Precision Lightweight 6061 Gimbal Frame with Hollow Structure and Deep-Hole Position Control

We successfully manufactured a precision lightweight 6061 aluminum hollow gimbal frame for a UAV gimbal system application. This complex structural component presented significant machining challenges — including upper-to-lower center boss coaxiality control, multi-directional U-slot positioning accuracy, deep-hole position tolerance management, and thin-wall edge deformation prevention during drilling operations. Through optimized machining sequences, custom toolpath strategies, and precision fixturing, we delivered dimensionally stable gimbal frames meeting all geometric and positional requirements.

Project Overview

Key Technical Highlights

• Precision Coaxiality Control: Achieved ≤0.015mm coaxiality between upper and lower center bosses through single-setup machining with precision fixturing, ensuring accurate alignment for bearing and shaft installation in the gimbal assembly.
• Multi-Directional U-Slot Machining: Precision milling of multi-directional U-slots with ±0.02mm positional accuracy using optimized toolpath strategies and specialized tooling, enabling precise component mounting and cable routing paths.
• Deep-Hole Position Management: Implemented staged deep-hole drilling strategies with precision spot-drilling and peck-drilling cycles, maintaining ±0.02mm position tolerance across deep-hole features without tool deflection or wander.
• Thin-Wall Edge Protection:
  • Backed Drilling Support: Custom fixturing with sacrificial backing supports thin-wall sections during drilling, preventing edge burring, deformation, and collapse.
  • Optimized Drilling Parameters: Controlled feed rates and specialized drill geometries minimize cutting forces on thin-wall sections, eliminating edge roll-over and burr formation.

Quality Verification

Each component underwent comprehensive inspection using CMM measurement for coaxiality (≤0.015mm), U-slot positioning accuracy (±0.02mm), and deep-hole position verification, supplemented by visual and microscopic inspection of thin-wall hole edges to confirm burr-free, deformation-free conditions.
