A universal rotating chuck system capable of accommodating multiple small-batch or one-off machining jobs, involving workpieces of different diameter and composition, comprises a rotating chuck having multiple jaws that may be adjusted positionally inward or outward towards the longitudinal centerline of the workpiece or removed entirely. The chuck is rotated by a dual-motor system driving an inner and outer shaft, where the inner shaft is selectively coupled to the outer shafts to rotate independently and adjust the jaws, or rotate alongside the outer shaft to rotate the chuck. In operation, the system is capable of conducting numerous machining operations independent of direct user intervention, including loading/unloading workpieces, loading/unloading tools, measuring tools and workpieces for quality control, and storage.
