2.2. Securing the Base 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 gimbal.
Do not manually move the gimbal if it is connected to a power source.
l
The gimbal must be mounted securely. Improper mounting can result in injury and
l
damage to the equipment.
When you move the cell manually to do maintenance, this could expose the operator
l
to pinch points. Refer to
The mounting surface must be flat and have adequate stiffness to achieve the maximum
performance from the gimbal. When it is mounted to a non-flat surface, the gimbal 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 gimbal is precision machined and verified for flatness at the factory.
Do not machine the gimbal housing. If you must machine a surface to achieve a
l
required flatness, machine the mounting surface.
Keep the use of shims to a minimum when you mount the gimbal to the mounting
l
surface. The use of shims could reduce the rigidity of the system.

All Frame Sizes
AMG series stages have a fixed mounting pattern (refer to
specific model mounting locations and dimensions.
Tightening torque values for the mounting hardware are dependent on the properties of the surface
to which the stage is being mounted. Values provided are typical values and may not be accurate for
your mounting surface.
