console are now finally mounted on the spindle nose. The outer
diameter of the distributor ring matches the max. outer diameter
of the chuck. As such, the distributor ring can be centrally aligned
with the chuck using a ruler for complete accuracy, then screwed
onto it.
CAUTION
The distributor ring must be aligned with the outer chuck
diameter in such a way that a radial and axial run-out tolerance
of at least 0.1 mm is achieved.
When detaching the chuck from the spindle nose, the spacing
console remains attached to the distributor ring, and is only
detached from the headstock. No more adjustments must be
made to the positioning sleeves. When detaching the chuck from
