Abstract
A machine for working workpieces with a round outer contour by cutting has a coordinate table arranged to displace a workpiece in x-direction and y-direction and having a clamping guide extending in x-direction, a cutting device acting substantially in z-direction, and moving in a predetermined movement region, and clamping arrangement arranged to releasably hold the workpiece on the coordinate table and including a central clamping device arranged on the clamping guide, aligned with the axis of symmetry extending through the center axis of the workpiece, and having clamping elements mounted displaceable in the direction of the axis of symmetry, also including two lateral clamping devices displaceably arranged on the clamping guide, located at opposite sides of the central clamping device, and each having clamping elements which are mounted pivotally about at least one pivot axis extending substantially normal to the workpiece plane and parallel to the z-axis so that the clamping elements can move from a releasing position in which the workpiece and the movement region of the cutting means are released to a clamping position in which they engage the workpiece and vice versa.
