Readjusting
An extended clearance in the spindles of the cross table can
be reduced by readjusting the spindle nuts.
Abb.5-4: Spindle nut X - axis (milling table faded out)
The spindle nuts are readjusted by reducing the thread flanks
of the spindle nut by means of a regulating screw. Due to the
readjustment it is necessary to check if a smooth movement
over the whole travel is still given, otherwise the wear is con-
siderably increased due to the friction between the spindle nut
and the spindle.
The regulating screw of the spindle nut of the Y axis is acces-
sible from the rear side, the regulating screw of the spindle nut
of the x axis is accessible from the right or left side of the mill-
ing table.
