The new high speed spindles successfully reduces natural vibrations by up to 65 % in comparison with standard spindles. This makes for more cost-effective workpiece machining, since components can be worked consistently with greater cutting depths and therefore higher material-removal rates. Improved surface quality is obtained at all speeds – not only for rough-machining, but also during the finishing process and grinding.
The new spindles are characterised by a vastly improved dynamic stiffness. Thanks to the hydroviscous system, damping of natural vibrations is enhanced considerably. In the axial direction, it was possible to achieve an improvement in dynamic stiffness, for example, of up to 135 %. This results in significantly reduced natural vibrations in the machining process, enablin...
