What Are The Classifications Of Milling Cutters

By milling cutter blade type

Flat end milling cutter: also known as end milling cutter, light cutter, Gong cutter and purple cutter, it is often used for finishing, semi finishing and finishing of plane, side plane, groove and mutually perpendicular step surface. The more the number of milling cutter edges, the better the effect after finishing.

Rough skin milling cutter: also known as wave edge cutter, it is used for rough machining of workpiece surface. According to the tooth shape size of wave edge, it is divided into coarse teeth, medium teeth and fine teeth. The tooth shape is different, and its processing parameters are also different. Generally, this kind of milling cutter allows a large cutting amount, so the roughening of workpiece is the first choice.

Ball end milling cutter: because the edge shape is spherical, it is called ball end milling cutter, also known as computer ball cutter or R milling cutter. It is often used for semi finishing and finishing of various curved surfaces and arc grooves.

Round nose milling cutter: also known as ox nose milling cutter or fillet milling cutter, it is mostly used to process right angle step surface or groove with R angle, and is mostly used for semi finishing and finishing.

Copper aluminum milling cutter: it is mainly made according to the characteristics of copper and aluminum materials. It is characterized by large front angle, large back angle (sharp cutter teeth), large spiral and good chip removal effect. It is the first choice for copper processing and aluminum processing.

T-groove milling cutter: mainly used for processing T-groove and side groove.

Chamfering milling cutter: mainly used for chamfering the inner hole and shape of the die. The chamfering angles are 60 degrees, 90 degrees and 120 degrees.

Inner r milling cutter: also known as concave arc end milling cutter or anti-R ball cutter, it is mainly used for milling convex R-shaped surface.

Countersunk end milling cutter: mainly used for machining hexagon socket screws, die thimbles, die nozzles and countersunk holes.

Slope cutter: also known as taper cutter, it is mostly used for conical surface processing after ordinary edge processing, die draft allowance processing and concave part processing. The inclination of the tool is the degree of one side.

Dovetail groove milling cutter: shaped like a swallow tail, it is mostly used for machining dovetail groove surface workpieces.

By purpose

(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 are divided into straight teeth and spiral teeth according to the tooth shape. According to the number of teeth, it is divided into coarse teeth and fine teeth. Spiral tooth coarse tooth milling cutter has few teeth, high tooth strength and large chip holding space, which is suitable for rough machining; Fine tooth milling cutter is suitable for finish machining.

(2) Face milling cutter

It is used in vertical milling machine, end milling machine or gantry milling machine to process plane. There are cutter teeth on the end face and circumference, as well as coarse teeth and fine teeth. Its structure has three types: integral type, inlaid type and indexable type.

(3) End milling cutter

It is used to process grooves and step surfaces. The cutter teeth are on the circumference and end face, and cannot be fed along the axial direction during operation. When the end milling cutter has end teeth passing through the center, it can be fed axially.

(4) Three edge milling cutter

It is used to process various grooves and step surfaces. There are cutter teeth on both sides and circumference.

(5) Angle milling cutter

It is used for milling grooves at a certain angle, including single angle milling cutter and double angle milling cutter.

(6) Saw blade milling cutter

It is used for machining deep grooves and cutting workpieces. There are many cutter teeth on its circumference. In order to reduce the friction during milling, there is a secondary deflection angle of 15 '- 1 ° on both sides of the cutter teeth. In addition, there are keyway milling cutter, dovetail groove milling cutter, T-groove milling cutter and various forming milling cutters.

By structure

(1) The integral cutter body and cutter teeth are made into one.

(2) The integral welded teeth are made of cemented carbide or other wear-resistant tool materials and brazed on the tool body.

(3) The inlaid cutter teeth are fastened on the cutter body by mechanical clamping. The replaceable cutter teeth can be a cutter head of integral tool material or a cutter head of welding tool material. The milling cutter with the cutter head mounted on the cutter body for grinding is called internal grinding type; The tool head is grinded separately on the fixture, which is called external grinding type.

(4) The indexable structure has been widely used in face milling cutter, end milling cutter and three face edge milling cutter.
