ABSTRACT:
A rotatable offset indexable fixture is rotatable by being mounted on a work spindle. A faceplate is journaled on the fixture for rotation about an indexing axis parallel to but spaced from the workpiece spindle axis. A workpiece may be secured to the faceplate. First and second cooperable toothed coupling members are concentric with the indexing axis and one is fixed to the rotatable workpiece spindle and the other fixed to the faceplate so that they rotate together about the spindle axis when coupled together. A fluid-actuated piston is provided to relatively move the coupling members along the indexing axis to couple and uncouple the members and for independent rotation of the second coupling member when uncoupled. A first aperture may be machined in the rotating workpiece concentric with the spindle axis and then the faceplate indexed to a second position and a second aperture machined concentric with the spindle axis at a location spaced from the first aperture.
