An extended clearance in the spindles of the cross table can
be reduced by readjusting the spindle nuts.
Spindle nut adjusting screw
Readjusting
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.
