High speed spindle, has spindle shaft, which has axial through-hole through which tool holder shaft passes and tool holder shaft is coupled with spindle shaft torque-proof but axially displayable relative to tool holder shaft
High speed spindle, has spindle shaft, which has axial through-hole through which tool holder shaft passes and tool holder shaft is coupled with spindle shaft torque-proof but axially displayable relative to tool holder shaft
The high speed spindle has a spindle housing (1), a spindle shaft (3) pivot-mounted in the spindle housing by using hydrostatic bearing at a rotary axis (X), and a tool holder (4) coupled with the spindle shaft . The spindle shaft has an axial through-hole (31) through which a tool holder shaft (48) passes. The tool holder shaft is coupled with the spindle shaft torque-proof but axially displayable relative to the tool holder shaft. The translation impulse (6), affecting the tool holder shaft, is provided for axial shifting of the tool holder shaft and the tool holder.
