High Precision 5 Axis CNC Machining Aluminum Alloy Rotary Positioning Disc Custom Automation Rotating Jig Component
This is a custom 5-axis CNC turn-mill machined aluminum rotary positioning disc for industrial automation rotating fixture systems. Designed as high-coaxiality rotary jig base specially for automated rotating assembly stations, it is fabricated from solid aluminum billets via integrated 5-axis CNC turning and milling processes including concentric stepped turning, curved cavity profiling, counterbore drilling and peripheral positioning claw forming. It provides ultra-stable rotary positioning precision and lightweight high-rigidity structure, widely applied for robotic rotary fixtures, rotating precision testing equipment and automated transmission positioning modules.
Made from high-strength aluminum alloy 6061/7075, it features multi-layer coaxial boss, deep annular cavity and integrated outer positioning claws with micron-level dimensional tolerance, eliminating rotation offset and supporting long-term continuous cyclic operation of automated rotary equipment.
Product Overview
Core 5-Axis CNC Turn-Mill Composite Machining Technology
- Raw Material Selection We select solid 6061 or 7075 aluminum alloy bar as raw material. The material combines low density, high structural rigidity and superior machinability, greatly lowering rotary load without sacrificing bearing strength, and possesses natural anti-corrosion property for long workshop service life.
- One-Clamping 5-Axis Composite Machining (Core Craft) This complex rotary jig cannot be manufactured by stamping, casting or simple 3-axis machining, fully relying on 5-axis turn-mill center: Step1: Single clamping completes all outer circle, inner hole and multi-layer stepped boss precision turning to guarantee ultra-high coaxiality; Step2: Multi-angle linkage milling to shape deep curved annular cavity and three peripheral positioning claws in one processing cycle; Step3: End face precision drilling to produce evenly distributed concentric counterbore mounting holes; Step4: Fine finishing to control overall dimensional tolerance within ±0.002mm.
- Deburring & Custom Surface Treatment All cavity inner walls, hole edges, stepped corners and positioning claw contours undergo full manual deburring to remove micro cutting burrs. Standard surface is raw CNC silver machining finish; optional post-treatment includes mirror polishing, sandblasting, clear or hard black anodizing per customer drawing requirements.
- Full Precision Dimensional Inspection Each finished rotary disc passes comprehensive inspection via CMM coordinate measuring machine. We test circular runout, coaxiality, hole position spacing and positioning claw symmetry one by one to maintain consistent precision for prototype samples and mass bulk orders.
Product Advantages
- Full Drawing Customization: Adjust disc diameter, cavity depth, boss height, hole layout and positioning claw size strictly based on your 2D drawings or 3D STEP/IGS models.
- Ultra-High Rotary Positioning Accuracy: One-time 5-axis clamping eliminates secondary clamping errors, ensuring zero jitter during high-speed rotary cyclic operation.
- Flexible Production Batch: Accept small-batch prototype trial orders and large-volume mass production, adjustable lead time for new automation equipment development projects.
- One-Stop In-House Manufacturing: All production links from aluminum billet cutting, 5-axis turn-mill composite machining to surface finishing are completed in our factory, enabling strict cost and delivery cycle control.
