The MultiCut tube cut-off
machine series
MANAGERS responsible for service and
maintenance are normally pragmatic by
nature when it comes to tool life and
repair costs. In practice these managers
improve and modify the equipment
using their first-hand experience on
the factory floor. Sometimes the gap
between the promise from machine tool
builders regarding performance and tool
life seems to be very wide. However,
there are also moments where the trust
in such manufacturers and the faith in
the person you are dealing with will
bring good returns. “We plugged in
the Linsinger MultiCut and it has been
running from the first minute,” recalled
the manager responsible for the
maintenance department of the German
tube specialist Mannesmann Line Pipe
MLP in Hamm.
The start-up of the Linsinger tube cut-
off machine was a textbook installation
in 2004 and has worked since then
continuously without problems. The
construction and installation of the cut-off
machine into an existing and linked pipe
production line was smoothly integrated
by Linsinger and its technicians. The
50 ton machine has shown its pedigree
from the beginning.
With low tool costs and optimised
sawblade life the MultiCut MC 4-610 cuts
the burr-free inner and outer edges of
longitudinal welded tubes in record time.
A logical development of the Linsinger
cut-off machine Multi-Cut MC4,
which works with four independent
controlled drive assemblies, is the
Multi-Cut tube cut-off machine MC3,
which revolutionises the tube cutting
with Ø between 150 and 660mm. The
stationary tube cut-off machine MC3 is
suited particularly for the sampling of
tube end-cuts, and is deployed both for
welded tubes and seamless tube mills.
It possesses three smaller circular
saws, which are fixed on a radial
revolvable disc and deliver a clean,
ready-for-sale
cut.
Considerable
shorter length of cycle results with the
simultaneous engagement of all three
saws in the tube and the afterwards
rotation about 120°; the pure cutting time
for a P110 steel tube of the dimension
244 x 13.5mm is about eight seconds.
Another essential advantage is that if
one sawing station fails, with reduced
line speed the tube line operation
can be continued with the remaining
stations. Furthermore the cutting time
can be synchronised optimally to the
sawblades.
Compared to the large and expensive
sawblades of conventional steel circular
saws, the Multi-Cut-machine can use
smaller and accordingly lower-priced
disposable sawblades.
The longer durability of the smaller
sawblades enables a massive reduction
of the tooling costs, which after 20 years
in use saves many times more than the
cost of the machine itself. Additionally,
the thin cutting width saves material.
The MC3 has fully automated tool
changing performed by a robot after
a present number of cuts. The robot
changes all three sawblades in only 90
seconds.
“The MC3 is state-of-the-art. The
additional charge compared with
conventional saws amortise within two
to three years,” said the managing
director of Linsinger, Hans Knoll.
The tube cut-off machine, Multi-Cut
MC3 and MC4 made by Linsinger have
made the tube cutting technology even
faster and more efficient.
