Precision Billet Aluminum Machining Services
CNCALPARTS is a precision CNC machining facility based in Shenzhen, China, dedicated exclusively to the manufacturing of custom aluminum parts. We do not machine steel, plastics, or brass. By focusing solely on aluminum, we have optimized our tooling, cutting parameters, and workholding strategies to deliver consistent, high-quality components for global technology and manufacturing companies.
Expert Billet Aluminum Machining
We specialize in machining complex components from solid billet aluminum. Unlike casting or injection molding, billet machining offers superior structural integrity and material consistency, making it the standard for high-performance applications.
High Material Removal Rates (MRR)
Efficiently removing mass while maintaining structural stability.
Stress Management
Strategic roughing passes to release internal material stresses before final finishing, ensuring parts stay within tolerance.
Deformation Control
Specialized fixturing and tool paths designed to prevent thin-wall distortion and warping during the machining process.
Surface Integrity
Careful selection of feeds and speeds to achieve required Ra values and cosmetic finishes directly from the machine.
Manufacturing Capabilities
We provide a full range of CNC milling and turning services, tailored specifically to the properties of aluminum alloys.

Engineering for Complex Aluminum Parts
Aluminum requires a different approach than harder metals. We account for thermal expansion, chip evacuation, and material ductility in every program.
For complex geometries—such as deep pockets, thin-wall enclosures, or multi-sided housings—we engineer the manufacturing process to minimize setup changes. By utilizing 5-axis machining and optimized workholding, we reduce the risk of handling marks and alignment errors, ensuring that the final part matches the 3D model exactly.
Applications and Industries
Our components are found in high-precision industries where weight, conductivity, and structural stability are critical. Whether you require a single prototype for design validation or a batch of 500+ units for production, our workflow is designed to scale without sacrificing dimensional accuracy.
Robotics & Automation
Structural frames, sensor housings, and effector components.
Electronics & Optics
Heat sinks, cooling plates, camera housings, and optical mounts.
Industrial Equipment
Manifolds, brackets, and custom machine components.
Mobility
Enclosures and structural parts for drone and specialized vehicle systems.
Precision Surface Finishing
The final surface is often as important as the geometry. We offer in-house and managed finishing services to meet your specific requirements.
- As Machined: Clean, deburred surfaces directly from the CNC.
- Bead Blasting: Uniform matte finish for cosmetic consistency.
- Anodizing (Clear, Black, Color, Hard): Surface protection and aesthetics.
- Brushing & Polishing: Tailored for specific visual requirements.
- Powder Coating & Chemical Film: Additional protective layers for harsh environments.
Quality Assurance & Inspection
We review all drawings and 3D models before production starts to identify potential manufacturing challenges. Our quality control process includes:
Dimensional Verification
Use of CMM, micrometers, height gauges, and bore gauges to ensure features meet tolerances.
Process Control
First Article Inspection (FAI) for every new project and ongoing in-process checks for batch production.
Documentation
Provision of dimensional inspection reports upon request to ensure traceability and compliance with your internal standards.
Why Choose a Focused Aluminum Shop?
General machine shops often treat aluminum as just another material in their queue. At CNCALPARTS, our entire operation—from machine calibration to cutting tool selection—is built around aluminum.
This specialization allows us to master the nuances of 6000 and 7000 series alloys. We understand how these materials react to heat, how they behave during high-speed machining, and how to prepare them for optimal anodizing results. We do not machine other metals; this focus ensures that your aluminum parts are handled with the specialized attention they require.
