Liebherr – Gear Skiving – LK Series
The foundation is the rigidity by the machine: The cast iron machine bed absorbs resulting process forces. The use of flat guides in all important linear axes provides additional damping. A high spindle rigidity is attained in the machining head using a special bearing concept, in which longer tool holders can be used – this is particularly important for machining internal gears.
In addition to the machine, the appropriate tool is crucial for a stable process. With its in-house tool development and manufacturing, Liebherr can design the optimal tool for every workpiece.
The planned process must be taken into account when designing tools. Thanks to intensive technological development and extensive tests with customers, Liebherr understands the interaction between machine and tool and is in a position to be able to offer a skiving machine, tools, and to provide the Skiving³ process.
