T
wo of the world leaders in wood sanding and
preparation are joining forces with a sales and
manufacturing alliance.
Kunzle & Tasin, the Italian specialist in sanding
tools, and Bona AB, the Swedish sanding and floor
preparation company, agreed a partnership
earlier this year that will see K&T produce
Bona machines in Italy and both companies
selling the combined
ranges worldwide.
Under the alliance,
Kunzle & Tasin will offer
a broader, combined range of
Bona and K&T machines, while Bona
will also sell the full range through its
global organisation.
The partnership means that Bona will
close its production facility in Sweden
and transfer production to Kunzle &
Tasin’s facility in Cinisello Balsamo,
north of Milan.
In a joint statement, Kerstin Lindell,
president and CEO at Bona and Alberto
Biffignandi, president of Biffignandi
SpA (which owns Kunzle & Tasin),
said; “We will have the advantage of using
the joint competences of both companies to
develop machines that satisfy the specific
needs and requirements of our customers, as
our companies have strengths that complement

EDCO has redesigned
its two concrete floor
grinders, with new slide-on
accessories removing the need
to use wooden wedges. The new
holding cases will accept the Dyma-
Serts, PCDyma-Serts and Strip-Serts
grinding accessories for a variety
of different surfaces, with no tools
required to install the accessories.
The system is available on the electric
powered 2EC-NG-1.5 model (pictured)
and the petrol/gasoline 2GC-NG-11H
version.

Blastrac’s new BMP-4000 ride-on sawing and milling machine
is “ideally suited for large milling and sawing applications,
for example road construction and industrial flooring”, says
the company. Launched in April this year, the BMP-444 is
a multifunction unit, with a change of the hydraulic motor
allowing the user to swap the milling and the sawing drum.
In sawing mode the unit can cut and saw
concrete, asphalt and stone to
a depth of up to 60 mm.
Using the milling function,
it can remove 65 mm in several
passes. Working widths are
400 mm (milling) and 380 mm
(sawing) and the unit weighs
1550 kg.
HTC grinders used to improve worn out Swedish roads
Swedish grinding equipment manufacturer HTC
is working with Sweden’s road research body to
determine if its grinders could reduce tyre noise and
rolling resistance on worn out roads.
HTC says a pilot project showed that grinding the
road surface could reduce noise (inside the vehicle
and out) and also lessen the rolling resistance “to a
considerable extent”.
The manufacturer and partners VTI (Swedish
National Road and Transport Research Institute),
Linköping University, the Swedish Transport
Administration, Svevia and Projektengagemang in
Stockholm, are now carrying out a fuller study, which
is expected to be completed in late 2015.
HTC says uneven road surfaces generate
negative effects in the form of noise and increased
rolling resistance, which leads to increased fuel
consumption. Another undesirable effect of worn
road surfaces is the increase in respirable particles.
The pilot project on one of Sweden’s most used
roads, the E4, showed that grinding the road surface
reduced noise by 2.2 dB(A) and reduced the rolling
resistance by 4-7%, resulting in a reduction in fuel
consumption of 2%.
“At HTC, we see the application of HTC’s tried and
tested grinding technology to surfaces other than
stone and concrete floors as very exciting”, says Per
Sandström, HTC’s business area manager, “HTC has
been developing this technology for many years and
we hope this project will confirm what we believe;
our method increases travel comfort as well as
saving both the environment and the taxes spent
on repairing the infrastructure; our roads, in this
instance,”
The company estimates that the grinding method
could lengthen the service life of the road surface by
20 to 50%. Grinding is a relatively fast process and it
can be done either across the entire roadway or just
each other”.
K&T was founded in Italy in 1946 and since
2010 it has been owned by Biffignandi SpA. Bona
AB, located in Malmö, Sweden, is a large, family-
owned company that provides equipment for the
installation, maintenance and renovation of wooden
floors.
along parts of it.
The project has been given the name ‘Via Futura’
and has received a SEK4 million (€0.46 million) grant
from Mistra Innovation, which funds environmental
and sustainability projects linking small and medium
sized companies with academic research bodies.
