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.
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.
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).

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.
Market and product distribution in Mexico
In April 2024, Liebherr-Verzahntechnik GmbH opened a branch in Mexico. The Querétaro site specializes in the sale and servicing of gear cutting machines and tools, measuring technology, and automation systems. Branch Manager Miguel Cisneros serves customers nationwide. He is supported in this role by Felix Scholz, General Manager of Liebherr Gear and Automation Technologies, Inc. in Saline, Michigan (USA), and Andreas Heider, Sales Director Gear Cutting Machines in Kempten (Germany). In the interview, they discuss goals, collaboration, and market potential.
Liebherr systems expand complex manufacturing at Airbus Aerostructures GmbH
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.
Rooted in all company departments
Sustainability at Liebherr-Verzahntechnik GmbH is firmly rooted in all processes. Policies to conserve resources, increase energy efficiency and boost the circular economy are interconnected and incorporated directly into the products.
Interdisciplinary training project in automation
As part of an interdisciplinary training project, apprentices at Liebherr- Verzahntechnik GmbH have single-handedly designed, built and programmed a small-scale gantry loader. The aim of the task was to create a functional model, which replicated real processes in automation systems and could also be used as a practical learning object and for demonstrations. This was largely achieved by a project team of apprentices and dual-program students working autonomously.
Bundled machine portfolio for maximized customer benefits
Liebherr-Verzahntechnik GmbH is restructuring its gear cutting machine portfolio along two lines: Series machines for economical, fast solutions with proven technology – and regulation machines for individual requirements. Both approaches share a common goal: to maximize customer benefit while maintaining consistently high quality.
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.
