2.3. Securing the Stage to the Mounting Surface
W A R N I N G : The ANT95L 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 ANT95L 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 ANT95L 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 ANT95L. Shimming should be avoided if possible. If shimming is required, it should
be minimized to retain maximum rigidity of the system.
Access the mounting holes in the base of the ANT95L stage by sliding the carriage all the way to either end
of travel (as shown in
Figure
Four additional mounting holes in the base of the ANT95L are also available for customer use (refer to
Section 2.2.
for locations and
the upper axis to the tabletop of the lower stage. A mounting plate is required if the upper axis is an ANT95L-
050.
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
