Abstract
A spindle/tool combination for a machine tool is provided, including a tool, a spindle, on which the tool can be releasably fixed and by means of which the tool can be rotated, wherein the tool has at least one linearly movable rod and the spindle comprises a loading device, which acts on the at least one linearly movable rod of the tool, and a pull/push coupling device, by means of which the at least one rod of the tool can be coupled to the loading device, the at least one rod being actuable by means of the loading device by pushing and pulling when coupled, wherein the pull/push coupling device comprises a clamping jaw and the clamping jaw is arranged in the tool.

A spindle/tool combination for a machine tool, comprising:
- a tool;
- a spindle, to which the tool is releasably fixable and by means of which the tool is rotatable;
- wherein the tool has at least one linearly movable rod and the spindle comprises a loading device, which acts on the at least one linearly movable rod of the tool, and a pull/push coupling device, by means of which the at least one rod of the tool is couplable to the loading device, the at least one rod being actuable by means of the loading device by pushing and pulling when coupled;
- wherein the pull/push coupling device comprises a clamping jaw and the clamping jaw is arranged in the tool;
- and
- wherein at least one of the tool and the spindle has a rigid tube or a moveably mounted tube for fluid coupling between the spindle and the tool.
