What is CNC Milling?

CNC milling is one of the most important machining methods in precision CNC machining. Milling is that to fix the work piece, and use a high-speed rotating milling cutter to move on the material to cut out the required shapes and features. As a reliable CNC milling parts manufacturer in China, we take full advantages of 3d, 4, and 5 axis CNC milling machines, with cheap CNC milling service price. Choose the best CNC milling solution for your milled parts.


The Difference Between CNC Turning and Milling?

Difference between CNC turning and milling: for parts with symmetrical or cylindrical features, CNC turning process is often preferred; for parts with square or rectangular features, CNC milling tends to be adopted. Usually, turning rotates the work piece against a cutting tool, while milling spins the cutting tool against a stationary work piece.



Advantages of Our CNC Milling Service

At present, we, a reliable customized CNC milling company, have used more than 300 kinds of metals and engineering-grade plastics in CNC milling. You’ll get the advantages when choose us:

Custom machined rapid prototype part as fast as in 1 day. 

More competitive price and reduced cost for high volume CNC milling production.

Advanced programming and technology in 4,5 axis indexing milling.

First article report (F.A.I), material certification (SGS) and surface treatment test.

With minimal human intervention, CNC milling avoids human error to a large extent.

Able to produce CNC milling small parts with incredibly precise and same measurements.   

Capable of handling large-scale production in a short period.

Keep uniformity and same components can be produced again and again.



CNC Milling FAQs

CNC Milling Methods

CNC milling is actually a subtraction process, that is removing the material from the work piece to get the ideal shape. Some common CNC milling methods are used during the process:   


Plain milling: the cutting tool works along the surface of the work piece, with the rotating axis parallel to the material. 

Face milling: the cutting tool faces down against the surface, with the axis perpendicular to the work piece.

Angular milling: the axis and the surface are at an angle during the removing, producing angular cuts which are designed in advance. 

Form milling: this method allows for the processing of non-flat cuts like curves and contours 


CNC Milling Operations

CNC milling operations mainly involve a cutting tool and a work piece. Move the cutting tool on the surface of the material such as aluminum while adopting different milling methods, whittle away the unnecessary until you get the desired shape. 

3-Axis to 5-Axis: CNC Milling Machine Capabilities Compared

The process of 3-axis CNC milling is relatively simple. It works on a part from 3 dimensions, namely the height, width and depth. With another two rotary axes A and B, 5-axis CNC milling allows a component being handled from 5 angles. Compared with the effective 3-axis CNC machining, milling machines capable of 5 dimensions bring greater intricacy and precision.

How to Choose CNC Milling Services
