Orienting the Angle Head for Single Position Machining
Initial Orientation: Because the tool changer typically loads the tool against the same side of the keyway each cycle, it is important that the tool is loaded into the machine spindle by the tool changer not by hand, prior to final adjustment.
Final Adjustment: The head (E) is attached to the shank (F) by means of a clamp collar(G). By loosening the four clamp collar screws (H) the head can be rotated 360 degrees to the desired orientation. See Figure.
Typically a dowel or gage pin is chucked in the collet and swept with an indicator for precise positioning. The flat around the spindle is also very square to the centerline of the tool and often can be used to indicate.
