2.3. Securing the Stage to the Mounting Surface

W A R N I N G : The ANT20G must be mounted securely. Improper mounting can result in injury
and damage to the equipment.
The mounting surface must be flat and have adequate stiffness in order to achieve the maximum
performance from the ANT20G 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 5 µm.
N O T E : The ANT20G 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 ANT20G. Shimming should be avoided if possible. If shimming is required, it
should be minimized to retain maximum rigidity of the system.
When the stage is centered, the tabletop will block access to the mounting holes. With the power
disconnected, gently move the stage to either end of travel to expose the mounting holes.
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
