Aluminum focus
Built for difficult features
From prototypes to recurring batch production, our process is engineered around the behavior of aluminum alloys.
Why specialization matters
One material. A more controlled process.
General-purpose machine shops move between steel, titanium, brass, and plastic. Each material demands different cutting speeds, coolant types, tooling, and inspection methods. By focusing exclusively on aluminum, CNCALPARTS has refined tooling, workholding, deformation control, thermal management, and finishing around the alloys your parts require.
Deformation control
Manage internal stress in large, thin-walled components to reduce warping.
Chip evacuation
Optimize cutting parameters to prevent chip nesting in deep pockets.
Surface integrity
Control Ra values and prepare surfaces for anodizing and other finishes.
Thermal stability
Maintain tight tolerances despite aluminum's high thermal expansion coefficient.
Technical capabilities
Designed for complex aluminum parts
We combine 3-axis, 4-axis, and 5-axis CNC machining with CNC turning and turn-mill processes to manufacture precise housings, structural components, optical parts, and automation hardware.

Engineering for difficult geometries
Features that demand process discipline
Our machining strategies address the areas where complex aluminum components are most vulnerable to vibration, distortion, and stack-up error.
Thin walls and deep pockets
Specialized fixtures and incremental step-down machining help stabilize thin walls. Long-reach tooling and optimized chip-breaking geometries support deep pocket floor and wall finishes.
5-axis and multi-sided machining
Fewer setups reduce stack-up errors and improve the positional accuracy of holes, slots, and surfaces across multiple planes.
Precision holes and bores
We maintain hole tolerances down to ±0.01 mm while accounting for the gummy nature of 6061 and the high-strength characteristics of 7075.
Material expertise
The right alloy for the job
Our inventory and handling processes are specialized for the aluminum grades used in structural, optical, aerospace-inspired, and industrial applications.
6061 aluminum
Reliable general-purpose performance
The industry standard for structural parts, housings, brackets, and machined enclosures where balanced strength, machinability, and finishability are important.
7075 aluminum
High strength with lower weight
Selected for demanding applications where weight reduction, durability, and high strength are critical.
2024 aluminum
For fatigue-sensitive components
A practical choice for components requiring higher fatigue resistance and consistent dimensional performance.
5052 and 5083 aluminum
Weldability and corrosion resistance
Useful for fabricated or welded assemblies and applications where corrosion resistance is a priority.
Quality control
Measured from drawing review to final report
Before machining begins, our engineers review drawings for critical dimensions and potential manufacturing bottlenecks. Quality control continues throughout production and final inspection.
CMM verification
Coordinate measuring machines verify complex 3D geometry.
Surface inspection
Surface roughness testers confirm Ra requirements from 0.8–3.2 μm.
Dimensional documentation
Dimensional Inspection Reports and First Article Reports are available upon request.
Finishing options
Protective and cosmetic finishes
As machined
Standard CNC finish.
Bead blasting
Uniform matte cosmetic finish.
Anodizing
Clear, black, and color options.
Hard anodizing
Increased surface hardness.
Powder coating
Durable decorative protection for industrial components.
