Features

With the new Kellenberger 1000, Kellenberger has been making success a continuous story. The new Kellenberger 1000 integrates functional design and high-precision technology. Hydrostatic guides ensure maximum dimensional accuracy in grinding tasks with interpolating axes.

High positioning accuracies and speeds are ensured by direct drives for the rotary axes. Generous X and Z axes strokes together with the platform concept for grinding head positions and dressing systems assure flexibility and enable application-specific configurations.

The established integral transportation concept (hook machine) has been retained and decreases machine commissioning times while ensuring a small installation area. Energy-efficient concepts and durable hydrostatic guides ensure a highly secure capital investment.
