Case Study: CNC Machining & Anodizing Solution for a Complex Aluminum Assembly
A two-piece CNC machining strategy helped reduce machining complexity, avoid anodizing fixture marks, and improve final assembly quality.
The Challenge
Integrating the circular and square sections into a single CNC-machined part was technically possible, but it would have required significantly more machining time and material removal, resulting in much higher manufacturing costs. More importantly, because every surface was visible, conventional anodizing hanging methods would inevitably leave hanging marks on the cosmetic surfaces.
Solution
To improve manufacturability, we redesigned the production process by machining the two components separately. M5 threaded holes were incorporated into both parts, allowing us to develop dedicated M5 anodizing fixtures that securely held each component during surface treatment. This eliminated visible hanging marks while maintaining consistent anodizing quality across all exposed surfaces.
Result
After anodizing, the two components were assembled using custom M5 set screws, creating the appearance of a single integrated product. This approach significantly reduced machining costs, improved production efficiency, and delivered a clean, high-quality anodized finish without compromising the product's appearance.
- Project Outcome
- Better tool access
- Cleaner Anodized Appearance
- Reliable final assembly
CNC Machining Cost: What Determines Your Quote?

Part design complexity
Complex shapes, deep cavities, thin walls, and tight features require more machining time.
Material and machinability
Material type and hardness affect cutting speed, tool wear, and overall machining efficiency.
Tolerance requirements
Tighter tolerances require more controlled machining and additional inspection or finishing.
Surface finish
Additional finishes such as anodizing, plating, polishing, or blasting, add process steps.
Quantity and setup
Higher quantities reduce setup cost per part and improve overall unit pricing.
Delivery schedule
Shorter lead times may require priority scheduling, expedited sourcing, or additional resources.

Yes. HRCCNC supports one-off prototypes, small batches, and low-volume production projects. We can review your drawings and recommend a practical machining and production approach.
What tolerances can you support?
Tolerance support depends on material, part geometry, size, wall thickness, machining process, and inspection requirements. Please include critical dimensions and tolerance notes in your drawings.
Can you provide surface finishing after CNC machining?
Yes. Available finishing options may include anodizing, bead blasting, polishing, plating, powder coating, black oxide, and other post-processing services depending on material and part requirements.
Can you provide inspection reports or material certificates?
Dimensional inspection reports, material certificates, and other quality documentation can be provided upon request. Please mention documentation requirements before quotation.
How long does CNC machining usually take?
Lead time depends on part complexity, material availability, quantity, surface finish, inspection needs, and delivery requirements. Simple prototype projects are usually faster than complex or finished production parts.
