Product catalog summary

Machine Concept
The LC 600 – 2000 series from Liebherr is designed with flexibility in mind, featuring a two-piece machine bed that allows for optimal configuration to meet customer-specific requirements. The machines are self-supporting and can be installed directly on the floor without a special foundation. Chip removal is efficiently managed through the machine bed, and the coolant system holds approximately 800 liters.

Hob Head
The hob head utilizes maintenance-free, high-dynamic AC drive technology, providing the necessary torque for high-performance cutting at spindle speeds up to 1000 rpm and 45 kW. It supports both HSK and ISO taper mountings, with an optional internal hob head for single indexing internal machining.

Machine Table
The machine table features dual worm wheel or direct drives for backlash-free operation, with hydrostatic bearings supporting high table loads up to 120 kN. The water-cooled AC table drive ensures accuracy and reliability, and large table bores accommodate hydraulic clamping cylinders.

CNC Control
Liebherr hobbing machines are equipped with reliable and maintainable control technology, featuring Siemens control systems with digital drive technology, integrated PLC, and advanced field bus systems. The machines offer optional network integration and diagnostic tools.

Automation
Workpieces up to 800 mm in diameter can be automatically loaded and unloaded using a 2-station ringloader with adjustable parallel grippers.

Technical Data
The series includes models LC 600 to LC 2000, with maximum workpiece diameters ranging from 600 mm to 2000 mm. The machines offer various specifications for hob slide travel, table diameter, and drive power, tailored to different manufacturing needs.
