2.3.2 Installation of Slider Type

[1] Attachment of Actuator Body
The attachment surface should be a machined surface or a flat surface that possesses an
equivalent accuracy, and the flatness should be 0.05mm or less. Also, the platform should have
a structure stiff enough to install the unit so it would not generate vibration or other abnormality.
Also consider enough space necessary for maintenance work such as actuator replacement
and inspection.
There are datum surfaces for attachment on the base.
The flatness of the slider movement is designed to be 0.05mm/m at maximum to the datum
surface.
On the rear side of the actuator, there are tapped holes and through holes for attachment and
reamed hole and oblong hole for positioning. See the appearance drawings for the details of the
position and diameters. [Refer to Chapter 9]
Utilize the reamed holes when repeatability in the attachment after detaching is required.
However, when small tunings such as the perpendicularity is required, consider such things like
to use one reamed hole.
