A cutter is a very important tool in CNC lathe machining. With the development of CNC machines, there are more and more types of cutters. According to different processing methods and different products, the choice of the cutter is not the same. Well, among the CNC cutting tools, the CNC milling cutter is the most commonly used.

Classification Of CNC Milling Cutter 

In this paper, we mainly talk about the classification according to functions in the CNC milling service.

Cylindrical Milling Cutter

It is used for horizontal CNC milling machining plane and cutter tooth distribution on the circumference of the cutter. Tooth shape is divided into straight teeth and spiral teeth two kinds. The number of teeth is divided into two kinds of thin teeth and dense teeth. Spiral tooth and thin tooth milling cutter teeth less, high tooth strength, large chip space, suitable for rough machining; And the dense tooth milling cutter is suitable for finishing.

Face Milling Cutter

It is used for vertical milling machines, horizontal milling machines, or planer milling machines. There are cutter teeth on the end face and circumference. Face milling cutter also has coarse teeth and fine teeth points, its structure is integral, insert teeth and indexable type three.

Vertical Milling Cutter

It is used for processing groove and step surface, cutter teeth on the circumference and end face, generally can not work along with the axial feed. When the end mill has through the center teeth, can be axial feed.

Side Milling Cutter

It is used for processing all kinds of grooves and step surfaces, and its two sides and circumference are equipped with cutter teeth.

Angle Milling Cutter

It is used for milling into a certain Angle groove, there are single Angle milling cutters and double Angle milling cutters two kinds.

Saw Blade Milling Cutter

It is used for processing deep grooves and cutting workpieces, its circumference has more cutter teeth. To reduce the friction during milling, there are 15 '~1° auxiliary deviation angles on both sides of the cutter teeth.

Die Milling Cutter

Die milling cutters are used to process die cavities or punch forming surfaces. Die milling cutter is evolved from end milling cutter, according to the shape of the working part can be divided into conical flat head, cylindrical ball head, and conical ball head three. Carbide dies milling cutter is very widely used, in addition to milling all kinds of the die cavity, but also can replace the hand file and grinding wheel grinding head cleaning casting, forging, welding parts of the flying edge, as well as some forming surface finishing processing. The milling cutter can be installed on wind or electric tools, productivity and life than grinding wheel and file tens of times.

Gear Milling Cutter

According to the profile method or without instantaneous core envelope method of cutting tools,  according to the shape of the different divided into disk gear milling cutter and finger gear milling cutter.

Thread Milling Cutter

It is a tool for milling threads through three or more axis machining centers.

In addition, there are keyway milling cutters, dovetail groove milling cutters, T-groove milling cutters, and various shaped milling cutter

In The End

There are many other types of cutters for CNC milling machining. If you are interested, we will continue to introduce it in the following papers.
