Bossi Srl – Macchine

WITHIN the research and development
of technologies that are more and more
“customer oriented”, Bossi has recently
designed and supplied a tube manufacturer
with a set of new machines for finishing big
stainless steel welded tubes, to be used in-line
on a tube-mill with TIG welding system.
At this show the company will be aiming
to illustrate a planetary brushing machine
– Mod PL 400/330 – for working diameters
of up to 330mm: the machine in question is
equipped with two brushes and the frame,
which is properly dimensioned, holds the
rotary drum mounted on ball bearings and
is controlled by an inverter: the two brush
opposite spindle groups are positioned on
it, with motorised movement of approaching
and retraction from the tube to be worked.
The weight of 5,100kg and the
dimensioning of the machine allow constant
working, without vibrations.
The simple replacement of brushes is
possible thanks to the wide opening of the
door with vertical sliding.
The machine can be installed on any
tube mill.
Bossi – Macchine Finitura Metalli
operates all over the world, with a leading
position in the manufacture of machines for
metal surface finishing, having more than 40
years of experience in this field. The wide
production range includes machines which
can solve any problem of grinding, satin-
finishing, polishing, deburring, etc of any kind
of ferrous and non-ferrous materials.

Magnetic Analysis Corp
USA 712
MAGNETIC Analysis Corporation (MAC)
has designed a flux leakage system to
inspect cold-worked, ERW straightened
tubes used for automotive suspension
structures and cross members such as
axle housings. These tubular parts contain
proprietary geometric characteristics that
make NDT specifications more difficult due
to variances in the ID of the tube.
MAC’s Rotoflux ® longitudinal flux
leakage rotary was designed to detect
weld defects, internal and external cracks,
slivers, incomplete welds, cold weld and
weld porosity. The Rotoflux is capable
of inspecting material from 60 to 190mm
(2.5" to 7.5") OD, with wall thickness
up to 20mm (0.75"). A small diameter
package is included for precise inspection
of smaller diameters. Mounted on a triple
roll constant centring bench, the system
can test to within an inch of the end of the
tube based on the high quality, smooth
carbon steel surface.
The conductor controls allow the system
to be in line at the end of the production
process while integrating an existing
PLC to control the mechanics. The fully The Mod PL 400/330
automatic final test system is completed
with conveyors that include the EZ drop
feature for the more delicate handling of
material. Accept and reject pockets and
automatic paint markers are also included.
MAC will be exhibiting at Tubotech with
its Brazil-based representative, Polimeter.
