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.

Machine table

Dual worm wheel drives or direct drives are used for a backlash-free machine table drive. The table spindle is equipped with hydrostatic radial and axial bearings for high table loads, up to 60/95/120kN and maximum radial rigidity. The water-cooled AC table drive ensures maximum accuracy and reliability. Large table bores accommodate installation of clamping cylinders for workpiece clamping fixtures. In addition, Liebherr also offers the option of a directly driven machine table.

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.

External automation system: ring storage RSP 800

The ring storage offers 8 storage locations for the gear hobbing machines. When all 8 positions are occupied, workpieces with a max. workpiece diameter of 500 mm, a total length of 700 mm and a weight of 500 kg each can be loaded. When 4 places are occupied, workpieces with a max. workpiece diameter of 800 mm, a total length of 700 mm and a weight of 1000 kg each can be loaded.
