Precision Aluminum Machining Services
At CNCALPARTS, we machine aluminum. Only aluminum. Our focused process is built around tight tolerances, controlled deformation, accurate hole locations, reliable flatness, and consistent surface quality for demanding technical components.
From rapid prototypes to repeat production, we support robotics, automation, optics, and electronics teams with precision-milled and turned aluminum parts.
One material, deeply optimized
Tooling, workholding, cutting parameters, and finishing preparation are tuned specifically for aluminum alloys.
Core capabilities
Built for precise, repeatable aluminum parts
Our Shenzhen-based facility supports 3-axis, 4-axis, and 5-axis milling, together with CNC turning and turn-mill machining. This range allows us to match the process to the geometry, tolerance, and production volume.
Production range
Rapid prototypes, low-volume programs, and batch production from piece 1 to 500+.

Why aluminum specialization matters
Control the details that define part performance
Aluminum can move, mark, burr, or finish inconsistently when it is processed without the right controls. Our workflow addresses these risks from setup through shipping.
Deformation control
Machining strategies for internal stress, large pockets, thin walls, and geometries where warping can affect flatness or alignment.
Surface integrity
Protection is integrated into handling and production to reduce scratches, burrs, and cosmetic variation on visible components.
Finish-ready machining
Machining allowances and process decisions account for anodizing so final dimensions and appearance remain consistent.
Optimized tooling
Aluminum-focused cutting parameters support chip evacuation, tool life, cycle efficiency, and repeatable batch quality.
Typical components
Made for technology-driven applications
We manufacture custom aluminum components where dimensional stability, clean surfaces, and controlled feature relationships are essential.
Enclosures & housings
Precision housings for electronics and industrial controllers.
Heat sinks
Thermal management components with tight flatness requirements.
Robotics & automation
Structural brackets, frames, and complex 5-axis components.
Precision turned parts
Shafts, spacers, and fittings with tight diametrical tolerances.
Optical mounts
High-precision components requiring strict parallelism and position control.
Quality assurance
Inspection is part of production
Every part is checked against your technical drawings and 3D models. Quality control is integrated into the production cycle rather than reserved only for final inspection.
Documentation available on request
Dimensional Inspection Reports and First Article Reports provide traceability for critical dimensions and production approval.
Pre-production review
Drawings are reviewed for tolerance feasibility and manufacturing optimization.
In-process checks
Height gauges, micrometers, and bore gauges help maintain process stability.
Final inspection
CMM inspection is used for complex geometries and critical dimensions.
Traceable reporting
Inspection and first article documentation can be supplied to support your quality requirements.
A practical production path
Support from first concept to repeat batch
01 / Prototype
Validate the design
Fast-turnaround prototypes support design evaluation, fit checks, and early performance testing.
02 / Low volume
Stabilize the process
Engineering feedback helps improve manufacturability, control risk, and reduce unnecessary cost.
03 / Batch
Repeat with confidence
Stable setups support consistent quality across production runs from piece 1 to piece 500+.
A focused material scope
We specialize exclusively in aluminum. If your project requires stainless steel, brass, or titanium, we are not the right fit. This focused scope allows us to provide deeper expertise in aluminum machining, finishing preparation, and process control.
