Tube B ending & E ndforming T echnology
The Eagle Bending Machines/BPR
Curvatrici BA CNC series of bending
machines provide precision and control
via servo roll bending controls. The models
BA20, BA35, and BA50 are capable of
producing variable radius bends as large as
required down to the 4D-5D degree bend
range, which overlaps non-mandrel rotary
compression bending.
It is possible to use one set of tube or pipe
rolls to cover an infinite radius range. Capable
of an increase in product flexibility, the BA
CNC series is capable of achieving multiple
bends and multiple bend-plains. Complex
parts with multiple radii can
be easily programmed in
just a few lines.
Shortcut function
key commands are
conveniently displayed for
quick reference at the top
of each function screen.
Programming is made even
easier via the dxf key. It is
possible to simply insert a
flash card with a dxf file
into the PC and press one
button to convert the dxf file into a program.
Automated Pro Bending BPR
direct radius software selects
the optimal machine speed for
the quickest production time
for the given part.
The handy ‘figures’ function
screen contains a large
assortment of standard shapes.
In order to make a ‘U’ shape,
the user can select arch 1, input
the radius, input the length of
the straight, and press ‘load’.
The BA direct radius program
automatically blends the straight
and radius, and generates a
graphic representation.
When selecting programs
the name and graphic
representation are displayed
at the same time for quick reference. It is
only necessary to select the part type and
press ‘load’. The BA CNC series has been
specifically designed for ease of use by
operators of all skill levels regardless of any
prior knowledge of computers.
The Eagle Bending Machines/BPR
Curvatrici BA CNC Series servo controlled
roll bending machines are capable of
precisely compensating for material
differences that more basic types of CNC
roll bending machines cannot match.
Typical setup time for repeat work averages
5 minutes for tooling and program change
out. Cycle times range from 10 seconds to
45 seconds per part depending upon the
degree of complexity.

Servo controlled roll bending of parts
 The BA CNC series of bending machines with servo roll bending
controls
 Some of the products manufactured using the BA CNC bending
machines
Each roll is supported by four independent
bearings that allow the distribution of loads
and the alignment of bending axis. Movement
of the rolls is controlled by an electronic unit to
ensure synchronism of the extremities and the
precise positioning of the roll.
Faccin has also introduced software
with a graphical interface to its 4 roll
bending machines. PGS 2000 is a further
advancement of the company’s automation
program for bending systems.
With the Faccin CNC, even an operator
without any experience, following
on-screen instructions, is quickly able to
bend cylinders, ovals and open shapes with
variable radii.

machine’s multi-bearing MCS ensures
reliability and precision of the bending
roll.
Faccin, Italy, is the manufacturer of the
4HEL series plate bending machine with
computerised numerical control model
PGS 2000. The machine
is provided with all
accessories necessary
to allow the machine to
combine high accuracy
and speed of execution of
the workpiece, even with
complex shapes.
To perform high quality
pre-bending operations,
the machine features
rectilinear guides: the
frame is designed with
strong guides where
the rolls support slide
during movements. The
