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 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).
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.
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.
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.
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.
CHIRON Group relies on LHRobotics.Vision smart technology package
The CHIRON Group, headquartered in Tuttlingen (Germany), is a leading global specialist in CNC-controlled machining centers as well as turnkey and automation solutions. To make its advanced automation projects more flexible and efficient, the company sought a bin picking solution independent of specific robots and cameras – and found the ideal technology package in LHRobotics.Vision from Liebherr-Verzahntechnik GmbH.
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.
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.
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.
