Multi-spindle machine tool

A multi-spindle machine tool comprising a machine frame, a spindle drum arranged on the machine frame to be rotatable about a spindle drum axis and having a plurality of workpiece spindles, each of which is provided with a workpiece receptacle for a workpiece that is to be machined in a working area, a plurality of tool carriers arranged in the working area, associated with individual spindle stations, and each tool carrier having a tool holder receptacle into which a tool holder is insertable, thereby providing a plurality of tool holder receptacles and a plurality of tool holders, and a machine control system for controlling the machine tool,

• wherein a handling apparatus is arranged on the machine frame, wherein with the handling apparatus, also controlled by the machine control system, at least one of the tool holders is at least one of i) insertable into at least one of the tool holder receptacles and ii) removable therefrom,
• wherein each tool carrier has a tool carriage with a tool holder receptacle into which the tool holder is insertable in an inserting direction which lies in a plane extending transversely to the workpiece spindle axis,
• wherein the tool holder has a hollow-shaft cone which is insertable into the tool holder receptacle having a conical receptacle, and
• wherein in the clamping position, the clamping unit draws the hollow-shaft cone in the direction of the conical axis into the conical receptacle and presses it radially to the conical axis against the conical receptacle.
