Abstract
The adjustment device comprises three rings (15, 16, 17), whose inside diameter is greater than the outside diameter of the part of the hollow workpiece (5) on which the chamfer (10) is to be machined. The support ring (15) is fastened in a substantially centered position on the workpiece (5), and carries support assemblies (20) for the orientation ring (16). The assemblies (20) make it possible to adjust the position of the orientation ring (16) in the direction of the axis (8) of the workpiece (5) and its orientation in relation to the cross-sectional planes of the workpiece (5). The adjustment ring (17) is mounted for adjustment in position on the orientation ring (16) in the plane (11) of connection of the chamfer (10). The machine is adjusted with the aid of comparators (59, 60) whose sensors come into contact with reference surfaces (17a, 17b) of the adjustment ring (17).
