The Machine Concept In gear manufacturing, the technology of high-speed dry hobbing has substantially reduced cutting times and machining costs while increasing workpiece quality and environmental protection. Originally introduced by Liebherr, this process has met with tremendous success. The new demands of this modern technology include higher hob and table speeds, reliable removal of the hot chips, and machine-wide management of the considerable process heat. The proven machine concept also offers a number of significant new developments: the completely symmetrical design of the machine’s...

The Machine Bed The rigidity of the machine structure was optimized using FEA simulation. Steep side walls and two integrated chip augers offer efficient and reliable chip removal. This is especially important for dry cutting. The Hob Head A maintenance free direct drive AC motor is used for the hob spindle. Drive power up to 27 kW and speeds up to 3000 rpm offer large reserve capacity for future tool developments. For very high torque requirements the hob head is equipped with a reduction gear drive. The tool interface is offered either with a hollow shaft taper (HSK), a collet or a steep...
