What? How?
Increased play in the milling table spindles can be reduced by
resetting the spindle nuts. The spindle nuts are reset by reduc-
ing the thread flanks of the spindle nut by means of take-up
screws. After the reset, it is necessary to check if there is still
smooth movement over the entire path, otherwise wear is con-
siderably increased due to friction between the spindle nut and
the spindle.
