Focused on Aluminum
Aluminum machining requires careful control of cutting conditions, chip evacuation, workholding, heat, and deformation. Thin walls can distort, large pockets can release internal stress, cosmetic parts require careful handling, and anodized components require attention to dimensions and surface condition.
Because aluminum is our only material focus, these are the manufacturing challenges we work with every day. That focus shapes our tooling choices, cutting parameters, fixture design, and inspection routines.
We machine aluminum. Only aluminum.
Custom Aluminum Parts
We manufacture a wide range of custom aluminum components according to customer drawings, 3D models, tolerances, surface requirements, and application needs.
- Aluminum enclosures and housings
- Heat sinks and cooling plates
- Brackets, plates, and frames
- Motor and camera housings
- Manifolds and machine components
- Fixtures and jigs
- Robotics and automation parts
- Optical equipment components
- Precision turned parts
- Thin-wall and 5-axis parts
From Prototype to Production
CNCALPARTS supports aluminum machining from early prototypes to recurring production. For prototypes, we focus on fast manufacturing and design evaluation. For low-volume and batch production, we focus on stable setups, efficient machining, repeatability, and consistent inspection.
Stage 01
Prototype
1–10 pcs for design validation, fit checks, and fast iteration cycles.
Stage 02
Low Volume
10–500 pcs with stable setups, dedicated fixtures, and repeatable results.
Stage 03
Batch Production
500+ pcs with consistent inspection and recurring order support.
Precision & Complex Machining
- Tight tolerance machining
- 3-axis, 4-axis, and 5-axis machining

Aluminum Surface Finishing
- As Machined
- Natural CNC machined surface.
- Bead Blasting
- Uniform matte finish, often used before anodizing.
- Anodizing
- Clear, black, and color anodizing for appearance and surface protection.
- Hard Anodizing
- For applications requiring greater surface hardness and wear resistance.
- Brushing & Polishing
- For parts requiring specific cosmetic finishes.
- Powder Coating
- Durable decorative and protective coating.
Quality Control
We review drawings, tolerances, critical dimensions, surface requirements, and inspection needs before production. During machining and final inspection, parts are measured using equipment such as CMMs, height gauges, micrometers, calipers, bore gauges, pin gauges, thread gauges, and surface roughness testers.
Inspection reports, including dimensional inspection reports and first article reports, can be supplied according to project requirements.
Why CNCALPARTS?
We take a focused approach to CNC machining. Instead of processing many different materials, we specialize in aluminum and continuously improve our machining processes around one material category.
This focus supports better understanding of aluminum alloys, tooling, workholding, deformation control, surface finish, anodizing, and production consistency.
We machine aluminum. Only aluminum.
Single-Material Expertise
Tooling, cutting parameters, and fixtures optimized for aluminum alloys only.
Deformation Control
Thin walls, large pockets, and cosmetic surfaces handled with proven strategies.
Anodizing Ready
Dimensions and surface condition prepared for clear, black, color, and hard anodizing.
Engineering Communication
DFM feedback, drawing review, and responsive support from prototype to repeat orders.
