SFM rafted tube mill
UNIVERSAL Tube & Rollform, a world-
wide supplier of quality tube, pipe and
rollform machinery, is announcing
the availability of a new 3" (76mm) x
0.166" (4.2mm) SFM rafted tube mill for
sale.
This new tube mill was built to
complement its current inventory and
to offer customers in the tube and pipe
industry an additional buying option at a
more affordable price.
The new 3" (76mm) OD rafted tube mill
is equipped with five-roll driven flattener,
forming mill, sizing mill, welding section,
spares and single point adjustment on
the driven stands.
Since the start of the year Universal
has been busy reconditioning machinery
for its customers located all over the
world.
Its latest project involved multiple
tube mill and rollforming lines that were
completely reconditioned using both new
and used materials. This reconditioning
process is a smart alternative, offering
better performance, safety and durability
while keeping the budget in line. The
machine is located at the Universal Tube
& Rollform warehouse in Perrysburg,
Ohio, USA.
Universal offers one of the world’s
largest in-stock selections of used,
reconditioned and new tube mills,
pipe mills and rollforming machinery.
It also stocks high frequency welders,
straighteners, cut-offs, end formers,
deburrers, accumulators and slitting
lines.

Automatic solution for
conic poles finishing
MLW200 TC version, is a round tubes
finishing machine developed by NS
Máquinas capable of automatically
polishing cylindrical and conical tubes
from Ø25mm to Ø205mm.
The machine was designed to
finish conic tubes without any manual
adjustment, making it possible to polish
a complete pole starting with Ø165mm
and ending up to Ø75mm. The machine
also permits the user to finish standard
cylindrical tubes.
The light poles industry was the
original market targeted with this
model, but any application that needs
a consistent surface treatment on conic
shapes can benefit from the technology.
Traditionally, light pole producers
have either manual polishing systems
or centreless belt finishing
machines. The first option is
time consuming and requires significant
labour costs. On the other hand, the
available centreless machines, where
the tube is rotated, show important
safety concerns, as some tubes can be
12m long or more.
With the MLW200 TC the abrasive
belts rotate around the tube giving
flexible finishing without spinning the
tube. This enables the safe working of
both short and long tubes. Additionally,
drilled tubes or slightly out-of-round
tubes can be processed through this
machine. The feeding units feature a
precise diameter compensation system
which, combined with the solid structure,
assures a vibration-free and safe tube
transport operation.
With a water cooling spray on the
finishing area, MLW200 TC can polish
different metals and safely work
potentially explosive materials including
aluminium. An automatic filtration
and pumping system is integrated in
the machine frame and can be easily
removed for cleaning.
MLW200 TC offers a fast and reliable
process up to four metres per minute. It
also assures a constant finishing even
along the longest lengths.
Changing abrasive belts is done in
less than one minute. This brings a very
fast and flexible process for productions
with different poles specifications.
MLW200 TC is equipped with a tube
detection program, which automatically
stops the abrasive belts motor every
time there is not a tube on the finishing
station.
This automatic motor start and
stop system reduces not only the
consumption of energy, but also the
bearings, rollers, v-belts and other
mechanical components.
