CNC gear-hobbing machine L series

The high-performance LC 600 - 2000 gear hobbing machines feature a high degree of flexibility in the gear cutting of cylindrical gears and shafts. The modular machine concept takes into account the diverse requirements of different industries. 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.
