SAGEN-MEHRING GmbH, an international
saw blade manufacturer, says its new RIX
Formula SPF line achieves higher cutting
speeds and feed performance as well as
offering more consistent sawing and higher
wear resistance.
The performance of the RIX Formula
SPF saw blade was recently documented
in a number of cutting tests with one
of Germany’s leading sawing machine
manufacturers. The tested blade offered
combi-toothing from 0.75 to 1.25 teeth
per inch, was 1.6mm thick and 80mm
wide. An alloyed case-hardened steel of
quality 1.6587 – 18CrNiMo 7-6 according
to the DIN EN ISO standard 683-17 with a
diameter of 655mm was cut as part of the
test series.
The RIX Formula SPF saw blade
accomplished this in a cutting time of
9.6 minutes with a cutting speed of 84m
and a feed rate of 68mm per minute. By
comparison, a conventional bi-metal saw
blade took 82 minutes with a cutting speed
of 31 metres and a feed rate of only 8mm
per minute.
Markus Döring, chief executive officer
of Sägen-Mehring GmbH in Hockenheim,
Germany said: “We achieve the high
performance of our saw blades by paying
careful attention to the surface finish of
the edge material. This also requires
sophisticated process technology for the
finishing of our cutting edges. Of course, the
backing material, and even the toothing of
the edge material, also play a role, although
they are of lesser importance.”
The company says that the coatings
applied to the edge material can only come
into full effect after the finishing of the cutting
edges. The functional surface of the bi-metal
saw blade attained in this way provides
optimal guidance in the cutting channel,
which results in a high red hardness, which
in turn allows a higher cutting pressure to
be exerted on the material. The result is
particularly high wear resistance, top feed
performance and high cutting speed.
A time-consuming slitting process
can also be eliminated due to the
finished surface of the edge material.
Manufacturing companies can thus
increase the tool life and efficiency of
their entire machine train and therefore
permanently lower operating costs.
Despite the higher acquisition prices for
the new generation of saw blades, the
use of RIX Formula SPF bi-metal saw
blades provides considerable savings
potential for cutting.
Sägen-Mehring GmbH develops and
manufactures bandsaw blades and saw
blades and the corresponding circular
saws, machine saws, hand saws and
saber saws, as well as metal core drilling
machines and cutting tools for the metal
processing industry and machine tool
trade. The products are sold under the RIX,
Optibohr and Optipress names. In addition,
Sägen-Mehring runs one of the largest
CNC tool grinding shops in Germany for
repairing cutting tools.

RIX Formula SPF helps to
boost cutting performance
IN recent years Thermatool has continued
to play an active part in the metal building
and construction sectors worldwide, gaining
a strong reputation as a leading supplier of
hollow structural section (HSS) HF welding
technology.
The latest range of Thermatool solid-state,
high frequency contact welders have become
central to the manufacture of high quality
engineered structural sections. Engineered
structural sections such as ‘I’, ‘H’, ‘T’ and
other asymmetrical shapes can be welded
continuously on a specially designed HF
welding mill.
Recent advances in steel chemistry with
the advent of advanced high strength steels
(AHSS) and excellent HF weld quality has
increasedthedemandforengineeredstructural
sections. Thermatool has advanced a proven
range of HAZControl Technology welders that
offer custom ‘I’-beam producers excellent weld
quality in materials not previously available.
Thermatool solid-state, high frequency
contact welding technology will precision heat
and forge weld engineered structural sections
at high line speeds with maximum precision,
requiring no secondary re-straightening prior
to shipment. To satisfy a growing market,
Thermatool welding technology has brought
about the opportunity to produce a virtually
HF welded engineered structural sections
unlimited selection of custom beam sections
that offer improved load bearing performance
with a lighter weight product. Today, the
results can be seen in the structure of the
Birds Nest Stadium in Beijing, on board the
latest generation of ocean super-tankers and
at many sports stadiums around the world.
