In this process, the workpieces are clamped between at least one upper and one lower clamping jaw (17, 18 and 19, 20) of a first clamping unit (1, 2) such that at least one side can be machined. The first workpiece is transferred from the first clamping unit (1, 2) to a second clamping unit (1, 2), which has at least one upper and one lower clamping jaw (17, 18 and 19, 20). The workpiece is clamped by the second clamping unit (1, 2) in such a way that further machining can be carried out on the workpiece.

The horizontal clamping is then released. This ensures that the workpiece remains clamped during transfer from the first to the second clamping unit (1, 2), thus preventing the risk of bending or twisting of the workpiece, e.g., due to internal stresses.
