Installation of Linear Glass Scales
Mounting Linear Glass Scales
C1.0
Make sure that the mounting surface is dry and clean.
C1.1
Align the scale by placing the edges against the
benching pins.
C1.2
Optionally, scale clamps may be used to secure the
scale while the adhesive cures. (PN:160-00002)
C1.3
Apply a hard epoxy, such as Tra-Con’s Tra-Bond 2116,
at one point on the scale. If no end benching pin is
used, epoxy at the index mark is suggested. If an end
benching pin is used, epoxy at the end of the scale
where the pin is located is suggested. Then apply 100%
Silicone RTV adhesive around the edges of the scale.
C1.4
Do not allow epoxy to seep under the scale as this will
affect scale flatness and therefore, encoder accuracy.
C1.5
After adhesive curing, remove the scale mounting clamps.
NOTE:
Tra-Bond 2116 and RTV not recommended for vacuum applications.
