  • Half a century of Liebherr-Verzahntechnik GmbH means 50 years of commitment to the machinery and plant engineering industry. Gear technology originated in the technology of the revolving tower crane. Hans Liebherr wanted to buy a gear hobbing machine for gear manufacturing, but could not find what he wanted – so he simply built it himself. It’s a typical Liebherr story, since many sectors in the company group have emerged in this or in a similar way. Taking things into one’s own hands: an attitude that can still be found at Liebherr today.

  • Bauer Gear Motor operates two new LC 180 gear hobbing machines at its facility in Slovakia, producing gearing for all facilities. These machines are characterised by their operational versatility, given that they are used to produce around 180 different components in a very wide range of different sizes.

  • “The fire pump is the heart of every fire truck”, explains Michael Schöftner, Head of Mechanical Production at Rosenbauer International AG, the global leader for fire service equipment. The equipment has to withstand enormous loads in cases of operation. Rosenbauer relies on an automation solution for pump manufacturing from Liebherr. The rotary loading system RLS 800 from the Kempten-based automation experts has been deployed in Leonding near Linz for around two years now.

For long shafts: LGG 400 M

Based on the proven LGG 280 generating grinding machine, Liebherr is presenting the larger LGG 400 M model at IMTS in Chicago.

LHGearTec

When Peter Pruschek, Head of Electronic and Control System Development at Liebherr-Verzahntechnik GmbH, presents the new LHGearTec control system, he first highlights the striking new features: “We are entering the market with a 24 inch touchscreen monitor – an above-average size for machine tools.

ChamferCut: Chamfering despite interference contours

As before, ChamferCut is a technology with a great deal of development potential. A new upgrade is now pushing the limits of the impossible.

Passion for Pumps

Integration of measurement technology

Wenzel GearTec GmbH, a successful manufacturer of gear inspection machines, has been part of Liebherr-Verzahntechnik GmbH since May 2019. The Karlsruhe-based company has specialised in the measurement of gears, gear cutting tools and other rotationally symmetrical workpieces since 2004 and has an innovative product range that perfectly complements Liebherr's own.

Future challenge: modernisation of trade training for industrial mechanics

What challenges does Industry 4.0 present to companies and their apprentices? Liebherr is already working on the measures necessary for overcoming the technical obstacles of the future in order to train its own professionals.

Robot systems: workpiece handling with vision

It starts with a blank. But how does the workpiece get onto the line or into the machine? Depending on the state it is delivered in, this task can quickly become very complex. Reliable 3D object detection systems optically capture and evaluate data. Liebherr works with a variety of 3D vision systems to match the requirements and smoothly handles the supply of every randomly stored part with process precision.

CBN generating grinding - a thoroughly economic alternative

The demand for high quality gear teeth in areas such as electric mobility, for example, come with great challenges. Liebherr is working on the development of solutions for economic manufacturing
