[2] Attachment of the Transported Object
䢢
x
There are tapped holes on the top surface of the slider. Affix the transferred work piece on them.
x
The way to affix follows the installation of the main unit.
x
There are two reamed holes on the top surface of the slider. Use them in case it is necessary to have
repeatability of attaching and detaching. Also, use only one reamed hole on the slider when fine-tuning
such as perpendicularity is required.
x
Refer to the table below for the thread depth and reamed depth. Screwing down further than the screw
depths shown in the table below may destroy a tapped hole or cause a lack in the attachment strength
of the transported object, which may result in the decrease in the accuracy or in a cause of an
unexpected accident.
x
For upper motor type, pay attention to the transferred work piece so it would not interfere with the
motor (motor cover). [Refer to next page]

Tightening Screws
x
Use hexagonal socket head bolts for the male threads for installing the attachment.
x
Use of high–tension bolts meeting at least ISO 10.9 is recommended.
x
Have 1.8 times or more of the nominal diameter secured for the effective length of thread engagement
for screws and mating holes.
Caution: Pay attention when choosing the bolt length. Use of screws with inappropriate length
may cause damage on the attachment holes or not sufficient strength of attachment
of a transferred work piece.
