2.2. Securing the Stage to the Mounting Surface
DANGER: Mechanical Hazard!
Personnel must be made aware of the mechanical hazards during set up or when you
do service to the stage.
l
Do not manually move the stage if it is connected to a power source.
l
The stage must be mounted securely. Improper mounting can result in injury and
damage to the equipment.
l
When you move the tabletop manually to do maintenance, this could expose the
operator to pinch points. Refer to
Pinch Points on Page 12 .
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 stage is precision machined and verified for flatness at the factory.
l
Do not machine the stage housing. If you must machine a surface to achieve a
required flatness, machine the mounting surface.
l
Keep the use of shims to a minimum when you mount the stage to the mounting sur-
face. The use of shims could reduce the rigidity of the system.

APR100DR series stages have a fixed mounting pattern available to secure the stage to a mounting
surface.
Figure 2-2 shows the main mounting holes in the base of the stage. 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
Table 2-2 are typical values and may not be accurate for your
mounting surface. Refer to Section 2.1. for specific model mounting locations and dimensions.
