BOSSI Srl, Italy, offers a wide production
range that includes machines that can
solve most problems with grinding, satin-
finishing, polishing and deburring of ferrous
and non-ferrous materials – both offline and
inline.
The RSP machines are employed in
the operations of grinding, snagging and
polishing of flat and shaped surfaces made
of steel, stainless steel, aluminium, brass
and all kinds of ferrous and non-ferrous
material. The great flexibility and versatility
of the machine allow the user to obtain
different types of finishing by using many
types of abrasive belts, brushes or mops.
This model is available with different
working capacities (150/200/300/400mm or
500 wide x 150/200/300h).
The finishing lines can be provided with
loading, finishing on one side or two sides
simultaneously, turnover, return conveyor
belt and, at cycle end, unloading and
drainage, which all happens automatically
and needs only a single operator.
Offline and inline solutions for grinding problems
The Multipla UV is a longitudinal brushing
and polishing machine with opposite units.
This type of machine has been designed
for products requiring perfect finishing that
cannot be obtained by traditional centreless
machines. The pieces to be worked are
locked on their ends by tailstocks, and tools,
working longitudinally to the piece axis,
cross the cut of the previous belt working.
Another characteristic of these
machines is that it is possible to work
pieces both with circular and an elliptical,
oval or rectangular section.
The machine is available in different
versions, with two or four brushes, for
pieces with a length of between 300mm
– maximum 3,000 or 6,000mm, diameters
from 14 up to 80mm.
The SF is a new model, recently
introduced by the company that replaces and
changes the concept of classical centreless
machines for working cylindrical surfaces.
It is provided with: easier adjustments;
complete cleaning; working speed up to
20mt/min; reduced overall dimensions; and
longer life time of abrasive belts (20%).
The machine can be supplied with different
driving systems for the pieces to be worked
and automatic systems for piece loading/
unloading.

MTM, together with Atomat, offers specific
turnkey solutions for the production of
structural tubes, either round or hollow
structural sections.
The range of complete tube mills and roll
set includes round tubes from ½" up to 8"
NB and square sections up to 160x160mm.
For shaping thick material, MTM
recommends the use of a profiling section
featuring motorised roughing stands.
Thanks to this technology it is possible to
attain square and rectangular sections with
flat surfaces and sharp corners, complying
with all applicable international standards
for hollow structural sections.
Roll set characteristics are also very
important for an efficient production of
these sections. Both roll design and roll
mechanical properties largely affect not
only the quality of the final product, but also
the wear life of the rolls themselves and
subsequently the overall production costs.
With more than 40 years of experience in
this field, Atomat is able to provide the design
and manufacturing of the most suitable rolls
for this application. The COMBY flying cut
off machine represents the cutting edge
solution for shearing by means of a quick
and effective cold sawing process of heavy
section tubes. Two cutting heads are moved
around the shape by two combined electrical
axes, like in milling-machines.
The ingenious orbital cutting process of
MTM Comby guarantees a reliable and cost
effective cutting method. No gap occurs
between the two blades, thanks to the
rugged structure of the equipment and the
reduced blade dimensions.
The cold saw can operate using either
HSS or TCT blades, which is the case in the
whole range of MTM flying cold saws.
MTM cold saws allow high productivity
and lower running costs, whenever a burr-
free cut is essential.
The partnership Atomat – MTM,
combining its engineering expertise with
an outstanding roll set manufacturing
know-how – says it guarantees an effective
solution to help businesses.
