INSPIRED FOR TUBE Agricultural machinery
immediately available and we purchased it
with a view to buying a smaller machine later,
as soon as we were able to fill it up.
With the quality level of our products, we are
constantly seeking efficient manufacturing
methods. From this point of view, we certainly
took a bet with the LT JUMBO, mainly as far as
the maximum length of the machinable tubes
(47 feet) which is as important as the maximum
diameter.
Our objective was to obtain the
maximum length possible and
to machine tubes up to 18 m
length so as to produce with a
higher efficiency without worrying
about cut-offs.
At Landoll we had already gained a certain experience
in tube cutting. The experience was
achieved on a steel sheet cutting machine
equipped with an additional module for tube
machining in which we had to manually load
one workpiece at a time.
“Due to this experience, we immediately understood
the significance of having a machine
designed to do whatever we desired in automatic
mode” points out Landoll.
“The greatest surprise that we
had with the LT JUMBO is that,
in the end, it is as fast as smaller
machines. The jumbo processes
a huge quantity of tube in a
24 hours a day, five and half days
a week.”
Ally of robotised welding
The LT8, purchased some time after the LT JUM-
BO as initially planned, is appreciated for its speed
and excellent cut quality, as well as for its loading
and unloading features. The presence of the single
bar semiautomatic loader in addition to the
conventional bundle loader located at the rear
makes it ideal for the several single parts to be cut.
“It is a very useful and efficient configuration”
points out Landoll who continues to refer to laser
systems in general: “We have gained advantage
in manufacturing components that required 90°
junctions that can now be carried out with more
accuracy and in a different manner so as to facilitate
and speed up welding. We now have the
capability to efficient produce holes, slots and
other features on a tube in a single process ”.
One of the best features of the LT8 is the steady
rest being positioned close to the cutting head.
This helps to guarantee the required precision
for automated welding. The facility includes
20 robotised welding units that can be used
only if there are precise components.
Thinking about future investments, Landoll
states: “First of all it is necessary to be able to seize
the opportunities with quality products. All customers
want reliable and easy to use products.
Of course, cost is also important and efficiency
in production must be taken into account. At
present, our sales exceed our production capacity.
We must therefore increase our production
response and control costs and manual that
is quite considerable”.
Certainly, Landoll shows his appreciation for
the BLM Group products and in particular for
laser technology. As for the future, he is rather
optimistic, expecting further investments to
be made in laser systems designed to operate
in the LT8 and LT JUMBO dimensional ranges.
