ABSTRACT:
In an apparatus for manipulating workpieces in an electron beam drilling machine, workpieces are mounted on rotatable disks which in turn are mounted on a housing which is rotatable and translatable. Each disk, as a fixture holding the workpiece, is unlocked, rotated, and locked in a new position by the motion of a single driving member and associated elements. The single driving members associated with each workpiece indexing assembly are driven through a system of gears from a single central shaft which passes through the vacuum chamber wall to externally mounted actuators and controls.
