Custom CNC Milling Service
Start customizing your CNC milling parts and learn how we can provide quality CNC milling services.
Our CNC Milling Service
Our CNC milling service delivers custom prototypes and production parts with exceptional speed, capable of producing outcomes in as little as one day. Leveraging sophisticated 3-axis, 4-axis and 5-axis indexed milling processes, we handle an extensive range of over 30 engineering-grade plastics and metals.
This service is particularly suited for low-volume production of functional prototypes, dedicated jigs and fixtures, and production components.
For larger volumes, customers benefit from competitive pricing, comprehensive first-article inspection reports, material certifications, and finishing options such as anodizing and chromate plating.
CNC Milling Design Guidelines
When designing parts for CNC milling, adhering to specific guidelines ensures functionality and manufacturability. This introduction to CNC Milling Design Guidelines provides essential tips on material selection, geometric constraints, tolerances, and surface finishes. The guidelines are crafted to help designers and engineers optimize their designs for the milling process, thereby improving the overall quality of the final products and reducing manufacturing costs and time.

Our CNC service can create threads in standard sizes, supporting UNC and UNF threads from #2 up to half an inch and metric threads from M2 to M12.
However, leaving internal threads out of your initial part design is recommended. Adding threads during the design phase can complicate manufacturing, and it’s often more accurate to create them separately after the central part is milled.
In our Ultra Precision machining, we maintain strict tolerances, achieving accuracy within +/- 0.13 mm. For the best structural integrity and manufacturability, it’s advised that any part features should not be thinner than 0.51 mm. Furthermore, we recommend that the general thickness of parts should be no less than 1.00mm to ensure quality and durability.

Available Finishes
If you don't have the desired finish, please contact us, and we will customize the finish for you separately.
As-Milled
This is the fastest option where parts have visible tool marks and potentially sharp edges and burrs. These can be removed upon request.
Bead Blast
The part surface is media blasted, usually with glass beads, to create a smooth, matte appearance.
Anodized
Type II: Offers corrosion resistance.
Type III: Provides a thicker, wear-resistant layer in addition to the corrosion resistance of Type II.
Powder Coat
Powdered paint is sprayed onto a part and baked in an oven.
Why Use CNC Milling?
CNC milling is celebrated for its exceptional precision, allowing for the production of highly accurate parts essential in sectors like aerospace and medical technology. Its robust endurance enables around-the-clock operation, significantly enhancing productivity and scalability for both small and large-scale productions.
Additionally, CNC milling machines boast rapid processing speeds and advanced capabilities, efficiently handling complex designs and intricate parts that traditional machining cannot achieve. These advantages make CNC milling a pivotal technology in modern manufacturing, driving innovation and operational efficiency across various industries.
How Does CNC Milling Work?
CNC milling is a precision manufacturing process where a computer-controlled machine carves material from a solid workpiece to create complex parts. It begins by securing the workpiece and installing the appropriate tools. The machine is programmed with G-code, derived from CAD designs, dictating the path, depth, and speed of the cuts.
Milling can be performed in various directions using either climb (down) or conventional (up) milling techniques, depending on the desired precision and finish. Modern CNC mills operate on multiple axes, allowing intricate designs and features to be executed with high accuracy, making them indispensable in fields requiring detailed and precise component fabrication.
