Milling is a machining method in which a milling cutter is used as a tool to process the surface of an object. As the most commonly used machining process in machining centers, how much do you know about it?

Milling centre is generally suitable for machining planes, grooves, and various forming surface workpieces. It has the ability to efficiently process complex and different surfaces, and is the embodiment of the good operating performance of the machining center.

Features of milling centre:

Milling is a cutting method in which the rotary motion of the milling cutter is the main movement, and the milling cutter or the workpiece is used for the feed movement. Its unique features are:

• It is processed by multi-blade tools, and the blades are alternately cut. The tool has good cooling effect and high durability;

• Milling has high production efficiency and wide processing range. Various milling cutters can be used on ordinary milling machines to complete the processing of planes (parallel planes, vertical planes, inclined planes), steps, grooves (right-angle grooves, V-shaped grooves, processing tasks such as T-shaped grooves, dovetail grooves and other special-shaped grooves) and special-shaped surfaces. Coupled with the use of milling machine accessories such as indexing head, it can also complete the milling of workpieces such as spline shafts, helical shafts, and tooth clutches.

• Milling has high machining accuracy, its economic machining accuracy is generally IT9-IT7, and the surface roughness Ra value is generally 12.5-1.6um. The precision of fine milling can reach IT5, and the surface roughness Ra value can reach 0.20um.

Because of the above characteristics of milling, it is especially suitable for the processing of composite parts with complex shapes such as molds, and occupies a very important position in mold manufacturing and other industries.

With the rapid development of numerical control technology, the role of milling in machining is becoming more and more important, especially in the processing of various special-shaped surfaces, which has incomparable advantages over other processing methods.

At present, on the five-coordinate CNC milling machining center, it is even possible to continuously complete the reproduction of the entire artwork with high efficiency.

What is a milling machine center?

Milling machines mainly refer to machine tools that use milling cutters to process various surfaces of workpieces. Usually, the milling cutter mainly moves by rotation, and the movement of the workpiece and the milling cutter is the feed movement. It can process planes, grooves, and various curved surfaces, gears, etc.

Milling machines can make molds. Some parts we often see in our daily life have various shapes. These shapes are obtained by using molds to process materials.

Milling machines are also divided into vertical milling machines and horizontal milling machines. What is the difference between the two?

Vertical Milling Machine V.S. Horizontal Milling Machine

?Different axis positions

The horizontal spindle is arranged horizontally, and the vertical spindle is arranged vertically.

?Whether with vertical milling head (mainly used to distinguish)

Horizontal milling machines generally have an end milling head. Although this end milling head is not as powerful and rigid as a vertical milling machine, it makes the overall function of the horizontal milling machine more powerful than that of the vertical milling machine.

Vertical milling machines do not have this feature and cannot process workpieces suitable for horizontal milling. The productivity is higher than that of horizontal milling machines, and the stiffness is relatively better.

?Different scope of application

Vertical CNC milling machine is one of the most numerous CNC milling machines and has the widest range of applications. Horizontal milling expands the scope of use, and the machining accuracy is generally higher than that of vertical milling.

The milling cutters for vertical milling machines are relatively flexible and have a wide range of applications, but they are sufficient for vertical milling. It can be used for keyway milling, plane milling, boring, etc. Horizontal milling machines can also use the above various tools, horizontal multi-purpose disc milling cutters, auxiliary supports, drill bits, etc. are available.
