7.2 Adjusting Pad Iron
When adjusting the pad iron, it is aimed at the position restoration of the unnecessary
displacement between the pad iron and the slip sheet and keep the pad iron and the slip sheet
not too tightly between each other. If the pad Iron gets loose, it will
result in the damage of the workpiece and the wear and tear of the
slip sheet, nut and the lead screw and if the pad iron is too tight, it
will cause the hand wheel steering difficulty.
There are two places of pad iron to be adjusted in the CQ0618
Lathe, namely the pad iron of the longitudinal carriage and the pad
iron of the cross slide (as shown in B in the figure). The pad iron of
the saddle has been adjusted properly in the factory before delivery
and it should not be required to be adjusted any more.
