannot be fed in the axial direction during work. Axial infeed is possible when the end mill has end teeth through the center.

(4) Three side edge milling cutter

It is used to process various grooves and steps, and there are cutter teeth on both sides and circumference.

(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) saw blade milling cutter

It is used to process deep grooves and cut off workpieces, and there are more cutter teeth on its circumference. In order to reduce friction during milling, there are 15'-1° secondary deflection angles on both sides of the cutter tooth. In addition, there are keyway milling cutters, dovetail milling cutters, T-slot milling cutters and various form milling cutters.

2. According to the structure

(1) Integral type The cutter body and cutter teeth are made into one piece.

(2)Integral welding tooth type The cutter teeth are made of hard all
