The second-generation gear skiving machine is characterized by high rigidity (machine bed, flat guides, spindle rigidity), which means that longer tool holders can also be used. This enables collision-critical internal gears to be produced reliably and in high quality. The tailstock also makes the machine ideal for shaft machining. Chamfering is optimally integrated into the machine with the revised ChamferCut and FlexChamfer units.
Liebherr helps you individually select the gear-cutting tools. Intensive technology development and extensive tests at customers underpin the know-how of our experts. The specific tool development and production are carried out by Liebherr internally. Conical and cylindrical tools can be used.
Highlights
– Fast machining times
– High-performance spindle with internal cooling lubricant feed
– Integrated automation system
– Tool changer integrated in the machine
– Roughing and finishing tools
– Machining cluster gears in one workpiece clamping operation
– Simultaneous gear skiving and chamfering in one machine
– Process-optimized tool design and production
Digitalization Solutions
Customized digitalization solutions for your requirements
With a combination of data profiles, protocols, and the
LHWeb-Platform, Liebherr provides an infrastructure for the
acquisition, transmission, storage, processing, provision, and
display of machine, operating, and production data. In the basic
app LHMachine-Info, users can see the live status of their
machine tools at a glance and observe changes in real-time.
The LHSignalInfo app visualizes the recorded signals, taking into
account all measuring points and their exact time stamp.
The LHReportInfo app visualizes and analyzes the performance
of the machine and generates reports and evaluations from the
machine data—a decisive step toward more productivity.
Gear Cutting Tools
Holistic technological competence with Skiving3
The success of gear skiving lies in the significantly higher efficiency and productivity of this process compared with shaping
and the considerably higher flexibility and lower investment
compared with broaching.
Liebherr knows the entire process of gear skiving profoundly.
We have combined all of our expertise concerning tool design,
machines, and technology of gear skiving in the Skiving3 technology package. Very high accuracy in tool production, coupled with
optimal tool design, guarantees excellent gear quality and long
tool life. Liebherr guarantees the reliability of its manufacturing
process at the highest quality level.
The gear skiving tools are available in tapered and cylindrical form
and can be optionally manufactured from powder-metallurgical
high-speed steel (PM-HSS) or full carbide.
The combination of axial crossing angle, cutting speed, feeding,
and other kinematic parameters make the method very flexible:
Particularly for internal gears in medium batch sizes and external
gears with an interfering contour, gear skiving is an additional
“ace up your sleeve” in the gear cutting range.
Highlights
– Optimal tool design
– Best quality: High level of accuracy and long tool life
– Short delivery times and process support

Measuring Machine WGT 400
Are you looking for a solution to ensure quality and increase
productivity in gear manufacturing?
The four-axis measuring instruments of the WGT series have
high-precision mechanics and electronics, which are controlled by
smart and user-friendly software. They meet all accuracy requirements regarding gear measurement and comply with VDI guideline
VDI/VDE 2613, group 1.
In addition to the gear inspection machine options available as
standard, customer-specific solutions are also available, such as adjusting the travel range on the Z-axis, longer tailstocks to accommodate long shafts, and rotary tables adapted to the payload. An automatic sensor changing system ensures uninterrupted measurement
of the workpieces and also offers the highest levels of convenience
for the user.
The extensive software features make the machines suitable for
measuring all types of gears, such as spur gears, bevel gears,
worms, worm gears, shafts, gear-cutting tools, and other rotationally
symmetrical parts.
Highlights
– Highest precision provided by granite guides and air cushioning
– Low operating costs due to contactless guides and reliable
probes as well as inexpensive spare parts
– Flexible for all types of gears
– User-friendly interface and ergonomic design
– Manufacturer-neutral GDE interface for data transmission
to production machines
– Highest precision provided by the new roughness sensor
PHS Allround Pallet Handling System
Automation system for machine tools from batch size 1
The Liebherr PHS Allround pallet handling system typically interlinks up to four machines and increases productivity—just like all
Liebherr pallet handling systems.
The modular system can be individually configured and expanded
at any time if required. The possibility of the frontal arrangement
of machines, additional units, and shelves offers maximum flexibility in the system design.
Innovative options such as the double loader and front access set
new standards in this product segment. The front access allows
individual machines to be decoupled from the system, while the
remaining machines continue to produce without restriction in
Automatic Mode.
The double loader reduces the time needed for a workpiece
change and thus maximizes its productivity—or it increases its
flexibility by using different pick-up forks for different pallet sizes.
Highlights
– Double loaders as a more cost-effective alternative to machine
trains with pallet changers
– Integration of different machine sizes in one system
– Three sizes for transport loads from 800 to 3,000 kg
– Very narrow telescopic unit combined with large stroke allows
any machine to be loaded
– Can be combined with additional technologies such as
automated setup and tool handling systems for even more
productivity
