ABSTRACT:
In a positioning and turning apparatus for the machining of heavy workpieces, the problem of inaccuracies caused by bearing play and drive stresses and standing in the way of a sensitive and accurate setting and thus the use of numerical controls and controlled positions is eliminated by using ring bearings with a large cross-section which can be used as compact building units and connected to large drive-geared wheels, resulting in a definite gain as regards rigidity, freedom from play and precision. With a cross carrier on the carrier of a positioning and turning apparatus, the workpiece is translatorily movable in addition to its rotatability around two axes, being adjustable particularly with respect to the axis of rotation so that an optional radius can be set in the case of curved machining like, for example, curved welding seams.
