The component shown is a lightweight aluminum 7075 CNC machined gimbal arm for a 3-axis drone gimbal system. The component shown is a lightweight aluminum 7075 gimbal arm for a 3-axis drone gimbal system. To reduce rotational inertia, the design features a complex curved profile with extensive material removal (pocketing). The manufacturing objective was to achieve a high stiffness-to-weight ratio while maintaining tight tolerances on the bearing bores to ensure precise camera stabilization.

Part type: Gimbal Arm

Material: Aluminum 7075-T6

Critical Tolerance: ±0.05mm

Quantity: 100 pcs

Lead Time: 15 day

Due to the component’s curved geometry and undercut features, a 5-axis CNC machining center was utilized. This setup allowed for continuous tool access to the complex outer profile and the internal cable routing channels without multiple re-fixturing steps, ensuring better geometric alignment between the mounting base and the motor housing.

Following the milling process, a fine boring operation was conducted to achieve the specified tolerance. This ensures a precise interference fit for the gimbal motor.
