Abstract
In order to improve a machine tool comprising a machine frame with an underframe and a machine column seated on this and having a support ring, a support mounted on the support ring for rotation about an essentially vertical axis, several workpiece receiving chucks for workpieces to be machined arranged on the support, an operating area extending around the vertical axis, and a plurality of stations arranged on the machine frame in the region of the operating area, the workpiece receiving chucks being positionable in these stations during a machining cycle, such that the machine frame has as great a rigidity as possible with as expedient a construction as possible it is suggested that the machine column have a reinforcement casing fixing the support ring in relation to the underframe, this casing extending outside the operating area and surrounding it at least partially, that the reinforcement casing comprise casing supporting structure elements which are located in a casing surface extending around the vertical axis, absorb forces acting in this casing surface and transferred from the support ring in a manner rigid against deformation and are connected with one another to form a casing surface supporting structure rigid against deformation.
