Precision Gear Grinding of Long Shafts

Ideal for aerospace suppliers and job shops, the travel of the main and counter column in the compact LGG 400 M gear grinding machine from Liebherr has been extended for precision machining of long shafts.

Users of the flexible LGG 400 gear grinding machine from Liebherr can utilize a variety of grinding heads for internal and external gears, performing high productivity generating grinding on workpieces up to 280 mm diameter or profile grinding on even larger components up to 400 mm. Fold-out stair steps provide them with better reach into the working area, with large viewing windows of the work envelope and the process. (first view)

The new LGG 400 M gear grinding machine from Liebherr Gear Technology Inc. (Saline, MI) is developed with an eye towards aerospace and job shops. It fits into the same footprint as the smaller LGG 280 system, but is well-suited to machining long shafts because the travel of the main and counter column has been extended. “Users can utilize a variety of grinding heads for internal and external gears,” explained Oliver Kraft, the manager of development and design of gear cutting machines at Liebherr-Verzahntechnik GmbH (Kempten, Germany). “They can perform generating grinding with high productivity on workpieces up to 280 mm diameter or profile grinding on even larger components up to 400 mm. This means even greater flexibility than its sister machine.” Long shafts with small diameters have come into demand, required by the aerospace and job shop industries, often for short runs. An optional crane for optimal handling of large parts is also offered. “We have ergonomically adapted the machines overall,” added Kraft. “Due to the height, we have incorporated fold-out stair steps so workers are better able to reach the working area. Large viewing windows provide the operator with the best possible overview of the work envelope and the process.”
