Precision 6061 Circular Gimbal Adapter Base with Nano-Coating and Coaxiality Control

We successfully manufactured a precision 6061 aluminum circular gimbal adapter base with light gold nano-coating for an industrial UAV EO/IR payload rotation system application. This precision rotation interface component features concentric inner and outer ring structures with ribbed cavity sections — presenting significant machining challenges including stringent inner-outer ring coaxiality requirements and dead-corner deburring in confined rib cavities. Through single-setup precision machining, custom tooling strategies, and specialized deburring techniques, we delivered rotation-ready adapter bases with consistent geometric accuracy and clean internal features.

Project Overview

Key Technical Highlights

• Precision Ring Coaxiality Control: Achieved ≤0.01mm inner-outer ring coaxiality through single-setup machining with precision boring operations on both concentric ring features — ensuring accurate rotation axis alignment for smooth gimbal payload rotation.
• Process Innovation:
  • Single-Setup Concentric Machining: Inner and outer ring features machined in the same fixturing setup with precision boring, eliminating re-fixturing errors that compromise coaxiality.
  • Rib Cavity Dead-Corner Deburring: Specialized deburring tools and techniques reach confined internal corners in ribbed cavity sections — ensuring burr-free internal geometries without damaging adjacent surfaces.
  • Custom Toolpath Strategies: Optimized contouring toolpaths for ring features maintain consistent wall thickness and geometric integrity throughout machining.
• Surface Quality:
  • Precision finishing achieves Ra≤1.6μm surface finish on bearing and interface surfaces.
  • Light Gold Nano-Coating: Advanced nano-coating technology provides uniform thin-film protection with distinctive light gold aesthetic finish — offering enhanced corrosion resistance, wear protection, and consistent decorative appearance.

Quality Verification

Each component underwent comprehensive inspection using CMM measurement for coaxiality (≤0.01mm), dimensional accuracy (±0.015mm), and flatness (≤0.01mm), supplemented by surface roughness testing (Ra≤1.6μm), visual inspection of rib cavity deburring, and coating finish verification.
