Precaution
1. The travel length of the glass scale must
be longer than the maximum travel of the
machine. There should be at least 10mm
of clearance between the ends of the glass
scale and the maximum travel of the machine,
as shown in Figure 1.
3. Indicators must be set up properly to ensure
accurate measurement. Make sure indicator
axis is perpendicular to the work. If a vertical
dial indicator is used, as in
is important to ensure that the dial indicator
is perpendicular to the measured surface to
also avoid the cosine measurement error.
Figures 2 & 3, it
Figure 1. Glass scale clearance.
2. To ensure the reliability of the graduated glass
scale, and to avoid any possibility of scale
misalignment, the scale should be installed
on machined flat surfaces wherever possible.
In the case where there are no machined flat
surfaces available on the machine, machined
flat blocks or the aluminum fillers should be
used. Wherever possible, the scale ends and
the machine reader head should be installed
on a flat surface.

To select proper intallation locations:
1. Scales should be installed on flat machined
surfaces.
2. The opening of the scale must not be installed
in direct exposure to metal shavings, oil,
water, dust or other foreign objects as illus
trated in Figure
should be installed.

4. A clearance of at least 1/8" between the scale
and scale cover is necessary
-
Figure 6. Scale cover clearance.
5. All tapped screw holes must have at least
six threads to allow the screw to be firmly
secured. For the screw that is needed to
secure a heavy load, the tapped holes must
have at least eight threads. After tapping, the
holes must be deburred and cleaned.
(Figure 6).
3. In cases where machined flat surfaces are

not available, an mounting strip or strip
should be used to provide a flat surface for
the installation. The mounting strip, shown
in Figure 5, must be as short as possible to
provide a rigid surface.

6. All cables must be fixed, but also allow for
the maximum machine travel movements.
Figure 7 shows the recommended minimum
radius that should be used for bending the
scale cable.

scale ends, as shown in
Figure 8. Scale alignment measurements.

Requirements
1. Requirements for the mounting surface:
—Parallel mounting
allelism of the two mounting surfaces must
be less than 0.1 mm of each other..
—Perpendicular mounting
two mounting surfaces must be less than
0.1 mm out of square.
