Typical Part Characteristics
Small outer dimensions
Thin walls or narrow slots
Fine holes and small threads
Tight dimensional consistency in batch production
These parts require controlled cutting parameters and experienced operators.
Aluminum Grades for Small Parts
For CNC small aluminum parts, we commonly use:
Aluminium 6061-T6 – balanced strength and machinability
Aluminium 7075 – high strength for compact structural parts
Aluminium 5052 – good corrosion resistance for thin sections
Material selection is optimized based on part size and function.
Machining Focus
Our CNC process for small aluminum parts emphasizes:
Precision milling for miniature profiles
Stable turning for small-diameter parts
Micro drilling and tapping
Burr control and edge protection
This ensures clean edges and reliable assembly performance.
Surface Treatment for Small Components
Surface finishing is adapted specifically for small aluminum parts:
Fine anodizing for uniform appearance
Light polishing for functional surfaces
Sandblasting for matte texture
Natural oxidation for cost-sensitive parts
Special care is taken to avoid surface damage during finishing.
Common Applications
CNC small aluminum parts are widely used in:
Electronic and electrical components
Sensors and precision devices
Automation and robotic assemblies
Compact mechanical structures
Custom-designed industrial parts
