Liebherr Brasil Ltda is celebrating its 50th anniversary in 2024. Excavators, cranes, truck mixers and slewing bearings are just some of the products manufactured for the South American market at the site in Guaratinguetá, Brazil. The sales and service activities of the group are also gathered together here. Liebherr-Verzahntechnik GmbH also has 15 employees at the site.

The Liebherr WGT series of gear measuring machines are used in gear manufacturing for a wide range of industries: from the smallest aerospace applications to large gearbox components for wind turbines, tower cranes or commercial vehicles, where some of the gears weigh tons. With the optimized WGT 1200, Liebherr-Verzahntechnik GmbH provides high-precision measurement even for huge workpieces up to a diameter of 1400 mm and a weight of 5 tons.

For the manufacturing of valves and valve kits, Linde Hydraulics GmbH & Co. KG invested in a production plant at the Ballenstedt site with five 5-axis machining centers from Grob, which are interlinked via the PHS 1500 Allround pallet handling system from Liebherr-Verzahntechnik GmbH. This enabled the company to increase the output of this manufacturing line by 30%. The planning was quite a challenge: due to the high demand, not only did additional machines have to be integrated, but an alternative location for the plant in the historic production halls also had to be found during the project.

Gear skiving used to be a gear cutting method that was difficult to control due to its complex kinematics, but it now offers a genuine alternative to shaping or broaching. The synergy between machines, tools and processes provided by Liebherr-Verzahntechnik GmbH’s Skiving³ technology package makes it possible to efficiently and flexibly machine an extremely wide variety of workpieces, including in small batch sizes. Skiving³ therefore crucially boosts productivity, quality and cost-effectiveness levels not just in series production, but in contract gear manufacturing as well.

With the PHS 10000 Pro pallet handling system from Liebherr-Verzahntechnik GmbH, the machine tool manufacturer GROB in Mindelheim has automated its in-house production of machine components on two 4-axis machining centers and thus increased productivity by around 45%. The challenge here was not only to manage large parts weighing tons, but also a series of additional constraints that required highly individual solutions, as well as project planning where not a single day‘s work could be delayed.

Pongi Gear Experts Co., Ltd. has represented Liebherr-Verzahntechnik GmbH in Taiwan for many years. In 2022, it incorporated the Kempten company‘s bin picking software into its portfolio and set up its own demonstration and training facility for intelligent automation. Potential customers can evaluate the smart and intuitive system on a fully equipped cell with a camera, robot and simulation tool.

Julia Stachel and Laura Scheiber completed their training as industrial mechanics at Liebherr-Verzahntechnik GmbH at the beginning of 2024. During their training period, they spent four weeks at the Liebherr plant in Yongchuan, China in August 2023. Here they explain what made them choose China, their experience there and what it is like to suddenly have lots of people wanting to take a photo with you!

Liebherr-Verzahntechnik GmbH is taking the plunge into artificial intelligence (AI) with its latest version of LHRobotics.Vision bin picking software. Filtering out irrelevant image data enables faster and more accurate detection of unsorted workpieces when removing them from containers.
