8. Table Clamp
8-1. Precautions for table clamp
Be sure to rotate the table with the table unclamped and use the table
with it clamped when machining after positioning. If the table is operated
by mistake, take care since the worm wheel may be damaged. Check
the signals of pressure switch to check Clamp/Unclamp operations.
Never operate the table at clamping torque or more in specification
column because the clamping part will be worn and the worm wheel also
will be damaged.
Clamped status is not canceled completely when residual pressure
remains while unclamping. Thus, the table operation may continue
under half clamped condition. Since the above mentioned case leads to
the seizing of worm gear and clamped part, take extreme care of back
pressure.
In case of especially hydraulic clamp, design the circuit so that back
pressure is less than 0.2 MPa while unclamping.
If a silencer is clogged with cutting fluid etc., there are possibilities that
compressed air may not be exhaust and it leads unclamp failure alarms.
To avoid clogging, maintain silencer periodically.
