Machine Concept Liebherr hobbing machines are optimized for universal gear applications. Our high-performance hobbing machines are productive and machine in the highest quality. • Optimised stiffness of the machine bed with FE Analysis model • Thermo-symmetrical machine design for constant high quality • Safe and problem-free removal of chips • High flexibility for different processes: - Gears, shafts, worm gears - Cluster gearing - Skiving - Positioned/Oriented gear teeth • Wet and dry processing • Hook-ready machine with compact floor space suitable for straightforward implementation Steady...

Direct Machine table A workpiece drive with absolutely zero backlash is needed for machining gears. The table drive with pre-loaded helical gears and zero backlash is available when using conventional technology. For high performance cutting (HPC) there is an ultra-dynamic direct drive available which satisfies all requirements with respect to speed and precision. Direct Hob head The tool spindle is directly driven by a maintenance-free AC motor. High drive power up to 23 kW and speeds up to 6,000 rpm give ample reserve for future tool developments. When torque demands are particularly high,...

Chamfer/Deburring in the working area Rough deburring Rough deburring can be integrated into the working area and is simultaneously performed. ChamferCut The established ChamferCut process offers many benefits: • High chamfer quality and precise chamfer geometry • No tooth-flank bulging or material deformation • Very long tool life (also with dry cutting) • No needle chips • ChamferCut is easy to sharpen • Economical production solution for chamfer/deburring Simultaneous chamfer/deburring in a second machining position Roll-press Chamfer/Deburring Roll-press device for chamfering the tooth edges...

Software/control technology The new, user-friendly LHGe@rTec® interface makes it much easier to operate the gear cutting machine and has many advantages for the operator: • Individual configuration • Intuitive operation • User guidance for process and change-over procedures • Mathematical analysis • Touch screen • Graphical input support • Incorporation of additional documentation (e.g. fixture layout, hob tool/arbor assembly, etc.) • Integrated webcam • Siemens 840 D Solutionline The Collision Control software package is available to minimise damage in the event of unexpected impact between tool...

Palletizing Cell (LPC) Standardized transport containers with basket technology facilitate a uniform approach to logistics, as well as flexible future-oriented production. 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. Robot Cell (LRC) Hook-ready robot solution in modular design replaces complex sorting systems, increases...
