2026-03-18In modern aircraft manufacturing, drilling is one of the core processes in assembly. A large commercial airliner requires more than 2 million holes, and their positional accuracy, hole diameter consistency, and quality directly determine structural strength, aerodynamic performance, and service life.
Traditional manual and semi-automatic drilling methods face three major pain points:
1、Difficulty in curved surface positioning: The aircraft fuselage skin features complex double-curved surfaces, making manual positioning prone to deviation.
2、Poor process consistency: Differences in operating techniques among workers lead to fluctuations in hole quality.
3、Efficiency bottleneck: Long time consumption per hole makes it difficult to meet flexible production requirements.
How do we break through?
independently developed the Lightweight Automated Drilling Solution, designed specifically for high-precision, high-flexibility assembly scenarios in aerospace. It has been successfully applied in projects including domestic large aircraft, general aviation, and low-altitude vehicles.
Detailed Technical Highlights:
1. Real-time pose compensation system based on laser tracking + visual guidance, dynamically correcting workpiece deformation and clamping errors, with drilling position accuracy up to ±0.1 mm;
2. Modular end effector + autonomous path planning algorithm, enabling fast adaptation to different aircraft models and skins with varying curvatures (e.g., wings, tail fins, cabin doors);
3. Integrated axial force closed-loop feedback and speed-feed coordinated control, avoiding typical composite material defects such as burrs, delamination and ablation;
4. Lightweight robotic arm (<30 kg) with flexible deployment, supporting single-person operation, eliminating the need for large fixed tooling, and greatly reducing production line transformation costs;
5. Each hole generates a unique ID, recording position, parameters and images, seamlessly connected to the MES system to meet aviation quality traceability requirements.
Why choose the “lightweight” approach?
1.Low investment cost: No foundation modification required, deployment cycle shortened by 60%;
2.High production line flexibility: Rapid reconfiguration with product switching, supporting “multi-model parallel” production;
3.Friendly human-machine collaboration: Retains the flexibility of manual intervention, balancing efficiency and safety.
From “manual drilling” to “intelligent hole making”, this represents not only an upgrade in tools, but also a crucial step for China’s aviation manufacturing industry toward digitalization, flexibility and independent control.
Jingshi Hangke will continue to focus on fully self-developed intelligent assembly technologies for aviation, supporting the industrial chain security and high-quality development of domestic large aircraft.
