Wires for multiwire machines
 Our extensive experience in many different
types of stone work across the world,
combined with our strong local commitment
in respect to service and support has
given us unique know-how. It is this
know-how – regardless of whether
it concerns different varieties of
stones, machines or types of tools – that
enables us to develop tools with maximum
efficiency and reliability.
The recent
launch of multiwire machines is the
opportunity for Diamant Boart to
put on the market a new diamond wire
specifically designed for these machines
and which is of the high quality that
is required for this application.
To saw a granite block into thin slabs,
the classical procedure using a grit-set
frame is often chosen
for two main reasons, namely a very
competitive
cost and a well understood procedure.
However, the drawbacks remain obvious
: limited productivity (7 cm/h) and
thus poor flexibility, water recycling,
labour costs, an increase in the
sawing cost per m2 for thick slabs,
the large installation area.
It is for these reasons that this
application has been the subject
of numerous attempts to develop machines
fitted with diamond tools, that have
now lead to
the marketing of multiwire sawing
machines.

ADVANTAGES
With the new
wires customers gain a decrease in
the sawing costs and a improved productivity.
Moreover, to avoid the long and costly
remounting operations the 7.3 mm
is “one
use”.
RECOMMENDATIONS
For optimum
use the following is necessary :
- The
blocks have to be squared at the
top
and the bottom before sawing.
- The
minimum block length has to be
2.5 m
or more.
- The blocks have
to be installed and cemented
on three supports
CHARACTERISTICS
The standard wires for multiwires
machines are injected with transparent
plastic and they contain 36 beads/
m.
In general, they are not sharpened. |
