CNC Milling Capabilities

3-Axis CNC Milling — 25 Machines

Reliable 3-axis milling for prismatic parts, flat surfaces and straightforward geometries. Cost-effective for standard structural components and housings.

4-Axis CNC Milling — 5 Machines

4th-axis rotary capability for features on multiple sides without re-fixturing. Suitable for parts requiring operations on two or more faces.

5-Axis CNC Milling — 5 Machines

Simultaneous 5-axis machining for complex curved surfaces, deep cavities and multi-sided parts in a single setup. Reduced fixturing, improved accuracy and shorter lead times.

Milling Materials

Metals

Aluminum: 6061, 7075, 2024, 6082 — the most commonly milled material. Lightweight, excellent machinability.
Stainless Steel: 304, 316, 17-4PH, 303 — corrosion resistant, versatile for structural and precision parts.
Copper & Brass: H59, T2 — excellent conductivity for electrical connectors and terminals.

Plastics

ABS — prototyping and consumer housings
POM (Delrin) — precision mechanical components
PEEK — high-temperature industrial parts

Milling Tolerances

Critical tolerance control for milled parts: ±0.05mm
Tighter tolerance (e.g. ±0.01mm) can be evaluated based on your drawing requirements.

Machining Size Range

Axis	Maximum (per machine model)
X-axis	Up to 2000mm (large-format machines)
Y-axis	Up to 900mm
Z-axis	Up to 800mm

Actual machining size depends on machine model and part geometry. We will confirm feasibility in our quote.

Surface Finishing for Milled Parts

Anodizing — most popular for aluminum milled parts; available in clear, black and custom colors
Sand Blasting — uniform matte finish before anodizing or painting
Brushing — decorative directional lines on visible surfaces
Plating — nickel or chrome plating for wear and corrosion resistance
Polishing — mirror finish on precision surfaces
Painting — custom color matching for brand requirements
Silk Screen — logos, labels and markings on finished parts

Quality Assurance

Every milled part undergoes our 5-step inspection process: incoming material inspection, first article inspection (FAI), in-process inspection, final inspection and outgoing inspection.

We Provide

First Article Inspection (FAI) reports
Dimensional inspection reports
Material certificates
Surface roughness and hardness measurements

Tolerance Commitment: We commit only to tolerances within our verified capability. Critical tolerance control: ±0.05mm. Tighter tolerance can be evaluated per drawing.

CNC Milling FAQs

What is the difference between 3-axis, 4-axis and 5-axis milling?

3-axis milling moves the cutting tool along X, Y and Z axes — suitable for flat surfaces and simple geometries. 4-axis adds a rotary axis for multi-sided parts. 5-axis enables simultaneous movement along all five axes, allowing complex curved surfaces and multi-sided features in a single setup.

What materials can you mill?

We commonly mill aluminum (6061, 7075, 2024, 6082), stainless steel (304, 316, 17-4PH, 303), copper and brass (H59, T2), and engineering plastics including ABS, POM and PEEK. Custom materials available upon request.

What tolerances can you achieve with CNC milling?

Critical tolerance control down to ±0.05mm. Tighter tolerance (e.g. ±0.01mm) can be evaluated based on your drawing requirements.

What is the maximum part size you can mill?

Our maximum machining capacity is 2000×900×800mm. Actual capacity depends on part geometry and machine model — we will confirm feasibility in our quote.
