5-axis CNC machined complex aluminum component

Dedicated Aluminum Manufacturing

We do not process steel, titanium, or plastics. By limiting our production to aluminum alloys—including 6061, 7075, 5052, and 6082—we have optimized our tooling, workholding, and thermal management specifically for this material.

Tight Tolerances

Our aluminum-only focus lets us hold tolerances down to ±0.01 mm on demanding features and mating surfaces.

Stress & Deformation Control

We actively manage internal stress and deformation common in thin-wall aluminum components throughout machining.

5-Axis Design Guide for Complex Aluminum Parts

5-axis machining is not just for complex geometries; it is a tool for increasing dimensional accuracy and reducing production costs. When designing for our 5-axis systems, consider the following principles.

Integrated Features

Utilize the 5-axis capability to machine multi-sided features in a single setup. This eliminates the tolerance stack-up associated with flipping parts between multiple operations.

Tool Accessibility

Use 5-axis milling to access deep pockets or inclined holes that are unreachable with 3-axis systems. Ensure that internal radii are compatible with standard tool diameters to minimize custom tooling costs.

Reduced Workholding

By orienting the part to the tool, we can machine complex shapes with minimal clamping. This is critical for thin-wall enclosures where excessive clamping force can induce part distortion.

Surface Finish Control

Continuous 5-axis toolpaths provide superior surface finish on contoured surfaces compared to the "stepped" results of 3-axis indexing.

From Prototype to Production

We support the full product lifecycle. Our prototype service focuses on rapid manufacturing and design verification to help you iterate quickly. For low-volume and batch production, we transition to stable, repeatable setups that ensure consistent quality across hundreds or thousands of units.

Whether you need a single precision housing or a production run of structural brackets, our workflow is tailored to your volume requirements.

Prototyping

Rapid manufacturing and design verification to help you iterate quickly on complex aluminum geometry.
Low-Volume Production

Stable, repeatable setups that hold quality from the first article through the full batch.
Batch Production

Consistent output across hundreds or thousands of units, aligned to your volume requirements.

Precision Surface Finishing

Aluminum requires specific surface treatments to meet functional and cosmetic requirements.

Anodizing

Clear, black, color, and hard anodizing for wear resistance and corrosion protection.

Mechanical Finishes

Bead blasting, brushing, and polishing to achieve specific aesthetic results.

Protective Coatings

Chemical film, chromate conversion, and powder coating for enhanced environmental durability.

Quality Assurance and Reporting

Precision is verified in-house. We utilize CMMs, height gauges, micrometers, and specialized bore/thread gauges to confirm every dimension against your technical drawings.

Every order includes a dimensional inspection report, and we provide First Article Inspection (FAI) reports for production batches to guarantee that the first part meets the same standard as the last.

Partnering with CNCALPARTS

We work with equipment manufacturers, robotics companies, and automation integrators who require consistent quality and clear engineering communication. By focusing solely on aluminum, we provide a level of technical depth that general machine shops cannot match. If you are looking for a reliable manufacturing partner for your aluminum components, we are ready to assist.
