ABSTRACT:
A vacuum assisted disc clamping device provides a number of fixture rings preferably concentrically stacked on a fixture body that is moveable in fixture ring stacking direction and actuated by a wedge drive to compensate for varying fixture levels associated with the individual fixture rings and disc standards. Each fixture ring includes a planar flange with a vacuum groove and a central conical portion that rises above the planar flange. The conical portion is defined with a diameter and cone angle such that a disc of corresponding dimensional standard may be readily placed on the fitting fixture ring with the disc bottom being sucked onto the planar flange while the disc hole centers on the conical portion.
