Hydroviscous damping and changeable bearing preload Beating force} Due to the hydroviscous system, damping of natural vibrations is enhanced considerably. In the axial direction, an improvement in dynamic stiffness of up to 135 % is achieved. This results in significantly reduced natural vibrations in the machining process, enabling a very good surface quality. Under production conditions at GMN’s own manufacturing New spindles are structurally identical to standard models and easy to retrofit in already existing machines facility, GMN grinding spindles have been tested at internal cylindrical...
