  • Investigation of spindle bearing preload on dynamics

    2012-1-1 · In modern spindle designs, the spindle bearing preload can be automatically decreased at higher speeds to reduce heat generation and increase bearing life. This, in turn, can modify the THSM assembly dynamics and, therefore, the process stability. In these instances, the FRF of the THSM obtained from the zero speed preload condition may not be ...

  • Spindle bearing preload selection is key | Cutting Tool ...

    2011-6-1 · Spindle bearing preload is required for static accuracy. It keeps the rolling elements in contact with the spindle and housing and prevents “play” in the spindle. A gap, or play, would allow the spindle to rattle in the housing, and the position of the spindle centerline could shift. In addition to accuracy, preload is required for stiffness.
