Technology Update
Bewo Cutting Systems BV, the Netherlands,
has introduced the SCF-90 Quatro cutting
system that offers innovative technology
and improved performance. With 75 years
of experience, the company was recently
acquired by Nivora Holding BV.
The SCF-90 Quatro features complete and
automated fast changeover, with extremely
high output figures and a new state-of-the-
art centralised control system. The newly
designed full CNC length control feeding
system enables the user to cut up to 4
or even 5 tubes at a time, with capability
to handle round, square or rectangular
tubes.
The SCF 90 Quatro has been fully designed
and developed in-house by Bewo’s highly
skilled and experienced engineering
department. The working space has been
screened entirely, resulting in minimum
sound levels.
The transparent protective
hoods can easily be opened if
the total line has been entirely
shut down. This machine
adheres to all CE security
certification rules.
The Bewo ‘Prisma’ jaw system allows
four point clamping on round, square
and rectangular tubes, together with
simultaneous clamping of multiple tubes.
A load cell and camera system takes care
of a continuous and reliable production
process.
Additional links such as brush deburring,
measuring, tube washing and different tube
packaging systems can be fully integrated
into the machine control. A complete
SCF-90 Quatro cutting line, including
deburring, measuring, washing and stacking
can handle an output up to 6,000 pieces per
hour.
The new Bewo SCF-90 Quatro cutting
line offers optimal flexibility, to enable the
suppliers of added valued fixed lengths to
stay competitive in the market.

Variable wall tube drawing line
for drill pipes
George A Mitchell Company, USA, has
recently delivered a highly sophisticated
225,000lb capacity variable wall tube
drawing machine complete with a 250,000lb
three die tube push pointer and unique tube
handling system to a major tubular parts
manufacturer in North America.
 Mitchell variable wall tube drawing line, including
250,000lb three die tube push pointer, 225,000lb
variable wall tube drawing machine and special
tube handling system
The line was designed primarily to produce
variable wall core drill blank tubes in
multiple lengths. Core drills are used in
mineral exploration. The line is scheduled
to be in full production in 2009.
With so much emphasis on weight savings
and enhanced material properties, variable
wall tubes allow more core drills to be
transported to the work site per transport
load than the previous style of core drills.
Furthermore, the weight savings linked to
variable wall tubes also allow deeper drilling
depths. In addition, the cold working of the
material via the drawing process enhances
the body strength of the core drills.

Tube straightening and cutting machines
Ravni Technologies, France, is the manufacturer of a complete range of tube
straightening and cutting machines for coils with a diameter range of 1 to 24mm. The
tube processed using this machinery is steel, stainless steel, copper, and coated tube.
The standard line includes a single or double motorized decoiler that is synchronized
with the machine. A feeding station with caterpillars enables a feeding speed of up to
180m/min and a chipless cut-off unit.
An independent encoder measures
the length – the tolerance level
is ±0.3mm over one metre. The
components of the line are designed
for easy use. All machine functions
can be found on the user-friendly
control panel, which monitors and
displays the different stages of the
production process in detail.
As with all the company’s machine
models, the MDC10-Tucm is
designed for fast tool changeover.
The straightening rollers, settled on a rotating table, are adjustable and equipped with
digital indicators to recover the appropriate regulations for every diameter.
A digitized tube chipless cut-off unit can set the speed and depth of penetration of the
wheel into the tube according to the thickness. The advantages of this new technology
are traceability and control of the process.
Ravni Technologies can provide worldwide installation, training and set-up of the
machine.
