Readjusting
An extended clearance in the spindles of the cross table 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. After readjusting a
smooth running move over the entire tool path is assured, the wear
by friction between spindle nut /spindle is reduced considerably.
