Sawing large tubes 10 times faster.
Up to Ø 170mm. How?
Sawing.
Reducing
costs!
A NEW range of tungsten carbide tipped
bandsaw blades, designed for cutting large
cross-sections of metals that are difficult
to machine, has been introduced to the
UK and the Republic of Ireland by US
manufacturer Lenox.
It claims the Tri-Tech CT products are
versatile in their ability to saw accurately a
wide range of materials from high strength
steels to nickel-based alloys and says the
blade’s robust construction results in longe-
vity, high productivity and low cost per cut.
Tri-Tech CT has a proprietary set-style tooth
pattern, and the positive rake provides
strength and durability at the cutting
edge. With each pass, the tooth design
creates three chips that are claimed to be
50% thicker than most other bandsaws.
The sawing action produces straight cuts
and eliminates the pinching and seizing
that can occur when sawing high stress
and work-hardening metals like inconel
and other super alloys.
High grade carbide tips are precision ground
for efficient bandsawing and to balance the
work load across all of the teeth in the cut.
The backing steel of the Lenox band goes
through a detailed preparation process
that minimises body breakage and extends
the life of the blade.
Tri-Tech CT blades are available in fourteen
specifications ranging from 34mm to 80mm
in width and from 1.07mm to 1.6mm thick.
There are five teeth per inch configurations:
0.6/0.8, 0.9/1.1, 1.4/1.8, 1.8/2.0, and
2.5/3.4. Two of these are new, making it
possible to cut high stress metals in an
even wider range of sizes.
Materials processed include high-nickel
superalloys such as inconel, nimonic,
Hastalloy and Waspalloy, iron-based
superalloys, tool and mould steels, stainless
steels, high chrome alloys, titanium, non-
ferrous alloys such as bronze, copper and
brass and aluminium.
Lenox has also introduced a series
of bi-metal bandsaw blades, which it claims
last up to 60% longer than other products
when cutting solid aluminium and alloyed
steels. Marketed under the designation
QXP, they are available in the UK and
Ireland through the existing Lenox network
of distributors.
TheQprefix signifies the proprietarymethod
of manufacture, developed by Lenox, that
improves the blade’s performance and
extends its life. Tooling costs are lower
and productivity is increased, as the blade
needs to be replaced less frequently.
The QXP series is suitable for use on solid
stock of mild to moderate machinability,
such as aluminium, carbon steel and
alloyed steels including stainless and
bearing steels. The deep gullet improves
chip-carrying capacity, enhancing the
blade’s ability to cut at increased speed
and feed rates, while the extreme positive
rake tooth form penetrates material with
less feed force.
QXP blades are supplied in sizes from
27mm to 54mm wide and 0.9mm to 1.6mm
thick. TPI can be 2/3, 3/4, 4/6 or 5/8.
