OTO Mills SpA has been designing,

manufacturing and installing complete

systems for the production of tubes and/or

welded sections for around 30 years. The

company has a 70% share of the western

market for systems up to 8" and it is now

extending its production range up to 24".

The steady growth achieved by Oto Mills

SpA through all these years in a somewhat

challenging sector has been made possible

largely thanks to its ability to invest in its

expertise and bring excellent products to

market that meet the increasingly diverse

requirements of its customers. The key to

the success of Oto Mills SpA has therefore

been the ability to differentiate itself from its

direct competitors, by always endeavouring

to stay one step ahead, even in fields that are

constantly changing, like safety.

The new Machinery Directive, 2006/42/

EC, raises the bar in terms of machine

design and construction quality for ever

greater safety, while extending the

definition of a “machine” and thus driving

all manufacturers of tube and/or welded

section production systems to adopt the CE

marking and to comply with the applicable

safety requirements. Oto Mills SpA has

embraced this challenge too, making

safety a crucial component of its machines

that it builds into the process right from

the design stage, while promoting the

training and continuous development of

its own technical staff on the EN technical

standards.

Given that safety measures are a joint

effort between the designer and the user,

those measures that can be integrated in

at the design stage are to be preferred and

are generally more effective than those

implemented only later by the user. That is

why each of its designers is motivated and

engaged to develop the awareness that

manufacturing in safety must be possible,

and that if a hazard cannot be eliminated

then it must certainly be reduced: solutions

must be found at the design stage, as if left

until later they may become less effective

and too complex.

It is only this firm belief that enables Oto

Mills SpA to achieve the expected results,

which certainly include the need to ensure

that the machines possess the required

operating functionality and meet production

standards, while minimising the level of

risk for operators. Its increasingly powerful

manufacturing automation facilities help

increase productivity while ensuring safety

during the production process. The weak

link, however, remains the adjustment and

control process which, like maintenance,

requires very careful examination. Only

by putting these kinds of task under the

microscope, together with the willingness

to redesign or modify the parts that give

rise to excessive risks, can better and even

more significant results be achieved.

That is why Oto Mills SpA now makes

risk analysis the springboard for every

new design. The mechanical hazards

associated with the machine have been

addressed as a priority, and the vast

majority of the machines making up Oto

Mills’ systems may now be considered fully

safe, thanks to the continual involvement

of the various technical disciplines (from

electrotechnicians to mechanics) and a

team working approach.

Many important and significant results

have been achieved, and others are in the

pipeline, as the health and safety of its

machine operators is and will always be

an essential component, no matter what,

for Oto Mills SpA in its constant pursuit of

excellence.

CLOMEA is a manufacturer of bending

machines for metal profiles. Planning and

production, completely developed in-house,

relates to a range of sixty models of

bending machine with various powers and

technological solutions, up to CNC models.

Rollers and equipment are also an

integral part of CLOMEA’s production,

backed by years of experience and high-

level industry know-how.

The target of improving the performance

of machinery and flexibility of application in

various fields should not affect the simplicity

of use. In response to these needs and

following suggestions received from

customers, the company developed the

new numerical control CNW333, applicable

to all of its hydraulic bending machines.

The CNW333 is developed on the Windows

XP operating system, can operate in single

and multi-run, and is applied to hydraulic

machines both with two-speed rotation motor

as standard and with speed regulator, which

allows operation of four processing axes with

automatic speed calculation.

In addition to the functions already

present in the other versions, it provides
