Is performance-related gear cutting possible on your machine? As nowadays the need to be economical is more important than ever, modern machines are required.
The Liebherr LC series ensures reliable machining with the required torques and cutting forces. This allows us to reinforce the capability of modern CNC gear hobbing machines.
The machine concept fulfills quality requirements such as accuracy, stability and temperature resistance. Stable processes are realized during pre- and finish cutting.
Is dry gear hobbing for large modules (m>10) possible? Yes, as you can see in the picture on the left.
Flexible layouts possible
Chip conveyor can be retracted if required (shaft machining)
Temperature stable, as there is no direct connection between machine table, machine bed and counter column. The connection is made via the foundation.
Welded machine bed for higher rigidity
Hardened guideways
Use of flat guides for increased damping and reduction of vibrations
X1 - Radial movement column slide | V1 - Tangential movement tool | Z1 - Axial travel tool | B1 - Rotary movement tool | C2 - Rotary movement workpiece | A1 - Swivel movement tool | Z4 - Vertical travel tailstock
With the LC 4000, Liebherr is breaking new ground in the production of large gears and combining different hobbing methods on a highly efficient machine for the American gear specialist.
The machine has a new type of direct-drive cutter head as well as an additional finger milling head for external and internal gears with its own main column.
