Arrangement for delivering coolant fluid to the rotating part (1,3) of a tool spindle intended to support a tool at one end. It is distinguished in that the end of the rotating part (1,3) that is opposite the tool is accommodated in a unit (4) that is stationary in relation to the rotating part (1,3), that the rotating part has an axial bore (6) of the rotating part (1,3), that a gap sealing separates the rotating part (1,3) from the stationary unit (4) adjacent to the inlet thereby forming a dynamic bearing during the rotation of the rotating part due to leakage of the coolant fluid through the gap sealing. |
