The Gear Seminars held by Liebherr-Verzahntechnik GmbH in Japan have become an important meeting point for the country’s gear manufacturing industry. More than 100 participants attended the events in Tokyo and Osaka in November 2025 to learn about innovations and new technologies, share insights and gather fresh ideas for their own production operations.
Small batch sizes and a wide range of gear types: Terhaerst Maschinenfabrik GmbH in Neunkirchen near Nuremberg has invested in an LC 700 M gear hobbing machine from Liebherr-Verzahntechnik GmbH. The new machine replaces several older units and allows the company to manufacture a broad spectrum of workpieces with significantly shorter processing times.
At Liebherr-Verzahntechnik GmbH, apprentices from multiple disciplines jointly designed and built an interactive exhibit for events and training fairs – based on a classic arcade grabber machine.
Gear cutting machines generate vast amounts of valuable data, which can provide users with a key to better process understanding, higher quality and targeted optimization. In practice, however, these potentials often remain untapped: Data is scattered, difficult to access and often not linked in a meaningful way. The Liebherr Data Suite combines a range of integrated software tools into a comprehensive system designed for targeted data usage.
The line runs from bin picking at the start, through several machining stations including gear hobbing, all the way to automatic unloading of finished parts. The result is higher productivity, stable processes, and maximum flexibility.
SkiveFinishing® for industrial applications
With SkiveFinishing®, Liebherr has developed a process that sets new standards in the hard finishing of internal gears. Following successful proof of technological feasibility, the focus is now firmly on industrial deployment. The aim is to develop a robust, cost-efficient manufacturing process that combines the highest quality standards with maximum productivity.
Arcade attraction as an interdisciplinary training project
At Liebherr-Verzahntechnik GmbH, apprentices from multiple disciplines jointly designed and built an interactive exhibit for events and training fairs – based on a classic arcade grabber machine.
Consistently recording, storing and analyzing machine data

A modern machine concept for efficient rotor machining
Rotors are used in a wide range of applications – and their importance is growing. At the same time, they are demanding components that require the utmost stability and precision. In the past, they had to be made using special equipment, but now they can also be produced on standard hobbing machines such as the LC 500.
Advancements in waviness analysis
Liebherr-Verzahntechnik GmbH continues to advance waviness analysis in gear metrology, with a focus on powerful evaluation capabilities and ease of use.
More than just a technology supplier: Liebherr-Verzahntechnik GmbH
The robotics market is developing rapidly – but it is currently difficult to predict with any certainty exactly where it is heading. Liebherr-Verzahntechnik GmbH has gained expertise and experience from numerous completed projects involving various robotic drive systems. Dr Oliver Winkel, Head of Application Engineering, speaks with product managers Martin Schwarzmann and Laurenz Müller about what makes the company a strong development partner for the robotics industry.
Pallet handling for heavy parts in small batch sizes increases productivity at Köppern
Manufacturing of extremely heavy individual parts in small batch sizes is beyond the limits of traditional automation. Hattingen-based company Köppern, which specializes in high-pressure roller presses, restructured its production process to include two Liebherr pallet handling systems, shortened processing times, and significantly increased machine utilization.
LHProcessMonitoring software with high-frequency sensor system
Unwanted noises in the drivetrain are often caused during the manufacturing process: In e-mobility in particular, the smallest errors on the gear surface have a significant impact on subsequent NVH (noise, vibration, harshness) characteristics. A new high-frequency sensor system, LHProcessMonitoring, enables even finer measurements and detects even the smallest process deviations at an early stage.
