Do you know the classification and related parameters of milling cutters in CNC machining? Next, the precision parts processing manufacturer will give you a brief introduction.

Introduction to the classification of milling cutters:

Sharp tooth milling cutter:

A narrow margin is ground on the flank to form a relief angle. Due to the reasonable cutting angle, its service life is relatively high. The tooth back of the sharp-tooth milling cutter has three forms: straight line, curved line and broken line. Straight backs are often used for fine-toothed finishing milling cutters. The teeth with curved and broken line tooth backs have better strength and can withstand heavy cutting loads, and are often used in coarse-toothed milling cutters.

Shovel tooth milling cutter:

The back of it is processed into the tooth back of the Archimedes spiral by shoveling (or shovel grinding). After the milling cutter is blunt, it only needs to regrind the front to keep the original tooth shape unchanged. It is used to manufacture gear milling cutters, etc. Various form milling cutters.

The cutting speed v (m/min) of cnc machining milling cutter is the peripheral speed of the milling cutter edge. Anyone who does cnc processing knows that setting the cutting parameters of the milling cutter is an important part of processing qualified workpieces. There are three ways to express the milling feed:

1. The feed rate per minute vf (mm/min), which means the displacement of the workpiece relative to the milling cutter per minute;

2. Feed per revolution f (mm/revolution), which means the relative displacement between the milling cutter and the workpiece when one revolution per revolution;

3. The feed per tooth af (mm/tooth) indicates the relative displacement of the workpiece within the time when the milling cutter rotates one tooth.

The milling depth ap (mm) of cnc machining milling cutter is the contact length between the milling cutter and the workpiece measured in the direction parallel to the axis of the milling cutter. The milling cutting arc depth ae (mm) is the depth of the contact arc between the milling cutter and the workpiece measured perpendicular to the axis of the milling cutter.

The cutting speed of carbon steel in high-speed steel milling cutter milling of cnc processing equipment is generally 20-30 m/min (n=7000/D~10000/D); the carbide milling cutter can reach 60-90 m/min (can be Estimated by 3 times high-speed steel milling cutter).
