<p>The invention relates to a system for producing dental mouldings from blanks, which has a machine tool for machining a blank (2), and also a workpiece holder (4) for securing the blank (2) during machining. The machine tool has in this case a mount (6) for the workpiece holder (4), and the workpiece holder (4) has a shank region (8) which can be inserted reversibly into the mount (6) and in the inserted state can be secured in position in the mount (6). Furthermore, the system has a lever element (12), wherein the system is configured so that the lever element (12) can be clamped between the mount (6) on one side and the shank region (8) on the other side in order to secure the shank region (8) in position in the mount (6). With such clamping of the lever element (12), a particularly high clamping force, by way of which the shank region (8) of the workpiece holder (4) can be secured in position in the mount (6), can be produced.</p> |
