Do you know the classification and related parameters of milling cutters in CNC machining? Next, Xiehe Processing Manufacturer will give you a brief introduction.

Classification introduction of milling cutters:

Sharp tooth milling cutter:

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

Shovel tooth milling cutter:

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

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

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

2. The feed per revolution f (mm/revolution) represents the relative displacement between the milling cutter and the workpiece during each revolution;

3. The feed per tooth af (mm/tooth) represents the relative displacement of the workpiece every time the milling cutter rotates through one tooth.

CNC machining milling cutter milling depth ap (mm) is the contact length between the milling cutter and the workpiece measured 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 high-speed steel milling cutters of CNC processing equipment for milling medium carbon steel is generally 20~30 m/min (n=7000/D~10000/D); the cutting speed of carbide milling cutters can reach 60~90 m/min (can Estimated based on 3 times the high speed steel milling cutter).
