Fitting the "Z" axis scale:
Before mounting the "Z" axis scale, ensure that it
will read "+" as you wind the table down, increas-
ing the distance from the table to the cutter.
1.
The "Z" axis scale should be installed on the
side of the column, ensuring that the open
side of the scale is away from the direct metal
shavings and coolant and that the travel is
in the right direction, "–" towards the spindle
and "+" away from the spindle. The bracket
should be mounted on the knee (Figure 21),
and around the scale to allow for the cover to
protect the scale (Figure 22), where exces-
sive coolant and metal shavings are present.
