High Precision CNC Turning Milling Aluminum Alloy Rotary Disc Flange Base Custom Automation Rotating Components
This is a custom CNC turn-mill machined aluminum rotary flange disc base for industrial rotating automation equipment. Designed as high-coaxiality rotary connection flange specifically for rotating mechanical assemblies, it is made from solid aluminum billets via integrated CNC turning and milling processes including stepped profile turning, curved surface finishing and counterbore hole drilling. It delivers excellent rotational concentricity and lightweight high-strength performance, widely used for robotic rotary joints, rotating testing equipment and transmission rotary connection modules.
Made from premium aluminum alloy 6061/7075, it features multi-layer coaxial stepped boss and evenly distributed mounting counterbores with ultra-tight tolerance, eliminating rotation shake and ensuring stable long-time continuous operation of rotary machinery.
Product Overview
Core CNC Turn-Mill Composite Machining Technology
- Raw Material Selection We use solid aluminum alloy 6061 or 7075 bar stock as raw material. This material features light weight, high rigidity, excellent machinability and natural corrosion resistance, which can effectively reduce rotary load without losing structural bearing capacity.
- Integrated CNC Turn-Mill Core Craft This rotary part cannot be produced by stamping or sheet metal, relying entirely on turn-mill composite machining: Step1: Single clamping completes outer circle, inner hole and multi-layer stepped boss precision turning to guarantee coaxiality; Step2: CNC finish turning for smooth transitional curved surfaces to reduce rotation friction; Step3: End face milling & drilling to process evenly distributed counterbore mounting holes in one setup; Step4: Fine finishing ensures dimensional tolerance within ±0.002mm.
- Deburring & Custom Surface Treatment All hole edges, stepped corners and curved surfaces are thoroughly deburred to remove tiny cutting burrs. Standard surface is bright machined finish; optional post-treatment includes mirror polishing, sandblasting, clear/hard anodizing as customer drawing demands.
- Full Precision Inspection Each finished flange disc undergoes full inspection by CMM coordinate measuring machine. We test coaxiality, circular runout, hole position spacing and flatness one by one to keep consistent precision for prototype samples and mass orders.
Product Advantages
- Fully Customizable Structure: Adjust disc diameter, stepped boss height, hole quantity and layout strictly according to your 2D drawings or 3D STEP/IGS files.
- Ultra-High Rotary Precision: Integrated turn-mill one-clamping processing avoids secondary clamping error, ensures outstanding concentricity with no high-speed rotation jitter.
- Flexible Production Batch: Accept small prototype trial orders and large-volume mass production, adjustable lead time for new rotating equipment development.
- One-Stop In-House Production: All processes from aluminum bar cutting, turn-mill composite machining to surface finishing are completed in our factory, controlling cost and delivery cycle efficiently.
