Liebherr-Verzahntechnik GmbH presented four machine concepts at EMO 2019. These were characterized above all by their versatility. With technologies such as shaping, worm milling, grinding and skiving, the exhibited products offered a wide range of options for every requirement in gear technology. Here is a review of the trends at the leading trade fair for metal machining.
LS 180 E
The electronic shaping head provides maximum flexibility, allowing the LS 180 E to shape straight and helical gears in one clamping. The easy-to-use control system means that lead modifications with different crowning are no problem. These features make the machine as interesting for the supplier industry as it is for prototype development. Gear shaping is still vital, especially for workpieces without sufficient tool overrun, and will not be replaced by other processes such as the new gear skiving in the future. On the same platform, Liebherr also offers the LS 400 EM, which is ideal for manually loaded workpieces with a diameter of up to 400 millimeters.

LC 80 WD
Thanks to high machine rigidity and fast automation, the LC 80 WD is ideal for milling steering worms and for industrial worm applications. The highly rigid tool and workpiece clamping gives it a long tool life and excellent workpiece quality. It also comes with an optional additional station for a dedicated chamfering or brushing unit. The strength of the machine lies in the quality, cycle time and value-adding additional operations for economical serial worm production.

LGG 180 / 280
In order to avoid waste and make efficient use of resources such as service fluids and expensive grinding coolants, the LGG generating grinding machine has an integrated centrifugal unit. This cleans the gears by throwing off chips and coolant, so that they are transferred from the machining station in a clean condition. The centrifugal unit is decoupled from the machine tool so that no vibrations are transmitted to the process. The direct return of the grinding oil significantly reduces operating costs, and no oil ends up outside the machine. This contributes significantly to sustainable production in a clean factory.

LK 180 / 280 DC
The new-generation LK 180 / 280 comes with a wide range of options: the machine-integrated tool changer with up to twelve storage spaces has room for roughing and finishing tools, but can also be used for other tools, such as for turning, drilling or hobbing. An additional chamfering device with the new FlexChamfer method ensures deburring during the machining process. An integrated tool measuring device for skiving wheels shortens setup times and simplifies operation.
