Securing The Stage To The Mounting Surface - Aerotech ABL1500Z Hardware Manual

Mechanical Specifications and Installation

2.3. Securing the Stage to the Mounting Surface

The mounting surface must be flat and have adequate stiffness in order to achieve the maximum
performance from the ABL1500Z 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.
W A R N I N G : Make sure that all moving parts are secure before moving the ABL1500Z.
Unsecured moving parts may shift and cause bodily injury.
D A N G E R : Strong rare-earth magnets are present in the linear motor magnet track. Loose
metal objects (tools, watches, keys, etc.) may cause personal injury and/or damage to the
equipment.
W A R N I N G : The ABL1500Z must be mounted securely. Improper mounting can result in
injury and damage to the equipment.
N O T E : To maintain accuracy, the mounting surface must be flat to within 2.5 µm.
N O T E : The stage base (or Z-Axis angle bracket) 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.
Procedure for ABL1500Z mounting:
W A R N I N G : Do not attempt to move the carriage of the ABL1500Z until the air supply,
detailed in Section
cause permanent damage to the stage.
1. Prepare the mounting surface and bottom mounting pads of the angle bracket with precision flatstones
to remove any burrs or high spots.
2. Clean the mounting surface and bottom of the angle bracket with the appropriate cleaners (acetone or
isopropyl alcohol for the angle bracket).
3. Place the stage on the mounting surface
4. Tighten the four mounting screws (Figure
screws is 7 N-m.
5. Remove the lifting bracket from the back of the stage assembly (if shipped as a single axis). The lifting
bracket is mounted to the stage with M8-1.25x20mm socket head cap screws.
