Weld bead removal for
stainless steel tubes
WITH more than 500 machines sold
around the world, Bossi Srl – Macchine
Finitura Metalli has established itself as
a major producer of belt grinders for
the removal of stainless steel tube
weld beads. The system is installed on
tube mills with TIG and laser welding
systems. Bossi “STP” bead grinders are
the result of technological innovation
and experience gained over many years
in this field.
These machines can work tubes with
outside diameters from 6 to 410mm.
Their main features are ruggedness
and low maintenance demand. They
also have adjustable working pressure,
and adjustable number of oscillations.
The abrasive belt speed is adjustable
by inverter, and oscillation amplitude is
adjustable.
They also have an automatic
centralised greasing system, which
make them widely used bead grinders
by stainless steel tube producers around
the world.
With the exception of some parts
which, for manufacturing reasons,
cannot be made of stainless steel, the
rest of the bead grinder can be made
in this useful metal that, in addition to
lengthening the lifetime of a machine
that is subject to dirt and water, means
that it is possible to avoid the worked
tube from coming into contact with
machine parts of different metal and
getting contaminated. This problem
can give rise to complaints, especially
for tubes that are used in the chemical,
pharmaceutical and food industry.
The bead grinder can also be supplied
with a double control panel allowing the
possibility of installing it on any type of
tube mill in both tube feeding directions.
Bossi can also supply brushing
machines for round, square and rectan-
gular tubes for any size and for all the
speeds in TIG, laser and HF welding
systems.
