CNC Milling Service
What Is CNC Milling?
CNC milling is a precision machining process where a rotating tool removes material from a fixed workpiece under computer control. By moving the cutter along multiple axes, milling can produce flat surfaces, precise pockets, slots, and even complex 3D contours.
This process is widely used for prototypes, jigs, and fixtures, and full-scale production components where accuracy and surface finish matter.
If your design has pockets, slots, or multiple flat faces, CNC milling is the process you need.

Stainless Steel (304, 316L) | High strength, corrosion and heat resistance, hygienic surface | Medical devices, food processing equipment, marine parts |
Steel (Mild, Alloy Tool Steel) | Very strong and durable, suitable for wear parts and tooling | Machine components, shafts, mold bases |
Copper & Brass | Excellent conductivity, good corrosion resistance, easy to machine | Electrical contacts, heat sinks, decorative parts |
Titanium | Exceptional strength-to-weight ratio, biocompatibility, corrosion resistance | Aerospace structural parts, medical implants, high-performance components |
POM (Delrin®) | Low friction, excellent dimensional stability, easy to machine | Gears, bushings, mechanical components |
Nylon (PA6, PA66) | Tough, wear-resistant, lightweight | Bearings, structural components, fixtures |
PEEK | High temperature resistance, chemical resistance, and excellent mechanical properties | Aerospace, automotive, medical, and semiconductor parts
|
ABS / PC | Affordable, impact-resistant, easy to prototype | Enclosures, low-volume prototypes, test fixtures |
Surface Finishes
Finish | Description |
|---|---|
As-Milled | Standard machined surface with visible tool marks. Ideal for functional prototypes or internal parts where appearance is not critical. |
Bead Blasting | Creates a uniform matte surface, removes machining marks, and improves appearance—great for consumer-facing parts. |
Anodizing (Type II / III) | Adds corrosion resistance and color options. Type III hard anodizing increases surface hardness for wear resistance. |
Powder Coating | Durable, decorative finish available in many colors. Suitable for enclosures and end-use products exposed to harsh environments. |
Electroplating | Adds protective or decorative metal layers (nickel, chrome, zinc) to improve appearance and corrosion resistance. |
Polishing & Buffing | Produces a smooth, reflective surface finish, commonly used for aesthetic components or optical parts. |
Silk-Screen Printing | Adds logos, part numbers, or labels directly to parts for easy identification. |
Laser Engraving / Etching | Permanent marking method for serial numbers, barcodes, or branding—ideal for traceability. |

CNC Milling vs. CNC Turning
CNC turning and CNC milling are both essential machining processes, but they’re used for different types of parts. Turning is the go-to choice for cylindrical components like shafts, bushings, pins, and threaded parts. The workpiece spins while a cutting tool removes material, giving you excellent roundness and concentricity.
Milling, on the other hand, is better suited for flat faces, pockets, and complex 3D features. The cutting tool rotates while the part stays in place, allowing you to create slots, contours, and multi-face features in a single setup.
Many projects actually require a combination of both. If your part needs turning service for its outer profile and milling service for features like keyways or drilled holes

FAQ's
We typically achieve tolerances as tight as ±0.01 mm (±0.0004 in) on critical features, depending on part geometry and material. Every batch is verified using a CMM (Coordinate Measuring Machine) to ensure dimensional accuracy and consistency. If your project requires special tolerances, we can review your CAD files and confirm feasibility before production.
We work with a wide range of metals—including aluminum (6061, 7075), stainless steel (304, 316L), mild steel, copper, brass, and titanium—as well as engineering plastics such as POM (Delrin®), Nylon, PEEK, ABS, and PC.
Material certifications and RoHS/REACH compliance can be provided on request to meet industry requirements.
Prototype CNC milled parts can ship in as little as 2–3 business days after order confirmation.
Low-volume production runs are typically completed within 5–7 business days, while high-volume orders follow a scheduled production plan.
Expedited services are available—just let us know your deadline, and we’ll prioritize your order.
