CNC Milling 6061 Aluminum Drone Mounting Brackets | Secure & Anodized

These precision CNC milling mounting brackets are engineered to provide rock-solid attachment points for critical drone systems such as cameras, sensors, and communication modules. Machined from 6061-T6 aluminum and protected by a durable black anodized finish, they ensure long-term reliability under the combined stresses of vibration, shock, and harsh environmental exposure.

Project Overview

Project Name Heavy-Duty Drone Payload Mounting System
Material Aluminum 6061-T6
Processing Equipment High-Precision 3-axis Machining Center
Technology CNC Milling & Tapping
Testing Instruments CMM, Thread Gauges, Vibration Test Bench
Surface Treatment Black Anodizing (Corrosion & Wear Resistant)
Post-surface Inspection Equipment CMM, Adhesion Tester, Salt Spray Chamber (Sample)
Application Areas Aerial Surveying Drones, Agricultural UAVs, Security & Surveillance Platforms

Core Specifications & Performance

Characteristic Specification Standard / Purpose
Material 6061-T6 Aluminum ASTM B221, Excellent strength & machinability
Mounting Hole Position Tolerance ±0.05 mm (True Position) ASME Y14.5, Ensures precise component alignment
Thread Integrity (Tapped Holes) 100% Go/No-Go Gauge Tested ISO 965, Guarantees secure fastening
Anodizing Thickness & Hardness 18-25 µm, HV ≥ 400 MIL-A-8625 Type II, For abrasion resistance
Flatness (Mounting Surface) 0.1 mm / 100 mm Ensures even load distribution

Design & Functional Advantages

  • Optimized Stress Distribution: The bracket geometry is designed with finite element analysis (FEA) to eliminate stress concentrations, ensuring it can withstand high G-forces and landing impacts without failure.
  • Thermal Management Compatibility: 6061 aluminum's good thermal conductivity, combined with the anodized surface, helps dissipate heat from mounted electronics, improving system reliability.
  • Lightweight Yet Robust: CNC milling allows for strategic material removal, creating a bracket that is as light as possible while maintaining the stiffness and strength required to protect expensive payloads.

Quality-Focused Manufacturing Process

  • Raw material certification and inspection prior to machining.
  • Use of climb milling techniques for better surface finish and dimensional accuracy on critical edges.
  • Post-machining stress relief (if required by design) to ensure long-term dimensional stability.
  • Controlled anodizing process with racking designed to prevent coating buildup in threaded holes.

Comprehensive Quality Documentation

  • First-Article Inspection Report (FAIR) with full dimensional data.
  • Material Test Report (MTR) for traceability.
  • Anodizing Process Certificate with thickness and color consistency records.
  • Vibration test report available upon request for mission-critical applications.
