Better saw length and performance
HSS circular sawblades for precision
and improved surface finish
JULIA Utensili, Italy, a specialist in HSS
circular sawblades, produces a wide range
of sawblades with diameters from 20 to
620mm for tube cutting.
Recent investments in modern production
systems have increased the company’s
total production capacity and improved the
quality of the products, it claims.
In order to remain competitive, it says
it has reduced production costs by fully
automating its production plant.
MACHINE saw manufacturer Trennjaeger,
Germany, has unveiled its new SPA range
of products, which feature saw blade
stabilisers, zero backlash heavily pre-
stressed spur gearing and hard metal
production sawing facilities, which can now
deal with materials up to 160mm thick with
Results from the company’s investment in
research and development include the new
Silver Fox surface coating, which is designed
to provide better performance than traditional
PVD coatings, especially in those applications
with high-speed cutting parameters.
Close collaboration between the technicians
of Julia Utensili and those of leading
machine manufacturers has also allowed the
development of increasingly sophisticated
software for the precise calculation of the
best cutting parameters.
a tensile strength of up to 2,200Nm, with
automatic handling and storage/stacking.
Marking, deburring and sorting, as well
as chamfering and centring associated
with drilling, are also implemented, as are
the automatic database steering of the
These improvements have already been
applied to the most recent generation of
sawing machines, enabling better sawing
performance and longer tool life.
The company states that, in comparison
with friction saws, HSS sawblades can
offer a higher degree of cutting precision
and better surface finish, and believes
they are more competitive in comparisons
of the most expensive cut with carbide
tipped sawblades.
