For example, the Duet 125 automatic
cut-off saw can reach hourly production
rates of around 2000 pipes of 150 mm in
length + sockets and more than 2300
pipes/hour of 500 mm length + sockets. At
the same time, the system also guarantees
the necessary cut length precision (toler-
ance of ± 1 mm) thanks to the machine's
CNC control system. This system allows
perfect synchronization of the cutting unit
with the pipe extrusion speed and conse-
quent exact positioning of the unit at the
required cutting dimension. Moreover, the
machines are equipped with specific anti-
wear tools to guarantee exceptionally high
and enduring quality of the cutting/cham-
fering process.
The logical control system also offers ‘on
the fly’ cutting capabilities (Sica patent
EP129515), optimizing the use of the ef-
fective stroke to further increase output
in terms of the number of cuts/hour.
Equipped with an intuitive icon-based
graphic interface and a classic produc-
tion system for preset sequences of
lengths, the machine also features a new
length sequences management system.
Specifically, having entered the basic pro-
duction parameters (extrusion speed,
pipe diameter, capacity of downstream
machines) the user can define the re-
quired production batches, automatically
optimized by the system in order to ex-
ploit the machine's potential to the full.
Intelligent planning of production se-
quences in addition to the availability of
libraries in which process parameters and
user product dimensions can be stored,
determines the definition of a new state
of the art field in terms of versatility and
ease of control.
Given the large number of cuts that can
be performed per unit of time, the ma-
chine has been equipped with an extra-
powerful cyclone-type dust exhausting
system.
The range of automatic in-line planetary
saws in the Duet series (available in the
Duet 125, Duet 160 and Duet 200 ver-
sions) includes the Duet/K (cutting with
knife without material removal for HDPE
and PPR) and Duet/C (cutting with cham-
fering unit and knife without producing
chips inside the pipe) versions, in addi-
tion to the standard model for PVC.
Duet/C is particularly suitable for PP lines
equipped also for the production of dou-
ble-joint pipes.
The machines are entirely based on elec-
tro-pneumatic design eliminating all pos-
sible problems linked to the use of hy-
draulic actuators and hydraulic power
packs, and are configured in order to op-
timize total energy consumption.
With this range of saws Sica responds to
market demands for cutting at high ex-
trusion speeds with reduced energy con-
sumption, ease of use and control.
