8-4. Air purge
Dew drops may occur in the motor case by ambient environment. In this
case, each component in addition to electric apparatus will fail or rust will
occur. Therefore, the air is purged and exhausted from the air purge
exhaust port.
(Air Hydraulic pressure system)
The air purge is performed by air branched in the NC rotary table from air used for clamp. Thus, air is
used in the motor case from joint with hole of 0.4mm.
Be sure to supply clean air passing through the filter (air filter, mist separator, regulator and drain catcher).
If moisture, oil content, etc., are mixed in the air, its air is entered in the motor case, thus damaging the
equipment. The air in the motor case is exhausted from the air purge exhaust port.
If the air purge exhaust port is closed, condensed drops are not exhausted and pressure is kept in the
motor cover as is, thus causing in motor case damaging and motor malfunction.
Therefore, never close the air purge exhaust port. When exhausting air, although any exhaust sound
occurs, there is no problem.
(Hydraulic pressure system)
Since an exclusive supply port for air purge is provided, be sure to supply clean air as well as the type of
air pressure specifications (Pneumatic: 0.5MPa).
When performing the air purge, block M5 screw hole of air purge exhaust port as shown in the outside
view with the cross recessed round head screw M5 and the seal washer 5. (If not blocked, coolant may
enter in the motor case.)
8-5. Checking device for Clamp/Unclamp
To proceed a secure work, be sure to use Clamp/Unclamp confirmation signals. (See Fig.5)
