Machine tool, in particular multi-spindle milling machine

A machine tool, comprising:

• a machine frame;
• a workpiece clamping device for clamping a workpiece;
• an axis slide assembly which is arranged on the machine frame and which is configured to linearly move the workpiece clamped at the workpiece clamping device by way of three controllable linear axes;
• and
• a spindle carrier assembly which is arranged on the machine frame and has at least two tool-carrying work spindles;
• wherein the work spindles are arranged on a turret which can be rotated or swiveled about a turret axis at respectively equal distance from the turret axis and the spindle axes of the work spindles are aligned or can be aligned in parallel to one another and in parallel to the turret axis,
• wherein a first tool-carrying work spindle and a second work spindle of the at least two tool-carrying work spindles are arranged in relation to the turret axis on the opposite side at the rotatable turret, the turret axis being aligned horizontally, and
• wherein the first work spindle is positioned at a machining position of the machine tool when the second work spindle is positioned at a tool change position of the machine tool, and the second work spindle is positioned at the machining position of the machine tool when the first work spindle is positioned at the tool change position of the machine tool.
