Abstract:
The invention provides a machine tool capable of facilitating a process of mounting a fluid supplying unit to a spindle supporting unit. The machine tool comprisies a rotating unit including a spindle provided with a workpiece chucking unit, a supporting unit which rotatably supports the spindle around a spindle axis, and a fluid supplying unit removably mounted on the supporting unit to supply fluid to the chucking unit via the spindle. The fluid supplying unit has an insert to be received in the rotating unit in the direction of the spindle axis. A labyrinth clearance is formed between the outer circumferential surface of the insert and the inner circumferential surface of the rotating unit when the fluid supplying unit is mounted on the supporting unit. The labyrinth clearance allows rotation of the rotating unit and restricts leak of fluid from the spindle when the rotating unit is rotated.

Claim (Index 1):
A machine tool comprising:\n a rotating unit including a spindle provided with a chucking unit which releasably chucks a workpiece; a supporting unit which rotatably supports the spindle around an axis of the spindle; and a fluid supplying unit removably mounted on the supporting unit to supply fluid to the chucking unit via the spindle; wherein, the fluid supplying unit has an insert to be received in the rotating unit in the direction of the axis of the spindle, wherein the rotating unit has an inner circumferential surface opposite an outer circumferential surface of the insert received in the rotating unit, and wherein a labyrinth clearance is formed between the outer circumferential surface of the insert and the inner circumferential surface of the rotating unit when the fluid supplying unit is mounted on the supporting unit, the labyrinth clearance allowing rotation of the rotating unit and restricting leak of fluid from the spindle when the rotating unit is rotated.
