  • Patent number: 9694461
    Abstract: A transfer center for machining at least one workpiece is disclosed, having a machine frame, having a plurality of preferably stationary machining spindles arranged in the machine frame—particularly in a machining head, having a workpiece carrier on which at least one workpiece to be machined is arranged by means of a respective clamping device, and having a workpiece manipulator arranged in the machine frame, onto which workpiece manipulator the workpiece carrier is flange-mounted and which is movable by drive means in at least one spatial direction in relation to the machine frame. To achieve a high machining accuracy in parallel machining, according to one proposal, the transfer center—in order to compensate for a deviation between the actual position and the desired position of the workpiece or workpieces—has a position compensation system with at least two pressure elements situated between the workpiece or workpieces and the machine frame, whose operating directions enclose an angle with each other.
