Name of eight kinds of commonly used milling cutter

A milling cutter is a rotary tool with one or more teeth for milling. When working, each cutter tooth cuts off the allowance of the workpiece intermittently in turn. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces and cutting workpieces on milling machines.

eight kinds of commonly used milling cutter:

1. Cylindrical milling cutter

For horizontal milling machine machining plane. The cutter teeth are distributed on the circumference of the milling cutter and are divided into straight teeth and spiral teeth according to the tooth profile. According to the number of teeth into two kinds of coarse teeth and fine teeth. The spiral tooth coarse tooth milling cutter has a small number of teeth, high tooth strength and large chip space, which is suitable for rough machining; the fine tooth milling cutter is suitable for finishing.

2. Face milling cutter

Also known as disc milling cutter, used for vertical milling machine, end face milling machine or gantry milling machine processing plane, end face and circumference have cutter teeth, also have coarse teeth and fine teeth. Its structure has integral type, insert type and indexable type 3.

3. End milling cutter

Used for processing grooves and step surfaces, etc., the cutter teeth are on the circumference and end surfaces, and cannot be fed along the axial direction during work. When the end mill has an end tooth through the center, it can be fed axially.

4. Three-sided milling cutter

It is used for processing various grooves and step surfaces, and has cutter teeth on both sides and circumference.

5. Angle milling cutter

Used for milling into a certain angle of the groove, there are two kinds of single angle and double angle milling cutter.

6. Saw blade milling cutter

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

7. T-shaped milling cutter

Used for milling T-slots.

8. Tine milling cutter

In the flank face of a narrow edge to form a back angle, due to the cutting angle is reasonable, its life is higher. The tooth back of the sharp tooth milling cutter has three forms: straight line, curve and broken line. Straight tooth back is often used for fine tooth finishing milling cutter. Curve and broken line tooth back of the cutter tooth strength is better, can withstand heavy cutting load, commonly used in coarse tooth milling cutter
