Tube B ending & Endforming Technology
Tracto-Technik, a manufacturer of tube and
pipe bending and fabricating machinery,
has enhanced its 1-axis-controlled tube
bender, Tubobend 90. The mandrel bender
for tubes up to 90mm OD is now available
in a version that features a maximum
bending radius of up to 1,000mm (standard
version: 250mm).
Two of the new machines have been
delivered to customers in Germany, enabling
them to produce not only small radius tube
bends but also precise, large radius tube
bends with maximum repeat accuracy.
The machines are equipped with a
Simatic touch panel control with menu-
driven handling. Capabilities include
automatic sequencing of bending angles
and display of the desired and actual
bending angle.
A measuring system for the length and
rotation position of the tube with digital
display on the control panel is available on
request.
The Tubobend 90 bending machines
also feature freestanding bending heads,
hydraulic collet chucks, hydraulic and
anticipated mandrel retraction, pressure
die assist and a minimal quantity mandrel
lubrication device.
The Tracto-Technik product range covers
CNC tube bending machines up to 170mm
OD, semi-automatic and 1-axis-controlled
tube bending machines, tube end-forming
machines, tube measuring systems, and
piping software solutions.
The company will be exhibiting its products
at EuroBlech 2008 in Hanover, on stand
E30 in hall 11.

J&S Machine, USA, has launched the
CR138-RIMW, a PC based CNC tube/pipe,
angle, and section roll bender. The machine
is the latest in the Tre C product line offered
by the company.
The control (CNW333) used in the new
machine is currently the most advanced
version of the company’s numerical
controls. Consisting of an industrial
computer with Windows XP operating
system displayed on
a 17" colour monitor,
it manages the
programming of up to
36 different radii on a
single part.
Itautomaticallycontrols
over 100 roller rotation
speeds, working on
small bending radii
and complex geometry
such as ellipses,
polygons and bending
by points.
With over 500 automatic positioning speeds
moving both lower rollers, the machine
guarantees high precision in the transitions
between straights and bends or between
one radius and another.
Simple programming is facilitated by
default setup templates for the various
geometries. It is managed by keying in
the radii of the required bends.
Files can be imported directly into the
control using a DXF file format utilizing
the USB interface or network connections
for interfacing with other PCs for the data
exchange.
The operator can quickly setup and start
the machine by using automatic encoder
positioning, photo-eye start detection
and the bending archive creation
function.
