An indexing fixture adapted for operation with an internally held collet-receiving work piece and having means for both indexed axial rotation and indexed axial tilting in a vertical plane has certain moving parts which may be adversely affected by grinding wheel dust shielded by other members less liable to damage. Also, adjustable means is provided for influencing certain elements to compensate for abrasive dust damage. A selectively positionable indexing dog enables the establishment of a rotary indexing position of an associated work piece along its radius or diameter.
