Aluminum CNC machining specialists
Precision Aluminum CNC Machining & Batch Production
CNCALPARTS is a dedicated CNC machining facility in Shenzhen, China, focused exclusively on aluminum components. From prototype transition and pilot runs to recurring production of 10 to 500+ units, we build repeatable processes for demanding industrial applications.
10–500+
Units per production run
±0.01 mm
Machining capability
3 / 4 / 5-axis
CNC machine platforms
Focused manufacturing
Dedicated aluminum expertise
Deformation control
Optimized workholding helps prevent warping in thin-walled housings and large plates.
Tooling optimization
Aluminum-specific cutting parameters support chip evacuation, cycle efficiency, and surface finish.
Anodizing readiness
Machining and preparation account for material removal and consistent clear, black, or hard anodizing.
Our workflow is calibrated for aluminum grades including 6061, 6063, 7075, 2024, and 5052. We do not machine steel, plastics, or other metals, allowing our technical resources, tooling, and quality systems to remain concentrated on aluminum.
Batch production system
A repeatable path from pilot run to stable supply
Transitioning from prototype to batch production requires a controlled process, not simply additional machine capacity. Our engineering team manages fixtures, machining rhythm, tool life, inspection, and documentation for consistent aluminum parts.
01
Fixture design
Dedicated workholding for repeat orders helps each batch meet dimensional requirements.
02
Cycle efficiency
Optimized tool paths and machining cycles reduce per-unit costs without sacrificing accuracy.
03
Tool management
Controlled tool life and replacement cycles support consistent surface roughness throughout production.
04
Traceable inspection
Standard inspection reports, FAI, and dimensional records support full batch traceability.
Technical specifications
Built for demanding component geometry
Our 3-axis, 4-axis, and 5-axis CNC machines support complex housings, deep-fin heat sinks, structural plates, and multi-sided components for robotics, optical equipment, and automation.

Applications and finishes
Complex parts, complete production support
- ●Enclosures and housings: Precision-fit lids and bases with integrated mounting features.
- ●Heat sinks: Deep-fin machining and complex cooling plate geometries.
- ●Structural components: Rigid brackets, frames, and mounting plates requiring high flatness and parallelism.
- ●Multi-sided machining: 5-axis capability reduces setups and improves position tolerances on complex housings.
Aluminum surface finishing
We manage post-machining finishes through in-house and partner capabilities.
Bead blasting
Uniform matte cosmetic finish.
Anodizing
Clear, black, and hard anodizing.
Brushing and polishing
Finishes tailored to aesthetic requirements.
Protective coatings
Powder coating and chromate conversion.
Quality assurance
Inspection at every production stage
Our inspection department uses CMMs, height gauges, micrometers, and surface roughness testers. For batch production orders, in-process inspections monitor critical dimensions, followed by a comprehensive final inspection report before shipment.
01 / In-process
Critical dimensions monitored during machining.
02 / First article
FAI and dimensional reporting support process approval.
03 / Final release
Parts are verified for immediate assembly upon arrival.
