Abstract
The present invention is a universal workpiece holder that includes a unique positioning hub and a plurality of clamping devices for clamping a variety of annularly shaped workpieces having different interior and/or exterior diameters. The positioning hub includes multiple sets of spokes, wherein when a particular set of spokes aligns with the clamping devices, the workpiece holder is able to secure a particularly sized annulus without distorting it. Moreover, upon rotating the positioning hub about its center and aligning a different set of spokes with the clamping devices, the workpiece holder is able to secure a differently sized annulus. Each set of spokes corresponds to a certain sized annulus, thereby eliminating the need for an independent workpiece holder for each differently sized annulus.
