Machine concept

For the development of this machine series, the characteristics of the very successful new machine generation from Liebherr was systematically transferred to the application of the universal machines LC 600 LC 2000.

The necessary flexibility for different applications is achieved with a two-piece machine bed. With this concept, the machines can be optimally configured to customer-specific requirements. The self-supporting, very rigid design allows a machine installation directly on the floor, without a special foundation.

Chip removal is accomplished through the machine bed with the chip conveyor arranged lengthwise. The machine bed and the laterally arranged coolant lubricant tanks hold approx. 800l of coolant.

Cutter head HH 300

Maintenance-free, high-dynamic AC drive technology with different transmission ratios for the backlash-free tool drive provide the torque required for high performance cutting, at spindle speeds up to 1000 rpm and up to 53kW. The tool holder is realized with the ISO steep taper. An index milling head is available as an option as quick change unit for single internal machining of internal gears.

Internal ringloader automation

Workpieces up to 800 mm diameter and max. weight of 1000 kg can be loaded and unloaded automatically with a 2-station NC ringloader. Use of proven Liebherr parallel grippers with adjustable diameter range are recommended for a large part variety.

Highlights of the Liebherr LC 600 - 2000 gear hobbing machine

The LC 600 - 2000 is specifically designed for the machining of large-modulus gears and shafts as well as internal gears. All models in this series are based on modular components with different tables, heads and counter column assemblies.
