2.3. Securing the Stage to the Mounting Surface
W A R N I N G : The AMG must be mounted securely. Improper mounting can result in injury and
damage to the equipment.
W A R N I N G : Make sure that all moving parts are secure before moving the AMG. Unsecured
moving parts may shift and cause bodily injury.
The mounting surface must be flat and have adequate stiffness in order to achieve the maximum
performance from the AMG stage. When it is mounted to a non-flat surface, the stage can be distorted as 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.
N O T E :
To maintain accuracy, the mounting surface must be flat to within 1 µm per 50 mm.
N O T E :
The AMG 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 AMG. Shimming should be avoided if possible. If shimming is required, it should be
minimized to retain maximum rigidity of the system.
AMG series stages have a fixed mounting pattern (as shown in
).
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 specific model mounting locations and dimensions.
