CNC Turn Mill Aluminum Circular Flange Mounting Base OEM Precision Machining Parts
This is a custom CNC turn-mill machined aluminum rotary flange fixture with black anodized mounting base for industrial automated rotating equipment. Designed as high-precision rotary positioning assembly specially for robotic rotating jigs and testing rotary modules, it is manufactured from solid aluminum billets via integrated CNC turning, milling, drilling and black hard anodizing processes for the mounting base. It delivers stable rotary concentricity and anti-wear surface protection, widely used for automation rotating fixtures, optical inspection equipment and mechanical rotary transmission assemblies.
Made from high-strength aluminum alloy 6061/7075, it combines multi-hole annular rotary flange and grooved black mounting base with micron-level dimensional tolerance, eliminating rotation deviation and providing long-term wear resistance for continuous cyclic automated production.
Product Overview
Core CNC Composite Machining Technology
- Raw Material Selection We adopt solid aluminum alloy 6061 or 7075 billets for both base and circular flange. The material features lightweight, high structural rigidity, excellent machinability and customizable anodizing colors, ideal for precision fixture parts requiring repeated high-speed rotation.
- Dual-Part CNC Separate Machining Craft This assembly cannot be produced by stamping or casting, fully relying on CNC composite processing:
Step 1: Black Anodized Mounting Base Processing
- CNC flat milling to form outer contour, symmetrical side mounting grooves and internal positioning platforms;
- Precision drilling & tapping for fixed installation holes;
- Full deburring, followed by sandblasting + black hard anodizing to achieve scratch-resistant matte black surface.
Step 2: Annular Rotary Flange Processing
- CNC turn-mill composite machine one-time clamping to finish inner & outer stepped circular surfaces for high coaxiality;
- End face precision drilling of evenly spaced counterbore mounting holes;
- Fine finishing to control circular runout tolerance within ±0.002mm.
- Surface Treatment Options Standard finish: black hard anodizing for mounting base, natural silver machined finish for rotary flange; customizable sandblasting, clear anodizing, mirror polishing for both parts as customer drawing requirements.
- Full Precision Inspection Each finished assembly undergoes CMM coordinate measuring inspection to test base flatness, flange circular runout, hole position spacing and matching clearance between two parts, guaranteeing consistent precision for prototype and mass orders.
Product Advantages
- Full Customizable Structure: Adjust base size, groove layout, flange inner/outer diameter, hole quantity and surface treatment strictly per your 2D drawings or 3D STEP/IGS models.
- Ultra-High Rotary Precision: Separated CNC one-clamping processing eliminates secondary clamping errors, ensuring zero jitter under high-speed cyclic rotation.
- Wear-Resistant Anodized Base: Black hard anodized layer protects the fixed base from scratch and corrosion during long workshop use.
- Flexible Production Batch: Accept small prototype trial orders and large-volume mass production, all CNC machining and surface treatment finished in our factory to shorten lead time and control factory cost.
