Cutting, Sawing & Saw Blades
Circular saw blades
STARK SpA leads an industrial group
specialised in HSS and TCT circular saw
blades for a full range of metal cutting
applications. A strategic network of
distributors and agents grants customers
commercial and technical support at any
time.
The Millennium HSS blade is the
company’s latest solution for tube cutting
with high tensile strength steel, high
temperature in the cutting area, internal
scarfed tubes, and low cutting time for high
line speed production.
Stark claims that in all these cases the
HSS Millennium blade is able to achieve
longer life, compared with other standard
HSS blades; the material of the blade
together with the coating and the low
production tolerances help to obtain results
in durability and cutting time.
The Premium TCT blade is suitable for
use in tube cutting where even the best
HSS blade is not adequate in cutting time
or in pieces to be cut. The blade features
a specific PVD coating developed by Stark.

Nanocomposite coated blades
offer improved tool life
ICO Surface Coatings, a division of Tru-Cut
Saw, has developed a new nanocomposite
PVD coating to increase blade life for
circular ferrous and non-ferrous saw blades.
Saw blades coated with the new ViTA-
Nano material will run a claimed 30%
faster, with lower cycle times and increased
production rates compared to AlTiN coatings.
Richard Otter, VP sales ICO Coatings,
commented, “Flying saw machines, re-cut
machines and high production sawing
machines will see immediate cost benefits
in longer blade life when sawing with the
ViTA-Nano coating. We’re working hard to
ramp up production and currently are PVD
coating about 600 blades per day.”
ViTA-Nano blades are more effective
than AlTiN when sawing hardened steels,
cast iron, aluminium and super alloys, and
are able to withstand temperatures that
are 300°C (550°F) hotter. The blades last
longer because edges are protected for a
longer period of time from steel build-up
that ultimately reduces tool life. ICO Surface
Coatings recommends dry cutting with VITA-
Nano blades to further reduce coolant costs.
The company’s research and
development centre is currently working
on the next generation of super hard ViTA-
CrX nanocomposite coatings for industrial
sawing applications.
ICO Surface Coatings offers PVD coating
and re-coating services for all types new
and used tools and wear parts. Equipped
with state-of-the-art coating chambers
and carousels, ICO offers both standard
and special surface treatments. Standard
coatings are CrN, TiN, TiCN, AlTiN-ML, AlTiN-
XL, AlTiCrN and TiAlCN Phoenix™. Special
and tool-specific coatings can be individually
tailored to specific customer requirements,
and coating chambers can handle part sizes
up to 1,250mm OD x 700mm.

A new generation of laser cutting equipment
THE Stiefelmayer effective laser cutting
machine integrates technologies that make
it both efficient and productive.
Modern lasers require less power for
cutting yet have three times the degree
of efficiency and are suitable for thinner
sheets. They also allow greater cutting
speeds.
To translate these higher cutting speeds
into shorter production times, the machine
was upgraded to use the
latest technology, setting new
standards for dynamics and
precision. The weight of all
moving parts was optimised
by using modern materials
developed for aerospace
and racing applications.
These contain carbon
fibres to achieve superior
strength with minimal mass
– a prerequisite for high
contour accuracy at high
cutting speed.
In combination with high-performance
linear motors, products are manufactured
quickly with great precision.
The fibre guide transfers the precision
of the machine to the component without
deviation. Fibre systems are completely
sealed and so require no maintenance; no
flushing of the beam path, no reflectors to
adjust, and no special gas for the laser.
The machine features a conveniently
operated table system with fast table
changeovers and a user-friendly operating
interface.
