SPRINT 545/565S2
7. RETRACTION DEVICE (option)
It is strictly prohibited to use the retraction system before the bar feeder 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 device which allows the
operator to move it by 250mm. 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
