Our CNC Milling Capabilities


This video shows how we mill a precision and complex part from our 5-Axis CNC milling machines with different tools and how we guarantee the quality by using an on-machine inspection system.

Our experienced CNC machining engineers can select the right tools and optimize tool paths, achieve an ideal CNC milling surface, and keep tight tolerances. We can provide all types of custom CNC machined parts to meet your project needs.

If you are having problems getting your CNC milling parts done, contact us and try to get a solution from 3E.



Why Choose Us for Custom CNC Milling?

The Top 3 Reasons:

Cost Efficient
Cost Efficient

80% of aspect and mechanical parts can be CNC milled within minutes or even seconds by optimizing the tool paths and using special cutting tools. Our automation setup for CNC milling is super cost-efficient for mass production. It helps reduce CNC machining costs compared with additive manufacturing in most cases.

Materials & Finishes Options
Materials & Finishes Options

Besides our fast turnaround time, we have various types and specs of plastic and metal blocks available for CNC machining processes. We can also provide different surface finishing for CNC machined parts, such as painting, anodizing and chroming. It's an excellent combination of function and aspect.

2
Unlock Complexity
Unlock Complexity

Because the cutting tools of a milling machine can approach the workpieces from several different angles, it is possible to create CNC machined parts with complex shapes. With more axes, we can create milled parts with greater complexity. Milling is often the best bet if a project demands an irregular shape.

See why our customers love our CNC milling service



We received the CNC parts that you made for us, and I finally had a chance to open up the box and have a look at them today. They look very good! I am very impressed with the quality of your parts. The small details look very accurate, and the clear silver anodizing on the aluminum parts looks very clean and bright. Very nice work. Thank you!

We will definitely use 3ERP's CNC milling services again in near future.

CNC Milling FAQs

What is CNC milling?

CNC milling is just one of the CNC machining processes available. Milling is a particular form of precision CNC machining. Milling uses a cutter that removes material by moving into the workpiece at an angle. The movement of the cutter is controlled by computer instructions, allowing for extreme precision and repeatability.

Why use CNC milling?

Besides CNC turning, CNC milling is one of the most popular custom CNC machining processes. CNC milling services are used for the majority of machined parts because it can handle a wide variety of irregular geometries. It is also an efficient means of mass production once the setup is complete.

What kind of CNC machining equipment do you use?

3ERP’s facilities contain high-end 3-axis, 4-axis, and 5-axis CNC machining centers, including models from Haas and JingDiao.

Can I combine milling with other CNC machining processes?

Yes. We can use a CNC machine to mill details, features, and text onto parts made using other processes like casting and 3D printing.
