A collet assembly for picking and placing a disc pack in an automated assembly process, the collet assembly having a retractable cylinder that extends to spreadingly engage a segmented collet against a lifting surface of the disc pack to support the disc pack during a lifting operation. The collet assembly is positioned by a positioning assembly to an engaging position adjacent the disc pack. A locking cylinder supports a lower pad and an upper pad on opposing sides of a flange portion of the collet assembly, to provide a fixed mode in a retracted position of the locking cylinder wherein the collet assembly position is fixed relative the positioning assembly, and to provide a compliant mode in an extended position of the locking cylinder wherein the collet assembly is free to compliantly float in a two-axis plane relative to the positioning assembly.
