2.3. Securing the Stage to the Mounting Surface
WARNING
: The stage must be mounted securely. Improper mounting can result in injury
and damage to the equipment.
DANGER
:
PINCH POINT!
Keep Hands Clear while the stage is in motion. Make sure that all
moving parts are secure before you move the ECO225SL. Unsecured moving parts could
shift and cause injury or damage to the equipment.
The mounting surface must be flat and have adequate stiffness to achieve the maximum performance
from the stage. When it is mounted to a non-flat surface, the stage can be distorted while the mounting
screws are tightened. This distortion will decrease overall accuracy. Adjustments to the mounting surface
must be done before the stage is secured.
Inspect the mounting surface for dirt or unwanted residue and clean if necessary. Use precision
flatstones on the mounting surface to remove any burrs or high spots. Clean the mounting surface with
a lint-free cloth and acetone or isopropyl alcohol and allow the cleaning solvent to completely dry.
Gently place the stage on the mounting surface.
IMPORTANT
: The ECO225SL is precision machined and verified for flatness prior to
product assembly at the factory. If machining is required to achieve the desired flatness, it
should be performed on the mounting surface rather than the stage. Shimming should be
avoided if possible. If shimming is required, it should be minimized to retain maximum
rigidity of the system.

If necessary, manually move the stage table to access the mounting holes along the edges of the stage.
This stage is designed to use socket head cap screws (SHCS) to secure the base to the mounting surface.
IMPORTANT
: The stage table may offer a considerable amount of resistance when it is
moved manually.
l
If the stage is not connected to a power source, the stage should move freely by hand.
l
Do not attempt to manually move the stage if it is connected to a power source or
includes an integrated brake.
Tightening torque values for the mounting hardware are dependent on the properties of the surface to
which the stage is being mounted. Values provided in
are typical values and may not be
accurate for your mounting surface. Refer to
for mounting locations and dimensions.
