What is mill cutter?

Milling cutter refers to a rotary tool with one or more cutter teeth used in milling. When working, the cutter teeth successively intermittently cut off the workpiece's margin, which is mainly used in the milling machine processing plane, step, groove, forming surface and cut off the workpiece.

Introduction of milling cutter

The milling cutter is a multi-tooth rotary cutter, each of which is equivalent to a turning tool fixed on the rotary surface of the milling cutter. Milling at the same time to participate in the cutting edge is longer, and no empty stroke,Vc is also higher, so the productivity is higher. There are many kinds of milling cutter, different structure, a wide range of applications, according to its use can be divided into processing plane with milling cutter, processing groove with milling cutter, processing forming surface with milling cutter three categories.

Milling cutter refers to the use of rotating multi-edge cutting tool workpiece, is an efficient processing method. When working, the tool rotates (for the main movement), the workpiece moves (for the feed movement), the workpiece can also be fixed, but at this time the rotating tool must also move (complete the main movement and feed movement). Milling machine tools are horizontal milling machine or vertical milling machine, but also large gantry milling machine. These machine tools can be ordinary machine tools or CNC machine tools. Cutting using a rotary milling cutter as a tool. Milling is generally carried out on a milling machine or boring machine, suitable for machining planes, grooves, various forming surfaces (such as milling keys, gears and threads) and special shape of the die, etc.

Characteristics of milling cutter

1. the cutter teeth periodically participate in intermittent cutting.

2. The cutting thickness of each tool tooth is changed in the cutting process.

3. each tooth feed αf (mm/tooth), represents the relative displacement of the workpiece in each time the milling cutter turns a cutter tooth.
Type of milling cutter

1.cylindrical milling cutter
Used for machining flat surfaces on horizontal milling machines. 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 divided into coarse teeth and fine teeth two. Helical coarse teeth milling cutter fewer teeth, high tooth strength, large chip space, suitable for rough machining; Fine tooth milling cutter is suitable for finishing.

2. Face milling cutter
Used for processing plane on vertical milling machine, end milling machine or gantry milling machine, end face and circumference have cutter teeth, also have coarse teeth and fine teeth. Its structure has integral, insert type and indexable type 3.

3. End milling cutter
It is used for processing grooves and step surfaces, etc. The cutter teeth are on the circumference and end face, and can not be fed along the axial direction when working. When the end mill has an end tooth through the center, it can be fed axially.

4.Three edge milling cutter
It is used for machining various grooves and step surfaces, and has cutter teeth on both sides and circumference.

5.Angle milling cutter
A groove for milling to a certain Angle, there are two types of single Angle and double Angle milling cutter.

6. Saw blade milling cutter
It is used for machining deep groove and cutting workpiece, and there are more cutter teeth on its circumference. In order to reduce the friction during milling, there are 15 '~1° auxiliary deflection Angle on both sides of the cutter teeth. In addition, there are keyway milling cutter, dovetail milling cutter, T - shaped milling cutter and various form milling cutter.

7.T shape milling cutter
Used to mill T-slots.
