CNC Milling Services for Custom Parts

We utilize state-of-the-art 3-axis, 4-axis, and 5-axis CNC milling centers to transform your designs into highly accurate parts from a wide range of plastics and metals.

Our CNC Milling Capabilities

• 3-Axis Milling Services — Cost-effective, standard CNC milling for parts without complex multi-angle features. Best for flat parts, plates, brackets, housings, pockets, and simple prismatic components.
• 4-Axis Milling Services — Multi-sided machining in a single setup. Best for parts with side features, cylindrical profiles, cam-like forms, and multi-sided details.
• 3+2-Axis Milling Services — Enables complex features with stable machining and efficient setups. Best for angled holes, inclined faces, and multi-face components.
• 5-Axis Milling Services — Workpiece access from any angle with exceptional precision for impellers, aerospace parts, and other highly complex curved-surface components.

Advantages of CNC Milling

• Accelerated Speed-to-Market & Short Lead Times — Move from digital 3D models to finished parts in hours, without costly tooling.
• Superior Precision & Structural Integrity — Tight tolerances within ±0.005mm; native mechanical strength and thermal properties are preserved.
• Complex Geometries in a Single Setup — Multiple axes reduce manual re-clamping, lower cumulative errors, and reduce labor cost.
• Optimized Material Yield & Cost Efficiency — Smart tool engagement and short cycle times for a competitive cost-per-part across low- to high-volume runs.

Design Tips for Cost-Effective Milling Parts

• Use Practical Internal Corner Radii — Cutting tools are round; sharp internal corners are not possible.
• Avoid Extremely Deep, Narrow Pockets — Long tools reduce rigidity, increase cycle time, and affect surface finish.
• Keep Wall Thickness Reasonable — Thin walls may flex, especially in aluminum and plastics.
• Mark Cosmetic and Functional Surfaces — Identify visible surfaces, sealing faces, mating areas, and critical hole patterns.

FAQ

Is 5-axis machining always the best choice?
Not necessarily. While 5-axis machining is highly capable, 3-axis or 4-axis machining may be more economical for simpler parts. The ideal choice depends on your part geometry and requirements.

What materials can be CNC milled?
CNC milling can process aluminum, steel, stainless steel, brass, copper, titanium, ABS, POM, nylon, PC, PMMA, PEEK, PTFE, and many other engineering materials.

Can CNC milling make production parts as well as prototypes?
Yes. CNC milling is suitable for rapid prototypes, functional test parts, fixtures, bridge production, and low- to medium-volume end-use parts.

Can surface finishes affect part dimensions?
Yes. Anodizing, plating, powder coating, and painting can change surface dimensions. Critical fits, threads, and sealing areas should be identified before production.

Do I need both a 3D model and a 2D drawing?
A 3D model is preferred for geometry review. A 2D drawing is strongly recommended for tolerances, threads, surface roughness, cosmetic requirements, and inspection criteria.
