Mobile bending systems
JUTEC Biegesysteme GmbH develops
and manufactures tube bending
systems. The standard of Jutec
bending systems, their controls and
machine construction is a result of the
company’s long-standing experience
and continuous development.
The company’s range of mandrel
bending machines includes bending
system solutions up to D = 90mm, with
simple and convenient operation via
a solid user interface, and USB ports
for data exchange. The systems offer
efficient and convenient handling, and
bending radii up to 1.5xD.
For higher output and low downtimes,
Jutec has developed ‘Power Hydraulics’,
which helps reduce the cycle time
per sheet. Using the proven rotation
stopper, which is optionally available, or
the quick-acting chuck, the production
volume of serial parts can be significantly
increased. Dimensional accuracy of
serial products is guaranteed for both
standard parts as well as single parts.
The model 3000 mobile bending
machine for pipe diameters up to 35mm
has received a new
ma i n t e n a n c e - f r e e
three-phase
motor
that is driven by a
frequency converter
and allows power
supply of over 230V.
The motor can be
smoothly
adjusted
in speed, and the
bending tool can
drive backwards with
higher speed, which
leads to shorter cycle
times. The repetition
accuracy is increased,
and the tool can be set
to 0.5°.
The model 6000
mobile bending sys-
tems can now bend
pipes more precisely
to an outside diameter
of 60mm.
The frequency con-
verter technology en-
ables the use of the
machine with 230V with the model
6000S for pipes up to 48mm (the
power supply of 400V for pipes
up to 60mm in the model 6000D
remains unchanged).
In comparison with the previous
model with 400V power supply,
the power consumption of the
three-phase drive is reduced by
around 30 per cent. Using the
menu-driven user interface with
touch screen control, 99 programs
with up to eight bending angles
can be stored. The ramp function (slow
acceleration and deceleration of the
bending axis) increases the precision,
and the bending quality in the starting
and end regions is improved.
All models are available from stock at
short notice.

GRIND Master offers automatic
centreless belt grinding and finishing
machines for belt grinding, bright
finishing and satin finishing of round
tubes and pipes.
The machines have easy settings to
ensure quick changeover from one job
size to another. The floating belt grinding
heads are designed to take care of bend
and ovality in tubes. Up to ten heads are
offered.
An automatic loader/unloader is
available as an option, and machines
are designed for dry grinding as well as
wet finishing.
A wide range of consumables,
including abrasive belts, flap wheels,
non-woven wheels, sisal and cotton
buffs, can be used in predetermined
sequence for achieving the desired
finish.
Tube up to 220mm diameter can
be finished, and the machine can be
supplied with an auto tube size setting,
which requires only two to five minutes
for setting the machine.
Grind Master also offers a six-head
belt grinding and polishing machine for
round bars. From the raw black bar, a
ground and finished bright bar can be
created on this machine. The process
of belt grinding removes surface
defects at higher speeds, compared to
conventional wheel grinding.
VSM ceramic belts for roughing
and compact grain belts for finishing
give consistent finishing results. The
machine can achieve finishes up to 0.12
Ra and h9 tolerance.
