Maintenance MPS75SLE Hardware Manual
4.2. Cleaning and Lubrication
D A N G E R : To minimize the possibility of bodily injury or death, disconnect all electrical
power prior to performing any maintenance or making adjustments to the equipment.
W A R N I N G : In applications that have multiple stages bolted together to form multi-axis
systems, the orthogonality may be lost if the stage tables of the support stages are loosened.
Precision aligned stages should not be loosened or disassembled.
W A R N I N G : Further disassembly of the stage is not recommended because proper
assembly and calibration can only be done at the factory. In addition, a laser interferometer is
required for post assembly verification to maintain warranties. Contact Aerotech for more
information.
Cleaning
Before using a cleaning solvent on any part of the MPS75SLE, blow away small particles and dust with
nitrogen or, less preferably, clean, dry, compressed air.
Any external metal surface of the MPS75SLE can be cleaned with isopropyl alcohol on a lint-free cloth.
Harsher solvents, such as acetone, may damage the plastic and rubber seals on the ball-screw or damage
the cross-roller bearing cages. If acetone is required, avoid the screw and bearing seals. Acetone can also
damage the black paint on the motor and encoder covers
W A R N I N G : Make sure that all solvent has completely evaporated before attempting to
move the stage.
Lubrication
Take the opportunity during the lubrication procedure to inspect the precision rail guides for any damage or
signs of wear.
For the bearings, use NSK LG2 grease. Only use the specified grease as other greases may be
incompatible.
If the application process uses only a small portion of travel for most of the duty cycle, periodically drive the
stage through full travel to redistribute the lubrication in the bearings.
For high-speed applications (i.e., near maximum speed at a duty cycle of 50%), frequent maintenance with
standard lubricants is required.
N O T E : Removing the upper axis on an XY, XZ, or YZ system will alter a precision alignment. Do not
remove the upper axis for lubrication and cleaning if possible.
1. Drive the stage table to one end of travel and remove power to the stage.
D A N G E R : To minimize the possibility of bodily injury or death, disconnect all electrical
power prior to performing any maintenance or making adjustments to the equipment.
