Spindle to the aerostatic bearing of a high-speed tool

摘要

Spindle to the aerostatic bearing of a high-speed tool, consisting of a rotating shaft, the aerostatically in at least two bearings in the axial and radial direction, is mounted, wherein the shaft has a freely oscillating extension on the one end of which the tool is attached and the bearing support of this extension of the working tool-side end by a - as a slide or roller bearings is a bearing, which bearing is at least double the bearing play of the radial support aerostatically, characterized in that the two separated and aerostatic bearings are mounted elastically in the spindle housing.
