Liebherr will feature its LK 300 and 500 gear skiving machines, which are based on components of corresponding large hobbing machines. These machines are rigid and equipped with powerful spindles and direct-drive tables to handle high workpiece speeds. The drive works with an automatic control which is said to maintain optimal parameters. The machines are supplied on a turnkey basis with individual clamping fixtures for each workpiece. A ring loader is the machine’s standard workpiece changing device. The LHGearTec control system contains mathematical formulas for pressure and angle corrections said to improve quality via the machine’s kinematics. Automation options include a toolchanger, belts and robots.
