A team of four apprentices from Liebherr-Verzahntechnik GmbH has won the VDMA ‘Carbon Busters 2025’ award with an innovative concept for reducing emissions. Their idea was an energy self sufficient training center.
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.
Bin picking and gear hobbing technology in the production of geared shafts at Rickmeier
From unsorted raw parts to geared pump shafts: with a highly automated production line, Liebherr-Verzahntechnik GmbH has implemented an end-to-end process chain for the pump manufacturer Rickmeier GmbH in Balve.

Flexible chamfering with new functions
Liebherr-Verzahntechnik GmbH has further developed the FlexChamfer chamfering process specifically for greater user benefit, ease of use and flexibility. New software functions enable even complex chamfers to be calculated independently. A new interface allows switching between FlexChamfer and ChamferCut on one machine for the first time. Additional functions improve safety and efficiency in operation.
Liebherr strengthens its presence with customers in Japan
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.
Gear technology and automation move closer together
The Tech Center and the Machine Training Center (MTC) of Liebherr-Verzahntechnik GmbH have moved to new premises near the main plant in Kempten. The new site brings automation development and testing together with gear technology training under one roof, creating close links between automation, gear technology and production.
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.
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.
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.
