摘要： A hub flange has a fixed flange configured to receive a tool body. A flange socket is formed on the fixed flange for connection to a spindle shaft. A counterflange is detachably connected to the fixed flange. The fixed flange and the counterflange are connected to each other via a conical connection, wherein the conical connection is arranged coaxially to the tool axis and is formed by an inner cone and an outer cone received therein.

摘要： A tool head for a machine tool, in particular for a gear cutting machine, has a first and a second spindle unit each having at least one spindle bearing and a spindle shaft which is rotatably mounted in the respective spindle bearing about a tool spindle axis. The respective spindle bearing can support both radial and axial forces. The spindle units are arranged coaxially to each other, and a tool is received axially between the spindle shafts. A controlled clamping device connects the spindle bearings together. A control device activates the clamping device during a machining operation and deactivates it during machining pauses. Alternatively or additionally, the tool head has an axial force element that generates an axial preload force between the spindle bearings.

摘要： A tool head for a gear cutting machine includes a first spindle unit having a first spindle shaft and a second spindle unit having a second spindle shaft. A tool is axially receivable between the first spindle shaft and the second spindle shaft. A balancing device is associated with each spindle unit. The balancing device radially surrounds the respective spindle shaft and is axially arranged between a tool-side spindle bearing of the corresponding spindle unit and the tool-side end of the corresponding spindle shaft. The tool is axially clamped between the two spindle shafts by a pull rod and a clamping element.
