Defining the Standards of Modern Aviation

Q: How can aerospace fabricators prevent roll deflection and loss of geometric precision when forming ultra-tight radii across exceptionally long components like wing skins or keel beams?

Davi engineered the MAV AER Series variable axis 3-roll system specifically around a robust press-roll design equipped with anti-deflection beams and structural back-up rolls. This structural reinforcement completely offsets geometric deviations across lengths up to 12 meters (40 feet) while safely managing top roll diameters as small as 100 mm (4 inches).

Q: What rolling technology handles aerospace components that feature pockets or milled areas with non-uniform thickness without leaving marks on the material?

The Davi MAV AER Series utilizes an advanced variable axis technology that allows for dynamic, real-time adjustments of the roll positioning. The machine adapts layout adjustments instantaneously to thickness variations along the profile, balancing the pinch pressure dynamically.

Q: How can tier suppliers automate the production of complex, non-cylindrical aero-geometries like ovals and variable-radius engine nacelles while filling the operator skill gap?

Davi integrates its advanced proprietary CNC infrastructure with the automated AI-Vision radius measurement system. This combination maps thousands of points via high-definition laser scanning to calculate and adjust the rolling program automatically in real time.

Q: How do you prevent structural twisting and cross-sectional deformation when bending slender reinforcing stringers and bars for helicopter fuselages?

Davi offers the MC4P Series 4-roll angle roll machine designed explicitly for slender, high-precision profile bending. The fourth roll provides a dedicated, continuous clamping action that secures the profile firmly against the top roll during the entire deformation process.

The aeronautics industry demands perfection. Whether it’s rolling high-strength aluminum for a fuselage or titanium alloys for engine nacelles, the required tolerances are measured in hundredths of a millimeter. Davi is the world’s trusted partner for leading aircraft and helicopter manufacturers, providing specialized technology that handles complex, multi-radii shapes and ultra-tight diameters. From private jets to the largest commercial airliners, our machines are the silent force behind the wings of tomorrow.

Ultra-Tight Radii on Long Plates

solution:

Forming parts like wing skins or keel beams requires rolls with extremely small diameters (down to 100 mm / 4") combined with exceptional lengths (up to 12 m / 40 ft).

Varying Thickness & Pockets

solution:

Aerospace components often feature "pockets" or milled areas that create uneven thicknesses. Our variable axis technology allows for the real-time adjustment needed to manage these inconsistencies without marking the material.

Specialty Alloys and Complex Aero-Geometries

solution:

We provide dedicated surface treatments for rolls to prevent contamination and surface defects on sensitive materials like Aluminum, Titanium, and Stainless Steel. Our advanced CNC and AI-Vision systems enable the automated production of ovals, cones, and multi-radii shapes with absolute repeatability.
