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.

With the newly formed “Industrial Services” department, Liebherr-Verzahntechnik GmbH is reimagining the service ethos.

After an upgrade, the universal LC 280 DC gear hobbing machine shines with improved operating comfort and technical refinements.

It begins with an idea. But designers often have a long way to go before a perfect workpiece is made using a suitable manufacturing process. It is good that reliable partners such as Liebherr participate and share their experiences.

Simply order from the catalogue and two days later the new shaping tool will arrive: Liebherr makes the process as straightforward as this for customers and offers a broad range of stock tools available for immediate delivery. New: Instead of cutting material ASP2030 with a titanium nitride (TIN) coating, stock tools are now made as standard from ASP2052 with Alcrona Pro.

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.

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

While we still have some way to go to achieve autonomous driving on the road, factories are miles ahead: AGVs (automatic guided vehicles) are already being used in the area of production.

The constantly rising demands from the markets, such as higher accuracy, more effective processes and increased flexibility, require sophisticated machine concepts. For this reason, the new gear skiving machine generation has been equipped among other things with a tool changing system integrated in the machine, multi-machining functions, an integrated measurement device for tools and the option of chamfering during the machining process.
