Focused on Aluminum Machining
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 demand careful handling, and anodized components need attention to dimensions and surface condition.
Because aluminum is our only material focus, these are the manufacturing challenges we work with every day. Explore the capability articles below to see how CNCALPARTS approaches each machining discipline.
Core Machining Capabilities
CNC milling, CNC turning, multi-axis machining, precision drilling, tapping, boring, and complex aluminum component manufacturing — all delivered with documented inspection.
3-Axis CNC Milling
Reliable milling for housings, plates, brackets, and frames with tight tolerances and consistent surface finish.
4-Axis & Multi-Sided
Indexing and multi-sided machining reduce setups, improve positional accuracy, and shorten lead times.
5-Axis Complex Geometry
Contoured surfaces, deep pockets, and complex aluminum components machined in fewer operations.
CNC Turning & Turn-Mill
Precision turned parts up to Ø300 mm, with turn-mill machining for combined features in one setup.
Thin-Wall & Deep Pocket
Minimum wall thickness down to 0.5 mm with deformation control and stress-aware machining strategies.
Finishing & Anodizing
As machined, bead blasting, brushing, polishing, clear, black, color, and hard anodizing, plus powder coating.
Custom Aluminum Parts We Manufacture
Parts are manufactured according to customer drawings, 3D models, tolerances, surface requirements, and application needs.
