♦
Remember that the minimum bend radius depends on the material to be
bent , the tube external diameter and the wall thickness of the tube.
♦
Correct pressure between
former and counterbending
die. You must apply just
enough pressure to avoid
wrinkles on the inside bend
of the tube.
!!Note: If even with a
higher pressure there are still
wrinkles in the inside bend
use a former with a larger
radius.
♦
In case of excessive
constriction of the tube on its
inside radius use the special
screw on support bracket: as
soon as tube starts visibly
bending tighten screw so
that the screw touches the
back of the counterbending
support bracket. After this
continue the bending process
as normal. Fine adjustment
of this screw will further
improve the bend quality.
!!Remember to adjust the position of this screw for different tube sizes /
materials.
♦
Former and counterbending die must never touch otherwise the tube may break
or have wrinkles on the inside bend and the machine can be damaged.
♦
Do not keep tubes in dusty/dirty places, in these conditions the counterbending
dies will wear out faster due to increased friction between the dirty tube and
counterbending die
