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.
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.
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.
Apprentices win VDMA ‘Carbon Busters 2025’ Award
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.
Polishing after shot peening
As power density increases, so do the demands placed on gear teeth – especially in the commercial vehicle sector. Maximum load capacity and service life are achieved through the combination of shot peening followed by polishing of the tooth flanks. The process sequence required for this places high demands on production, for which Liebherr-Verzahntechnik GmbH offers a series ready solution.
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.
Research project on energy-optimized production control
With a new photovoltaic system and the PrONergy research project, Liebherr-Verzahntechnik GmbH is working to intelligently integrate production and energy supply.
As part of the latest machine platform for large gears, the LGP 2000 enables profile grinding across a broad range of applications – from single components to series production. An additional grinding spindle and a double dresser for simultaneous dressing can almost halve machining times.
