Abstract
A tool carrier for lathes, in particular a tool turret, having a plurality of stations for holding tools, at least one of which is provided with a driven tool spindle designed as a hollow shaft and rotatably mounted in a housing. This tool spindle accommodates a tool chuck which is coaxial to and non-rotatably connected with the tool spindle and is displaceable in axial direction relative to the tool spindle for opening and closing. The tool carrier also has a threaded spindle connected in axial direction with the chuck and a nut arranged thereon for opening and closing the chuck. To simplify the construction only one drive shaft is provided and this shaft is constantly coupled with the nut and connected with the tool spindle via a releasable coupling.
