Abstract
A spindlehead for tools is insertable into a tool disk with holders provided for such spindleheads. A spindle holds the shank of the tool in its chuck at its front end section, and is rotatably mounted by a spindle bearing in a spindlehead housing. A coolant feed extends at least in part in the spindlehead housing to convey coolant to the tool via at least one coolant channel and an internal coolant feed line in the spindle. A sealing device with a throttling point is separated form parts of a drainage channel. The sealing device has at least one sealing ring enclosing the spindle. The sealing ring is longitudinally movable in the spindlehead housing coaxially with the spindle axis. After longitudinal movement into a sealing position, the sealing ring separates the internal coolant feed line from the associated parts of the drainage channel up to a specifiable leakage amount. The accuracy of machining with the tool may be increased and the installation space available can be better used.
