3.1.1 General
Cautions
When mounting close to other equipment, ensure that the travel of the
platform being driven is not obstructed. If movement is obstructed the
actuator will stall, which could cause premature wear failure of the drive
screw coating.
The actuator tip is a tungsten carbide ball with a superior finish and wear
resistance. Where possible, the contact area and torsional resistance of
the actuator should be minimized by using a flat, smooth, hard surface
(e.g. hardened steel or ceramic) for the ball to push against. Avoid
pushing against soft material, e.g. aluminum or brass.
Use grease as required between the ball and the contact area. If the
pushing surface is not hard enough, or there is excessive friction at the
ball contact point, this could result in significant wearing of the contact
pad and consequently increased torsional resistance against the drive
screw.
When considering the stage movement in the proximity of other objects
or equipment, ensure that movement of cables connected to the moving
carriage is not impeded.
