Development of saw blade
technology
TENRYU Saw Mfg Co, a producer of
tungsten carbide/cermet tipped circular
saw blades for various materials,
celebrated its 100
th
anniversary in 2013.
The company has followed the market
and continuously developed products to
satisfy growing demand for smooth and
accurate cutting to avoid machining
of cut surface, increased life time,
and for short cutting times.
Tenryu followed the development
of cutting machines and gave
input for their improvement and
application to cut materials which
in the past could not be cut by this
method, such as Duplex and Super
Duplex, high alloyed steel and
titanium.
Development of tooth materials,
tooth shapes, material of saw
body and coatings, together with
continuous adaptation of the latest
production technologies, made it
possible to use throwaway type blades
economically, up to saw blade sizes
of approximately 1m. These products
not only offer a constant life time, but
allow stable calculation for running
production and future investments.
Another objective of in-house R&D is
to provide very thin blades to generate
saving of material and energy, and
reduce machine wear – important
concerns, given the continued shortage
of raw material and increasing cost of
energy.
The availability of Tenryu products
is secured by expansion of sales
networks and stocks around the
world by subsidiaries in Japan,
Thailand, China, India, USA, Mexico
and Germany, and cooperation in
many other countries.

Hydrostatic gravity filtration
AGR Filtri’s gravity filtration system with
high hydrostatic head type HFS is used
to remove metal particles produced
by industrial processes such as HF
welded tube production lines and profile
mills and found suspended in liquid
lubrocoolants.
The high level of liquid held by the
filtering bag and the high pressure
exerted by the liquid increases efficiency
of the filtering fabric. Compared with
traditional flat bed gravity filtration
systems, with the same flow rate of liquid
to be filtered, the size of the HFS filter
is smaller and therefore higher degrees
of filtration are reached, reducing
consumption of the filtering fabric.
The standard production of HFS
hydrostatic strainers is available for
flow rates up to 4,000l/min. All of AGR’s
hydrostatic strainers can be equipped,
upon request, with a magnetic filter in
order to submit the liquid to be filtered to
a preliminary filtration treatment.
The HFSM series hydrostatic filtration
systems, combined with magnetic filters,
are used when there is a high content of
ferrous particles suspended in the liquid
to be treated. Magnetic filters are able
to eliminate a large part of the pollutant
magnetic particles before they reach
the filtering bag of the hydrostatic filter,
allowing a reduction in the clogging and
feeding cycles of the filtering fabric.

New fin press
BURR Oak Tool Inc has launched the
FP-400 fin production line. A 45-ton,
straight side style press, the FP-400
produces fins with design elements that
lead to longer tool life.
The increased tonnage over the Oak
FP-1 press allows for a wider variety
of fin materials and more intricate
die tooling patterns. A new extended
bolster increases flexibility, and the
interior of the die is easily reached for
tooling inspection and maintenance.
For over 65 years Burr Oak Tool Inc
has designed customised production
machinery for the heat transfer and tube
processing industries. Oak machines
are installed in over 70 countries.
