Type of  CNC Milling Services

Aria offers 3-axis, 4-axis, and 5-axis CNC milling services to create complex geometric shapes with high accuracy. Our machining team can help customers control their CNC milling projects and ensure that the custom parts meet their strict requirements.

3 axis CNC milling services

3 axis CNC milling

This CNC milling process can be moved on the X, Y, and Z axes and can only do surface milling. It is suitable for manufacturing two-dimensional or simple three-dimensional parts, such as flat and simple curve parts, models, etc.

4 axis CNC milling Services
4 axis CNC milling

4 axis milling machines can rotate around A fixed axis, often referred to as the A-axis or axis of rotation, in addition to moving on the X, Y, and Z axes. This process can be used to process complex three-dimensional parts.

5 axis machining
5 axis CNC milling

This milling machine has the ability to move on the X, Y, and Z axes and rotate around two axes of rotation (A and B). The 5-axis CNC milling machine can handle more complex shapes, it is suitable for high precision parts manufacturing.

How does it work?

CNC Milling Service

CNC (Computer Numerical Control) milling is a process used to create complex and precise shapes by removing material from a workpiece using a cutting tool controlled by a computer program. Here’s how it works:


The first step in CNC milling is creating a 3D digital design of the part or component to be milled using computer-aided design (CAD) software. The design is then converted into a format that can be read by the CNC milling machine.


The converted design is loaded into the CNC milling machine's computer control system, which converts it into machine-readable code (G-code). This code contains instructions on how the cutting tool should move and remove material from the workpiece.


The workpiece is then secured onto the milling machine's worktable using clamps or other methods. The cutting tool is also installed and adjusted according to the required specifications.


Once everything is set up, the CNC milling machine is started, and the cutting tool moves according to the G-code instructions. The cutting tool removes material from the workpiece in a series of passes until the desired shape is achieved. During the milling process, the cutting tool may need to be changed or adjusted to achieve the desired result.


After the milling process is complete, the workpiece may require additional finishing steps, such as sanding or polishing, to achieve the desired surface finish.

CNC Machining FAQs

A: CNC machining is a wide-ranging manufacturing category involving multiple computer-managed processes. The objective is to remove enough raw material from a piece to achieve a state of near completion.

A: Aria is a professional CNC machining manufacturer in China, The reliability and precision of high-tech tools powered by sophisticated software programs give CNC machining the ability to quickly generate prototypes and complicated end-use parts having exceptionally tight tolerances. with low cnc machining costs from Chinese.

A: CNC machining is a subtractive manufacturing process. When the material is added instead of removed, it’s called an additive manufacturing process. Examples of subtractive CNC machining include specialized applications such as CNC milling services, turning, surface grinding, and EDM. An example of additive CNC machining is 3D printing.

A: The spinning motion from the CNC machine’s cutter will leave visible tool marks. Although they stand ready for immediate service, they can be further refined with anodizing, painting, polishing, and plating.
