1. Material Superiority


Constructed from 6061 or 7075 aluminum alloy, the component benefits from the material’s high tensile strength, excellent machinability, and lightweight properties. 7075 alloy variants further provide enhanced hardness and fatigue resistance for heavy-duty applications, while 6061 alloy offers superior corrosion resistance and cost-effectiveness for general industrial use.


2. Precision Machining Process


• CNC Milling: Multi-axis CNC machining centers perform high-precision milling of cavities, contours, and flat surfaces, ensuring tight dimensional tolerances and smooth surface finishes (Ra ≤ 1.6μm).


• Drilling & Tapping: Computer-controlled drilling and tapping create accurately positioned threaded holes and counterbores, with thread precision meeting ISO 4H/5H standards for secure fastener engagement.


• Surface Finishing: Anodization (clear/color anodizing or hard anodizing) is applied to enhance corrosion resistance, wear resistance, and aesthetic appeal. Optional sandblasting or brushing processes further refine the surface texture for specific application requirements.


• Quality Verification: Coordinate Measuring Machine (CMM) and optical comparator inspections validate all critical dimensions, ensuring compliance with design specifications and industrial quality standards.


3. Application Scope


This component is widely utilized in automotive manufacturing fixtures, electronic equipment assembly jigs, aerospace component testing tools, and robotic automation systems. Its customizability allows it to be tailored to unique mechanical design requirements, making it a versatile solution for precision engineering across diverse industries.
