SkiveFinishing® – precision meets efficiency
SkiveFinishing® is an innovative hard finishing process for internal gears that combines the strengths of two proven technologies. SkiveFinishing® merges the flexibility of gear skiving with the advantages of CBN tools that do not need dressing. Optimal surface finishes and highly efficient processes can be achieved by selecting specific CBN grain sizes. Developed by Liebherr-Verzahntechnik GmbH, it fills the gap between fast but less precise hard skiving and highly precise but cost-intensive profile grinding. A newly developed CBN-coated tool with multiple shift positions ensures exceptional process stability, extended tool life and the ability to correct profiles. This makes SkiveFinishing® ideal for industries with demanding quality requirements and strong cost pressures – such as aerospace, e-mobility, and commercial vehicles.

LGG 300/380/500 generating gear grinding machine
The LGG series combines the three technologies of generating, profile and internal grinding in one machine. Thanks to this technological diversity, Liebherr offers the universal user maximum benefit and a secure investment for the future. The machine can be configured for the individual application. This can be done, for example, by an external automation system using a plastic chain conveyor or robot automation. The LGG is also the most powerful generating gear grinding machine in its class on the market. With the GH 320 CB gear skiving head, workpieces up to module 14 mm can be very economically machined to excellent quality. The extended travel ranges allow the machining of long shafts and at the same time improve the internal grinding of deep workpieces.
DIP – Dresser independent profile modifications
DIP is a versatile generating grinding method specially developed by Liebherr that uses dressable grinding worms. It allows profile modification on the workpiece when using profile rolls in the dressing process. In particular, profile angle modifications, crowning, as well as tip and root reliefs can be precisely specified and ground. It offers the advantage that using profile rolls makes the dressing process many times faster, and the surface of the worm is the same as for typical series production.
LHProcessMonitoring
Inline process monitoring with LHProcessMonitoring
The LHProcessMonitoring software from Liebherr-Verzahntechnik GmbH for inline process monitoring visualises the production process and uses the training data to determine limit values for monitoring the production process. This way, deviations that could lead to noise abnormalities can be identified. The software is optionally available as part of the LHGearTec operating and programming interface, making it a consistent continuation and expansion of our digitalisation product portfolio.
With continuous recording and transparent evaluation, the software enables the operator to optimise and stabilise the manufacturing process. Limit violations are automatically detected to prevent the affected components from entering the subsequent process. LHProcessMonitoring ensures the consistent quality of every individual gear and can be used instead of full downstream testing with a single flank check system or master gear, thus saving investment and set-up costs for comparatively little outlay.
