The Eagle Bending Machines/BPR
Curvatrici BA CNC series offers substantial
precision and control using a unique set
of servo roll bending controls. The models
BA20, BA35, and BA50 are capable of
producing variable radius bends as large
as required down to a 4-5D degree bend
range that overlaps non-mandrel rotary
compression bending.
The BA CNC series of servo controlled
roll bending machines can be used by
manufacturers who currently utilise CNC
rotary bending equipment. One set of tube
or pipe rolls can be used on the machines
to cover an infinite radius range. Multiple
bends and bend-plains are possible with
this economical method, which compares
very well against multi-axis controlled rotary
compression benders.
Complex parts with multiple radii can be
easily programmed in just a few lines
with the machine. 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, which converts a 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. For
instance, to create a ‘U’ shape, ‘arch 1’ can
be selected. The procedure involves the
input of radius and length of the straight,
followed by sequencing of the load whereby
the operation is complete. The BA direct
radius program automatically blends the
straight and the radius and generates a
graphic representation. Running existing
programs can be just as simple.
When selecting programs, the name and
graphic representation are displayed at
the same time for quick reference. The
operator is only required to select a part
type and operate the ‘load’ control, whereby
production will be set up.
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
changeover. Cycle times range from 10
seconds to 45 seconds per part depending
upon the degree of complexity.
