2.3. Securing the Stage to the Mounting Surface

W A R N I N G : The ANT130LZS 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 ANT130LZS 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 over the entire stage
footprint.
N O T E : The ANT130LZS 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 ANT130LZS. Shimming should be avoided if possible. If shimming is required, it
should be minimized to retain maximum rigidity of the system.
1. Remove the shipping brackets mounted to the sides of the stage with M3 screws. Retain the shipping
brackets for future use.
2. With the stage laying horizontal, push the carriage to the bottom of travel such that the cylinder rods are
mostly hidden in the cylinder bodies as shown in
through an access hole in the stage (refer to
3. Two man step: Slowly lift the stage upright, using the cylinder mounting brackets as a lifting point. Be
careful to not dislodge the loose screw that you inserted in the mounting hole in step 4. Do not lift the
stage by the cylinders, carriage assembly, or cabling.
4. Two man step: Lift the stage to the mounting surface and line the stage up with the mounting holes.
Use a wrench to engage the previously inserted mounting screw. Make sure the screw is fully engaged
in the threaded hole, but do not tighten it at this time. Rotate the stage to align the second hole, insert
another screw, and thread it in without fully tightening. The screw heads should be recessed in the
counter-bored holes.
5. Two man step: Lift the carriage by hand, and hold it up to expose the bottom mounting holes. Insert the
remaining mounting screws. Align the stage per your application, and then fully tighten the mounting
screws.
a. Tightening torque values are dependent on the properties of the surface on which the stage is being
mounted. Typical tightening torque for an M6 x 1.0 socket head cap screw is 7.0 N·m.
