ABSTRACT:
A spindle head for tools with interior coolant feed can be inserted in a tool face with receiving and holding bores. A tensioning device for the spindle carries the shaft of the tool and is mounted rotatably in the spindle head housing by a spindle end segment. A coolant conduit is located in a spindle head cover on the tool side and above the spindle mounting. An annular groove open toward the spindle end segment is provided in the spindle head cover. A coolant feed passage opens into the annular groove. The end segment of the spindle has a connecting passage with one end opening in the annular zone of the outer surface of the end segment aligned with the annular groove and with another end opening in a chamber of the spindle. An inlet opening of the coolant passage in the shaft end of the tool is connected with the chamber. The annular groove is sealed on the outside by an exterior gap tightening and on the inside from the spindle mounting by an interior gap tightening. Both the exterior and interior gap tightenings are limited by the outside surface of the spindle and the inside surface of the spindle head cover.
