Functionality
Step 1: Select suitable bending rollers for the material to be machined and
mount correctly.
Step 2: Connect the ring bending machine to the mains.
Step 3: Turn the main switch from position "0" to "1". The ring bending ma-
chine is now operated via the control panel.
Step 4: Press the "START" key to start the ring bending machine for the ben-
ding process.
Step 5: Screw the upper roller upwards and set a distance between the upper
roller and the lower rollers so that the profile to be bent can be placed
between them (Fig. 17, Form A).
Step 6: Screw the upper roller upwards and set a distance between the upper
roller and the lower rollers so that the profile to be bent can be placed
between them (Fig. 17, Form A).
Step 7: Move the profile to be bent left and / or right. It must be clamped with
one end between the upper and lower rollers (Fig. 17, Form B).
Step 8: Lower the top roller to apply more pressure to the profile to be bent and
to bend slightly (Fig. 17, Form C).
Step 9: Again, move the profile between the rollers and bend.
Step 10: To also pre-bend the other end of the profile, the steps just described
must be repeated.

Check the radius. If the desired radius has not yet been reached, adjust it by
turning the upper roller up and down. Often several operations are necessary.
It must be done carefully so as not to exceed the desired level. Once the desi-
red radius has been reached, the entire profile can be bent.
Step 11: Due to the high bending stress, it may happen that the workpiece
warps to the left or right. To compensate for this delay use the guide
rollers.
Step 12: Due to the high bending stress, it may happen that the workpiece
warps to the left or right. To compensate for this delay use the guide
rollers.
Step 13: After completing the bending process, set the main switch from "1" to
"0" to turn off the ring bending machine.
ATTENTION!
The ring bending machine may only be operated from the
front. The operator and other persons must not stand on the
side of the ring bending machine during bending. The hands
must be kept away from the rollers during operation.
