Abstract
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.
Claims21
A tool head for a machine tool, comprising:
- a first spindle unit with a first spindle shaft which is mounted in the first spindle unit so as to be rotatable about a tool spindle axis;
- a first balancing device associated with the first spindle unit;
- a second spindle unit with a second spindle shaft which is mounted in the second spindle unit so as to be rotatable about the tool spindle axis;
- and
- a second balancing device associated with the second spindle unit,
- wherein the first spindle unit and the second spindle unit are arranged coaxially with respect to each other in such a way that a tool is receivable axially between the first spindle shaft and the second spindle shaft, and
- wherein at least one of the first balancing device and the second balancing device radially surrounds the spindle shaft of its associated spindle unit and is arranged axially between a tool-side spindle bearing of its associated spindle unit and a tool-side end of said spindle shaft.
A tool head for a machine tool, comprising:
- a first spindle unit having a first spindle shaft mounted in the first spindle unit so as to be rotatable about a tool spindle axis;
- and
- a second spindle unit with a second spindle shaft which is mounted in the second spindle unit so as to be rotatable about the tool spindle axis,
- wherein the first spindle unit and the second spindle unit are arranged such that a tool is axially receivable between the first spindle shaft and the second spindle shaft,
- wherein
- the second spindle shaft has at least one axial bore,
- wherein the tool head comprises at least one pull rod extending through the axial bore of the second spindle shaft, the pull rod being connectable at a first end to the first spindle shaft, and
- wherein the pull rod can be connected at a second end to the second spindle shaft in such a way that an axial compression force can be generated on the tool between the first spindle shaft and the second spindle shaft.
