2.3. Securing the Stage to the Mounting Surface
W A R N I N G : The ADRT must be mounted securely. Improper mounting can result in injury
and damage to the equipment.
W A R N I N G : Make sure that all moving parts are secure before moving the ADRT.
Unsecured moving parts may shift and cause bodily injury.
The mounting surface must be flat and have adequate stiffness in order to achieve the maximum
performance from the ADRT 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.
N O T E : To maintain accuracy, the mounting surface must be flat to within 13 µm.
N O T E : The stage base is precision machined and verified for flatness prior to stage assembly at the
factory. If machining is required to achieve the desired flatness, it should be performed on the mounting
surface rather than the stage base. Shimming should be avoided if possible. If shimming is required, it
should be minimized to improve the rigidity of the system.
ADRT series stages have a fixed mounting pattern (as shown in
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
