Rklf End Clamps - Renishaw ATOM Installation Manual

RKLF end clamps

The end clamp kit is designed to be used with Renishaw RKLF scale to ensure the scale is mastered
to the substrate. Alternative narrow 6 mm wide end clamps (A-9523-4111) are also available.
NOTE: End clamps can be mounted before or after readhead installation.
1. Clean ends of scale and the area where end clamps are to be fitted using Renishaw scale
wipes or one of the recommended solvents (see
2. Thoroughly mix up a sachet of RGG-2 two part epoxy adhesive and apply a small amount
to the underside of the end clamp.

3. The end clamp features two small regions of contact adhesive. These will temporarily hold the
end clamp in position while the epoxy cures.
CAUTION: Ensure that excess epoxy is wiped away
from scale as it may affect the readhead signal level.
4. Remove the backing tape from either side. Immediately position end clamp over the end of
the scale and push down to ensure complete adhesion. Allow 24 hours at 20 °C for full cure.

To ensure scale end movement of typically < 1 µm, stabilise the system at least 5 °C higher
than the maximum customer application temperature for a minimum of 8 hours. For example:
Customer application = 23 °C axis temperature. Stabilise the system at 28 °C for a minimum of 8 hours.
