Readjust
An increased clearance in the spindles of the crosstable can be
reduced by readjusting the spindle nuts. Refer to spindle nuts posi-
tion 66 and 71
The spindle nuts are readjusted by reducing the flank of screw
thread of the spindle nut with an adjusting screw. By readjusting a
smooth running move over the whole toolpath is to be assured, oth-
erwise the wear by friction between spindle nut /spindle would
increase considerably.
