Focused on Aluminum
Aluminum machining requires careful control of cutting conditions, chip evacuation, workholding, heat, and deformation. Because aluminum is our only material focus, these are the manufacturing challenges we work with every day.
- Common grades: 6061, 6063, 6082, 7075, 2024, 5052, 5083
- Thin-wall, deep pocket, and cosmetic surface machining
- Anodizing preparation and surface finish control
- Inspection reports: dimensional and first article
Custom Aluminum Parts We Manufacture
CNCALPARTS supports aluminum machining from early prototypes to recurring production. Parts are manufactured according to customer drawings, 3D models, tolerances, surface requirements, and application needs.
Enclosures & Housings
Aluminum enclosures, housings, motor and camera housings, and electronics casings with clean cosmetic finishes.
Heat Sinks & Cooling Plates
Thermal management components with controlled fin geometry, flatness, and surface condition for bonding.
Brackets, Plates & Frames
Structural and mounting components machined to tight flatness, parallelism, and position tolerances.
Manifolds & Machine Components
Fluid and pneumatic manifolds, precision bores, threaded features, and multi-sided machined parts.
Robotics & Automation Parts
Robot components, fixtures and jigs, optical mounts, and precision turned parts for technology-driven industries.
Thin-Wall & Complex 5-Axis Parts
Minimum wall thickness from 0.5 mm, complex geometry, and multi-axis machining with deformation control.
Prototype to 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.
Every project is reviewed for drawings, tolerances, critical dimensions, surface requirements, and inspection needs before production begins.

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.
