WindEnergy 2026

22-25 September 2026 | Hamburg, Germany

CNC Onsite exhibits at WindEnergy Hamburg 2026, 22-25 September at Hamburg Messe. You will find us on the Danish pavilion, The Pavilion Powered by Denmark, in hall B1.EG at stand B1.EG.508. We share the stand with other Danish companies and are listed as a separate exhibitor in the directory.

We machine and repair wind turbine components where they stand. Yaw rings, bolt threads, brake discs, generator shafts, blade roots and tower flanges are brought back to tolerance in place, so the component stays where it is and the crane stays on the ground.

Bring a damage report, a drawing or a photo. You will get a straight answer on whether we can machine it in place, and what it would take.

What to expect at our stand

Uptower repair

Yaw rings, bolt threads, brake discs and generator shafts machined back to tolerance inside the nacelle. No removal, no crane.

Blade root repair

Blade roots, root bushings and blade surfaces repaired on site.

Flanges and support structures

Tower flanges, monopile flanges and sea fasteners machined in place.

Measurement and alignment

Laser tracker, 3D scanning and Easy-Laser alignment, on the same visit as the machining.
