Assembling large aerostructures such as wings, sections of fuselages and stringers is one of the biggest technical and logistical challenges in the aeronautics industry. The need for extreme precision, repeatability, traceability and efficiency in ever more demanding production environments has led to the adoption of advanced automation solutions. In this context, companies such as Loxin, which is member of the Aritex group, are at the forefront of transformations in the sector with cutting edge robotic technologies.

Automating critical processes: drilling, riveting and positioning
Precision drilling is one of the most demanding processes in aeronautics assembly, especially when working with materials like titanium and composites. Loxin has developed robotic solutions that can carry out large diameter drilling (up to 50.8 mm) in one single run, while maintaining tolerances of ±0.2 mm. This level of precision was made possible thanks to integrating systems for force control, dynamic position offsetting and automatic quality verification.
Automated riveting is another key process. Instead of depending on operators for repetitive and physically demanding tasks, Loxin’s systems enable riveting to be carried out with checks on pressure, depth and alignment, thus guaranteeing uniformity in assembly. These solutions not only increase the quality of the assembly, they also minimise risks caused by human error and improve plant safety.
As for positioning of large components, Loxin employs laser measurement and machine vision systems that enable pieces of several metres in length to be aligned with pinpoint accuracy. This process takes on special importance when assembling fuselage sections or wings, where the slightest deviation can affect structural integrity.
Advanced robotic solutions: Tricept and multifunction end effectors
One very distinctive element in the solutions offered by Loxin is the modular robotic system driven by PKM Tricept hybrid parallel kinematics , which combines the stiffness of a machine tool and the flexibility of an industrial robot. This system is ideal for drilling and riveting in aeronautic structures, thanks to its capacity to move in five axes, high payload and great stability.
The Tricept can be integrated into automated lines with multifunctional heads tailor made for each application. The heads can include a wide range of tools: drills, MV inspection systems, clamps, contact measurements systems and even riveting modules. The versatility of this system enables several operations to take place without having to change any tools or station, optimising the cycle time and reducing the space occupied on the plant.
Process traceability and digitalisation
Traceability is a vital requirement in the aeronautics industry. Every operation needs to be documented, verified and available for internal and external audits. Loxin’s solutions include data collection systems that can log key parameters for each operation: position, force applied, drilling depth, temperature, etc. This data is stored in real time and can be integrated into the client’s MES or PLM systems.
Loxin also works with digital twin environments, which enables processes to be simulated before they are implemented, validating designs, optimising routes and predicting any potential interferences. Using advanced simulation reduces start-up times and improves the system’s overall efficiency.
Impact on efficiency, quality and sustainability
Automating the assembly of large aerostructures not only improves productivity, it also has a direct impact on the quality of the end product. Repeatability in automated processes reduces variability, improves structural reliability and makes certifying critical components that much easier.
From an operational perspective, Loxin’s solutions reduce cycle times, minimise rework and optimise the use of resources. All these advantages result in significantly improved operational efficiency and sustained long-term cost reductions.
Another benefit is that by reducing the need for heavy tools, energy consumption is reduced and workplace ergonomics are improved; these solutions also contribute to more sustainable and safer production.
Automating the assembly of large aeronautical aerostructures is now a tangible reality, driven by the need for improved efficiency, quality and traceability in a highly competitive sector. With the technological backup of the Aritex Group and Loxin’s specialised skills, we are developing automated solutions that respond with precision to the technical challenges of the aeronautical sector, integrating advanced robotics, machine vision, digital traceability and operational flexibility adapted to each client’s specific technical needs.
In an environment where every millimetre counts and every second matters, automation not only offers a competitive edge: it’s a necessary condition for being a leader in aeronautical manufacturing.
