Hydrostatic spindle

Hydrostatic spindles or hydrodynamic spindles as tool machine spindles or main spindles have a very good radial accuracy. However, they have disadvantages in terms of rigidity and purchasing costs compared to spindles with roller bearings. With hydrostatic spindles, the shaft is guided by the externally generated static oil pressure in the glide elements provided with oil pockets. Therefore, an additional hydraulic system is required for operation of the hydrostatic spindle. The hydrodynamic spindle is based on the physical principle of fluid friction. Here, friction partner, a separating lubricant film, is generated between the shaft and the glide element under a relative movement.
