Liebherr-Verzahntechnik GmbH have revised and further developed their rotary loading system (RLS) for automated and order-specific machine loading. Offering an additional load category for transportation weights up to 2,000 kilograms, greater storage density and wider interference diameters, the automation specialist is able to meet current manufacturing requirements. The new version will be presented at EMO 2025 in Hanover (Germany).
Liebherr-Verzahntechnik GmbH has expanded and increased the adaptability of its production of sophisticated machined parts for Airbus Aerostructures with an intelligent automation concept. At the Varel site in northern Germany, two pallet handling systems (PHS), a robot cell and a tool handling system (THS) work together seamlessly to supply three machining centers and other connected system components with the parts they need at all times.
In the new version of its bin picking software LHRobotics.Vision, Liebherr-Verzahntechnik GmbH relies on artificial intelligence (AI). By filtering irrelevant image data, it detects disordered workpieces faster and more accurately when removing them from the container.
Liebherr-Verzahntechnik GmbH is continuing the systematic development of its platform strategy with the redesign of its machine platform for workpieces up to two metres in diameter. The new series encompasses all relevant gear technologies and is aimed at manufacturers of large gears, particularly in the mechanical engineering, marine propulsion, construction machinery and wind power industries. The lineup begins with hobbing and profile grinding machines designed for this size range – making it possible, for the first time, to perform precision hard machining on large workpieces.

Hard-fine machining II – quality and efficiency for internal gears
SkiveFinishing® is a new method for efficiently hard machining high quality internal gears. It combines the flexibility of gear skiving with the advantages of non-dressable CBN tools. An innovative CBN tool by Liebherr-Verzahntechnik GmbH ensures a long tool life and even enables profile modification.
Gear expertise and a customer focus
In November 2024 Liebherr Brasil LTDA held one of its renowned Gear Seminars on gear technology in Guaratinguetá, Brazil. Industry experts were in the spotlight as their presentations focused on grinding, soft machining and measuring technologies. The program provided the wide range of participants with well-grounded technical knowledge and practical know-how, and showcased the expertise and services available at the Brazilian site. The accompanying program offered space for knowledge sharing and direct networking.
Monitoring the energy consumption of machines and workpieces
The new LHEnergyInfo app from Liebherr-Verzahntechnik GmbH measures and displays energy consumption in production in detail and in real time. As an integral part of the LHWebPlatform, it marks another step forward in the company‘s digitalization strategy.
Efficiency gains in twist-free generating grinding
By advancing twist-free generating grinding, Liebherr-Verzahntechnik GmbH is elevating efficiency and quality in hard-fine machining to the next level. The machining times when using dressable grinding worms have been reduced to almost the same level as conventional methods – even with asymmetrical gear teeth. At the same time, optimized shift methods enable fine grinding or polishing to be integrated into a single machining step.
Liebherr apprentices show their commitment to the Allgäu protective forest
Sustainability has long played an important role at Liebherr-Verzahntechnik GmbH – and that is also true for the training program. Since 2011, trainees have been working with the Kempten Office for Food, Agriculture, and Forestry to support the reforestation of the protective forest in the Allgäu region. Head of Training Matthias Fendt and trainees Felix Martin and Lukas Mittermayer report on last year‘s campaign.
Tools for inline process monitoring and condition monitoring
The LHProcessMonitoring software monitors and visualizes the manufacturing process. Initially designed for generating grinding and dressing, it now also supports profile grinding and gear skiving. The “digital fingerprint” for machine monitoring was previously available as part of a maintenance contract. Now customers can perform the measurements themselves using the LHFingerprint software.
From point cloud to picking
In the new version of its bin picking software LHRobotics.Vision, Liebherr-Verzahntechnik GmbH relies on artificial intelligence (AI). By filtering irrelevant image data, it detects disordered workpieces faster and more accurately when removing them from the container.
Precise roughness measurement for internal and external gears
When it comes to aviation, top quality is essential – for every single component. For surface quality measurement, Liebherr-Verzahntechnik GmbH is the only manufacturer to offer a solution for internal and external gears on its measuring devices – optionally with skid or free-moving probe – in a single workpiece clamping.
