How?
An increased clearance in the spindles of the cross table
can be reduced by readjusting the spindle nuts.
Spindle nut adjusting screw
Readjust
The spindle nuts are readjusted by reducing the flank of
screw thread of the spindle nut with an adjusting screw. By
readju-sting a smooth running move over the whole toolpath
is to be assured, otherwise the wear by friction between
spindle nut / spindle would increase considerably.
The readjustment screw of the Y axis can be attained from
the backside, the readjustment screw of the spindle nut of the
X axis can be attained from the right or left side of the milling
table.
An enlarged clearance in the spindle of the Z-axis can be per-
formed by reciprocal turning of the spindle nut.
Spindle nut turnable at the bottom
Readjust
By readjusting a smooth running move over the whole
toolath is to be assured, otherwise the wear by friction
between spindle nut / spindle would increase considerably.
Turn the crank of the drilling-milling head as low as
possi-ble.
Firmly clamp the clamping lever left and right.
Remove the maintenance lid on the column.
