Gear Production and Automation Solutions by Liebherr

Single Table Gear Grinding Solution

With a one-table design and a new-design grinding head, the Liebherr LGG 180 and LGG 280 machines greatly reduce grinding times for twist-free profile and generating grinding.

Ideal for consistent high large-scale production quality in automotive applications, including conical gearing, these space-saving machines can be arranged to provide a complete production line for grinding all gearing components for an automotive transmission: planetary and sun gears, bore-type gears, as well as drive and pinion shafts with lengths up to 500 mm.

The advantage to the one-table solution: higher quality throughout the entire production. There is one clamping fixture, one geometry, so each part is machined under the same conditions for the highest reproducibility. The one-table approach provides the statistical capability and reliability in continuously producing controlled µ-range finish quality for gear noise optimization.
