EXPRESS 220 S2/320 S2
7. RETRACTION DEVICE
It is strictly prohibited to use the retraction system before the bar feed system is anchored
to the ground. Please read the safety instructions provided at the beginning of this manual
before handling the following devices. Before handling the retraction mechanism, check to
see that the interface cables between the lathe and the bar feeder are long enough.
7.1. Description
When a lathe is equipped with a bar feeder, certain elements (motors, spindle reduction tubes, etc.)
become inaccessible, and sometimes it is difficult, or even impossible, to proceed with their maintenance.
To facilitate these tasks, the bar feeder can be equipped with a retraction system, which allows the
operator to move the bar feeder. The rigidity of the system guarantees perfect alignment when the bar
feeder is in working position. A safety switch impedes any handling as long as the bar feed system is not
in operational position.
7.2. Operation
Conditions: - Bar feed system in
MAN
or
STOP
mode
- No bar between the bar feeder and the lathe
- Pusher inside the bar feeder
- The area around the bar feeder must be clear
Procedure:
1.
Loosen the 4 lock screws
(A)
on the front side of the stand.
2. Pull the bar feeder back.
3. After maintenance, bring the bar feed system back in working position, lock the side screws
(A)
8. 2-POSITION OPTION
When the bar loader must be adapted to a lathe which has no guide bush, this option
(B)
allows the
loader to be moved forward in the direction of the lathe so that it can be connected directly to the spindle.
The software takes the position into account, and saves the
„End Of Bar” (EOB) and the „Top Cut”
positions in a separate memory zone.
Control mechanism of the 2 positions
Adjust both retraction positions with the setting screws
(C)
and
(D)
