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, and anodized components require attention to dimensions and surface condition.
Because aluminum is our only material focus, these are the manufacturing challenges CNCALPARTS works with every day.
Deformation Control
Stable setups and controlled material removal for thin walls and large pockets.
Tight Tolerances
Precision dimensions down to ±0.01 mm with flatness and parallelism control.
Surface Finish
Ra 0.8–3.2 µm finishes with anodizing and bead blasting preparation.
Repeatability
Stable production from prototype quantities through recurring batch orders.

Finishing Options
As Machined
Natural CNC machined surface.
Bead Blasting
Uniform matte finish, often used before anodizing.
Anodizing & Hard Anodizing
Clear, black, and color anodizing for appearance and surface protection, plus hard anodizing for wear resistance.
Brushing & Polishing
For parts requiring specific cosmetic finishes.
Powder Coating & Conversion Coatings
Durable decorative and protective coatings, including chemical film and chromate conversion.
Why CNCALPARTS?
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.
Quality Control
CMM, height gauges, micrometers, calipers, thread gauges, and surface roughness testers with inspection reports on request.
Prototype to Production
Fast prototypes for design evaluation, then stable setups and repeatable inspection for low-volume and batch production.
Complex Machining
Multi-sided, thin-wall, deep pocket, precision bore, and 5-axis machining for demanding aluminum components.
Engineering Communication
Send STEP or STP files with PDF drawings and we will review tolerances, surfaces, and inspection needs before production.
