Machine design

Our Liebherr gear shaping machines are optimally adapted to the diverse requirements of universal applications. Their axially movable shaping head slide enables extremely efficient production of very diverse components with minimum setup time. The variable machining position enables optimum alignment of the shaping head depending on the clamping fixture used. Thanks to the variable machining positions, multiple gearings can be machined within a single clamping fixture.

Our machine concept is suitable for wet machining as well as dry machining.

For economical and efficient production, we recommend the ringloader concept, which enables fast loading and unloading of workpieces. In addition, Liebherr offers various external automation systems such as a plastic chain conveyor and chain conveyor storage mounted directly on the machine.

Automation & features

Plastic chain conveyor (KKB)

The plastic chain conveyor is available in the standard version for workpieces up to 20 kg in weight and in the heavy duty version for workpieces up to 180 kg in weight, and is designed to transport any number of irregularly shaped workpieces without them coming into contact with each other. The workpieces are transported on pallets. The queue effect means that they are cycle-independent.

Chain conveyor storage (KSR)

The small, compact KSR chain conveyor storage enables storage and transportation of workpieces up to 180 mm in diameter and 300 mm in length. The maximum total load is 75 kg. This compact workpiece storage unit can also serve as an additional buffer option, for example with a robotic workpiece feed.

Easy to maintain

Optimum machine accessibility during maintenance work is a prerequisite for ensuring productivity. For this purpose, all necessary maintenance access points are equipped with doors. Moreover, to enable quick and easy additional monitoring of specific statuses, window panes are inserted into the maintenance doors. This means the machine operator or maintenance personnel can read the signals from outside in very little time. An enclosure for the hydraulics has also been integrated into the new machine design. This ensures sustainable reductions to hydraulic power unit noise.

Software/control technology

The new, user-friendly LHGearTec user interface makes it much easier to operate the gear cutting machine and has many advantages for the operator.
