Precision CNC Machining Services For Black Engineered Structural Parts
Precision CNC machining achieves the manufacturing of black engineered structural parts through three streamlined and logically linked steps:
1.Requirement Alignment for Post-Treatment Readiness
We lock in critical specifications—such as dimensional tolerances (±0.01mm) and surface roughness (Ra 0.8-3.2μm)—to ensure the part is prepared for subsequent black treatments (anodizing, black oxide, dyeing).
2.CNC Programming Adjustments for Blackening
Programs prioritize precision (±0.01mm) and surface quality: minimizing tool marks/burrs, controlling chip evacuation to prevent contamination, and using fillets on sharp edges. These adjustments ensure the machined surface serves as an ideal substrate for consistent blackening.
3.Material Selection Balancing Blackening and Performance
ISO-certified materials are chosen to balance both aspects:
- Metals: Aluminum (6061/7075) is suitable for anodizing and offers high strength; low-carbon steel (1018) is ideal for black oxide treatment, balancing machinability and corrosion resistance.
- Plastics: Nylon/PEEK can uniformly absorb dyes, providing toughness for lightweight structural needs.
