Note :
Ɣ
When applying or removing the finger attachment to the finger, hold the finger attachment
with a tool such as a wrench to support it to tighten the attachment screws to avoid load or
stress applied to the guide part.
Ɣ The heat of the unit is conducted from the fingers to the work part via the finger attachments.
To block heat from being conducted to the work part, use a material with low heat
conductivity such as polyacetal for the finger attachment.
(Reference)
When operated with duty 50%, the temperature rises in approximately 40
qC at the unit
attachment surface (side surface) and finger attachment surfaces.
[Refer to 6.4 Temperature Rises on Main Body and Finger]
