Abstract: A machine tool with a chain magazine has a chain guide which extends in the x, y, and z-directions. It also has a magazine chain, which has chain members, which are connected to one another by means of universal joints and in each case have a tool receiver. The magazine chain is guided by means of the chain guide. The chain magazine is moveable in the z-direction for tool changing operations.

Abstract: A machining installation for workpieces comprises a workpiece positioning device comprising a workpiece holder pivot unit as well as a tool positioning device comprising a tool holder pivot unit. The workpiece holder pivot unit is designed such that a workpiece holder is pivotable about at least three and no more than four workpiece holder pivot axes. Moreover, the tool holder pivot unit is designed such that a tool holder is pivotable about no more than two tool holder pivot axes. The machining installation has a simple design and ensures flexible and accurate machining of workpieces.

Abstract: A machining installation comprises a workpiece positioning device with a workpiece holder pivot unit which is designed in such a way that a workpiece holder, together with a workpiece to be machined, is pivotable about at least five pivot axes. In order to rotatably drive a tool about an axis of rotation, a work spindle unit is arranged at a stand, with the axis of rotation being inclined relative to a horizontal x-direction through an angle ?, with 20°???70°, particularly 30°???60°, and particularly 40°???50°. The machining installation has a simple design and allows a flexible five-sided machining of workpieces.
