Between flat 

cutting and work 

centre, I choose 

lasertube 

The FL250 3D Evolution with a 12 m load and an 8 m 

long Cartesian unloading system is the solution chosen 

by Marelli Aldo to expand and complete its offer in the 

field of third party realization of metallic carpentry. 

An important choice that "winks" to the structural tube 

sector. 

Established in 1979, Marelli Aldo is the 

marriage of professionalism, entrepreneurial 

skills, know-how and experience in the 

field of metal structural 

work. From single 

pieces to small and large production 

series, the company owned by Figino 

Serenza in the province of Como can meet 

any type of sheet metal or metal tube 

machining needs and 

supply a finished product 

of absolute, also 

aesthetic, quality. In its 30 years of business, 

Marelli Aldo has investigated and 

examined the production problems of 

every setting and sector – from simple 

metal fences to more complex structures 

and metal structural work for machine tools 

– and accordingly increased its capabilities 

to meet the urgent and sometimes 

extravagant production needs for interior 

furnishings. These challenges are a real 

proving ground for a third-party processing 

company. Design decisions, often remote 

from real technological possibilities, found 

a ready response in the mastery and 

production and engineering capabilities of 

the company as demonstrated by the futuristic 

reception of a hotel in Rimini and drawing 

tables made for prominent designers. 

Targeted investments policy 

The growth of the company went hand-inhand 

with the continuous and wise process 

of technological 

renewal of the 

machine fleet installed 

in a shed having a surface 

area of 3,200 m². And perhaps it 

was in this setting more than anything 

else in which the entrepreneurship of Aldo 

Marelli emerged brilliantly. Along with his 

son Stefano, he carried forward a policy of 

targeted investments aimed at continuously 

improving the service offered to its customers. 

“The goal of every investment is to 

be able to give something more”, says 

Aldo. “And thereby expand our range of 

action by starting to satisfy even the 

requests we previously could not accept”. 

Proof of this is the industrial thermosetting 

powder painting plant installed in 2001 to 

provide our customers with a truly “finished” 

product. “We set ourselves the goal 

to set up a painting plant that would guarantee 

high-level quality and service, to 

enable customers save time and avoid 

incurring additional costs” explains Marelli. 

“After conducting some analysis we 

believe that the best direction for today 

was a thermosetting powder painting plant, 

suitable for steel, sheet-metal and zinccoated 

parts. Moreover, thanks to the optimal 

quality/price ratio, this type of painting 

is suitable for a multitude of commodity 

sectors, from large-scale facilities to 

interior design and technical lighting

The “smart” 

Cartesian unloading 

system allows you to 

stack single tube 

crops up to 8 m long 

onto pallets in the 

adjacent area of the 

system. 

design and offer optimal resistance characteristics.” 

Therefore targeted investments are important 

but so is farsightedness, as in the 

case of the laser flat cutting system 

installed in early 2004. It provides a work 

space of 2,000 x 4,000 mm and laser 

power of 4,400 W. This allowed Marelli to 

start working right away, even on considerable 

thicknesses. And in doing so it 

distinguished itself on the market 

and rose above the conventional 

“price wars” typically found in thin 

sheet metal. 

“Small items” but mainly large 

sizes 

The same farsightedness and entrepreneurship 

in early 2009 led Marelli to install 

an innovative lasertube, by Tube Tech 

Machinery, which allows it to process tubes 

having a diameter of 15-300 mm, as well 

as bars and profiles with a square section 

as large as 220 x 220 mm and rectangular 

sections as large as 250 x 100 mm. 

Therefore we are talking about a machine, 

the FL 250 3D Evolution, that can work 

“small” but its capability on large size is 

what distinguishes it, further proving the 

intention to stand out on the market in relation 

to those who Aldo prefers to consider, 

because of his philosophy, colleagues and 

not competitors. 

“The time had come to take another step 

forward and make another leap in quality 

for the company”, Marelli continues. 

“Having a 40% increase in turnover as the 

result of introducing the first flat laser, we 

were initially tempted to purchase a 

second system. However we quickly 

decided not to take that route because it 

would have added little in terms of “giving 

customers something new”. We thought 

about purchasing a work centre that would 

allow us to do in-house machining operations 

to remove the chips; however, currently 

we are still outsourcing this operation. 

So there you have it! We had been 

fascinated by the potentialities of applying 

laser technology to the three-dimensional 

cutting of tubes and bars. A lasertube 

would have allowed us to exploit the skills 

we had already acquired by using a laser 

and in so doing significantly expand market 

outlets. More importantly, we could 

pass on several advantages to our customers 

since we could now conceive and 

study the metal structural work in a new 

The Marelli FL 

250 3D Evolution 

is equipped with 

a max. 12 m long 

tube-bundle 

loading system. 

Marelli is able to 

process tubes 

with a diameter 

of 15 up to 300 

mm, but also 

square bars up 

to 220 x 220 mm 

and rectangular 

sections of 250 x

way. Building structures with tubes and 

bars cut in 3-D makes it possible to 

achieve “daps” that used to be unthinkable 

before. They would also be better and optimal 

in terms of performance and resistance. 

It would reduce the need to weld the 

structure which now can simply be “fastened” 

in a few spots. This means having 

even higher precision in the metal structural 

work with higher quality in the machining 

operation at a lower cost because it minimizes 

the worker-machining of residual 

material. 

Unloads tubes as long as 8 m 

in an orderly fashion 

The FL 250 3D Evolution installed at Marelli 

Aldo is the concrete expression of the 

capabilities of Tube Tech Machinery to personalize 

its systems according to specific 

production needs. “We chose this plant 

mainly for the purpose of the machining of 

medium large parts, though in the initial 

phase small diameters are more prevalent” 

Marelli explains. “It is our intent to emerge 

in the field of structural tubes and this is 

why we opted for a versatile and flexible 

plant, having a CO2 laser source of 3,200 

W. There is no doubt that we stand out 

from others because of the configuration 

chosen, because the machine has a 12 m 

tube-bundle loading system, a third 

spindle that makes it possible to pick up 

and machine even the last crop while 

another tube is being loaded. Moreover 

there is an innovative Cartesian system 

that unloads “intelligently” in the adjacent 

area for the stacking of each individual 

tube crop, up to 8 m long, onto pallets. 

This aspect is vital because it allows you to 

unload the tubes in an orderly fashion and 

find them practically ready for packing and 

shipping without having to go over them 

one by one. This translates to wasting less 

time, increasing productivity and lower 

processing costs which becomes a direct 

benefit to the final customer. This advantage 

is even more significant when handling 

large heavy tubes”. 



The lasertube has a revolutionized the way Kägi 

manages its work which increasingly uses lasers 

even for simply cutting tubes or sheets to size. 

3D CUTTING 

Semi-finished and finished tub 

Kägi is a Swiss company with a long history of selling tubes that – contrary to what one might think 

due to its over 100 years of company history – is an eminently dynamic business that is evolving all 

time. Several years ago it took the decision to reinvent itself and go beyond being merely a tube retailer 

to becoming an actual partner who could provide a service to its customers by finishing finished 

tubes according to specific requirements. 

K 

of the Brescia company”, We currently produce 

three plant sizes: the FL 250, the FL chining the piece which is such an expen- 

ically. It will no longer be required to re-ma- 

400 and the FL 600. The FL 400 3D chosen sive step of processing because it requires 

by Kägi is the intermediate size. A size that suitable locking equipment and machinery 

allows it to approach the small-tube market, 

i.e. approximately 40 mm, as well as less time is needed than in the past”. 

(different for each article). Moreover much 

large diameters of up to 406 mm, with any 

type of section: round, square, oval, modelled 

or an open profile that can be inscribed 

in the maximum diameter according to the 

initial intentions of Kägi. We are one of the 

few manufacturers who offer such a wide 

range of machinable diameters”. 

ägi has always worked in the sale and 

distribution of metal tubes and profiles. 

Being equipped only with conventional cutting 

lines (circular saws) for cropping and 

cutting tubes to the requested sizes – solutions 

that recluded to perform the finishing 

operations on the tubes – the 

company long ago intuited the possibility 

of being able to better 

“serve" its customers by supplying 

tubes that were already 

finished with notches and anything else required 

to improve and facilitate their use. 

Kägi is very familiar with the machining of 

tubes and therefore knows that it requires 

several specializations. The sectors and settings 

where it is used are vast and extremely 

diversified. This awareness suggested 

laser cutting as the most suitable technology 

for this purpose. So it found in the FL 400 

3D system made by Tube Tech Machinery 

the ideal solution for its needs. 

A fundamental aspect that characterizes the 

strategic move made by Kägi was its willingness 

to process a certain size of tubes, 

while thinking about the possibilities of processing 

medium-to-large diameters to distinguish 

itself from to its competitors already 

present on the market. This is why they chose 

an “intermediate” plant from the Tube Tech 

Machinery range. “Though still a work in 

progress, the FL 800 will bring lasertube performance 

up to levels never reached in the 

past", says Alessio Cadei, Sales Manager 

More rapid and higher precision 

assemblies 

“Kägi found in our technology a basic strong 

point”, states Cadei. “The use of the 3D cutting 

head mounted by Tube Tech Machinery 

on all of its machine models, even the smallest, 

demonstrates this. Our “3D” is not an 

optional. In fact the machine is equipped 

right from the start with this type of head. I 

could almost say that the “2D” is the optional 

in this situation. Upstream of all it is an 

important awareness. The world of tubes is 

evolving and companies who embrace the 

lasertube will not be making an anachronistic 

decision but will be going beyond the 

immediate situation at hand. Bear in mind 

that tomorrow, companies might have the 

need to make bevels, partial cuts and even 

other machining operations that the 3D head 

will allow them to make safely and econom- 

One of the basic strategic elements in the 

continuous growth of the lasertube is precisely 

the possibility to make complex structures 

in the simplest possible manner thanks 

to the daps you can obtain by fully exploiting 

the potentialities of laser cutting. “The 

possibility to use the 3D cutting head”, adds 

Cadei, “allows the designer and engineer 

to come up with solutions that until now have 

been unconceivable, and that bring huge 

advantages in terms of assembly. 

Assemblies are quicker and more precise 

and, furthermore, sturdier and more economical”. 



Perfect alignment of tube under head 

The 3D head was certainly one of the 

aspects to which Kägi gave priority. 

Another decisive factor was the machine 

configuration with four mobile spindles that 

make it possible to “mask” all the dead 

times associated with handling the tube 

and as such they do not affect the 

production cycle. As the cutting operations 

are carried out the tube goes from spindle 

1 to spindle 2 and then to 3 and 4 and 

while the last machining operation of the 

tube end segment is being finished, the 

new tube can be loaded and prepared for 

cutting; the machine is immediately ready 

to cut without having to wait any time at all 

for unloading. 

“The technology of the four spindles 

contains multiple functionalities to avoid 

mechanical problems, or any kind of 

problem for that matter, especially in the 

handling of tubes with large diameters and 

thicknesses that, by their very nature, are 

never perfectly straight” explains Cadei. 

“Often they are subject to “bends” that 

must be managed properly to avoid 

damaging machine parts. This is why 

spindles have self-centering and selfloading 

systems designed to compensate 

for the geometric errors of the tubes and at 

the same time ensure the perfect 

alignment of the tube under the cutting 

twice as fast as the typical speeds for 

machining tubes of these dimensions. 

Personalized Lay-out 

Another aspect that should not be 

overlooked, and that in the case of Kägi 

was given extra care, was the 

personalization of the entire plant, even in 

terms of its layout. The optimal 

management of the handling of tubes, 

whether rough or cut, is only apparently 

secondary but it is essential when we are 

talking about tubes having lengths up to 14 

m that weigh a few tons and are extremely 

cumbersome to move around the shed. We 

therefore established with Kägi the ideal 

flow for rational machining of the tubes; 

this means that an incredible amount of 

care was given to the starting position of 

the rough tube and where it is more 

Finished semi-manufactured parts, 

even those with a small diameter 

The lasertube is becoming an increasingly 

strategic choice for companies who 

process sheets but want to expand their 

business to include similar sectors as well 

as for companies like Kägi who want to 

supply finished products in addition to 

cutting tubes to size. Therefore the 

decision to invest in an intermediate 

machine was the right decision because it 

allowed the Swiss company to position 

itself on a market segment that has not yet 

been covered, i.e. that of large tubes. And 

it also allowed them to see and experience 

the potentialities it provides for sectors that 

use small tubes. 

Currently, in spite of the number of 

competitors, the largest volume of work is 

for medium dimensions and medium-small 

dimensions. This is why Kägi, after 

purchasing the FL 400 3D, wanted to add 

a second lasertube and has even started 

talking about a third machine. “This would 

be an FL 250 3D and the clear goal would 

be to supply customers who need very 

small tube diameters, even smaller than 20 

mm, up to a maximum diameter of 300 mm 

with lengths of 8,500 mm” explains Cadei 

satisfied. “Consequently they chose a 

slightly smaller type of machine but again 

The four-spindle

functions that are 

designed to avoid 

mechanical 

problems, or any 

type of problem for 

that matter,

nature, are never 

perfectly straight. 

e according to specifications 

head. The tube might be crooked but the 

machine can manage it without damaging 

itself and, more importantly, while 

maintaining the precision of the cut. The 

spindles can function independently or can 

be connected as a gantry function”. 

Summing up the three basic aspects in 

Kägi's decision, we need to firstly mention 

the possibility of covering an extremely 

wide range of machining operations, as the 

well-established possibility of making 3D 

cuts and, most importantly, the plant 

productivity and flexibility because in all 

handling operations of tubes while the 

machine is running, productivity becomes 

truly unrivalled. The increased productivity 

is also associated with the increased basic 

speed of the axes that move the machine. 

In fact we are talking about a machine 

equipped with linear motors that run on the 

main axes at 100 m/min, in other words 

convenient to “come out” with the 

processed tube to achieve an appropriate 

flow to the production cycle and ideal for 

positioning of the plant “utilities” (laser 

source, electrical board, etc.) that have 

been arranged in such a way as to not 

hinder the work process. “Kägi wanted a 

raised platform on which to position 

electrical boards, the suction plant and the 

laser source so that the space on the 

ground could be dedicated to other 

components of the plant” specifies Cadei. 

“We are talking about a total length of over 

40 m by 16 m, with a 14 m long “loading” 

and “unloading” stretch. 

Optimal suction of fumes 

The plant installed by Kägi respects the 

work environment and the workers. The 

automated handling of tubes significantly 

reduces the risks to human safety, as well 

as the cutting fumes suction system which 

is always present inside the tubes. There 

are two suction systems, one on the right 

edge and the other on the left. This 

guarantees optimal suction of the fumes 

produced by the cutting even during the 

final assembly of the last tube crop. A 

suction device alone would not make this 

possible and would significantly pollute the 

air in the workshop. Tube Tech Machinery 

ensures maximum suction in a work 

situation, with noticeably positive effects on 

work safety and worker health. 

did not want to give into the “laws of the 

marketplace” that simply require the 

classic machine for 2D tubes having a 

diameter of 6 m. In these cases the 8,5 m 

3D tube with diameter up to 300 mm is 

machined in a flexible way, closed and 

opened profiles thanks to the chain 

operated front loading system. This new 

machine manages tubes having a linear 

weight of 45 kg/m, in other words its 

performance is decidedly high”. As we 

have seen, the lasertube has 

revolutionized Kägi's work management in 

a way that increasingly exploits the laser 

even for simple operations of cutting to 

size. The fact of also being able to use the 

lasertube for cropping operations, and 

program them easily and rapidly, certainly 

represents an additional opportunity 

though Kägi's primary reason for installing 

the Tube Tech system was to supply 

finished tubular semi-manufactured 

products. 

The 3-D cutting head 

was one of the 

decisive factors for 

choosing the FL 400 

and 250 cutting 

systems. 

The FL 400 3D 

cutting system is 

installed at the Kägi 

factory. 


[ SOLUTIONS ] 

Tube Tech Machinery has presented the new TS 5.12, the latest sheet metal welding 

plant developed by the company after its fortunate experiences with the 

TS4.20. The machine is capable of trimming and welding sheet metal with nominal 

dimensions of up to 12,000 x 2,500 mm and thicknesses ranging from 1 up to 8 

mm to obtain finished sheets having a large-size, with maximum dimensions of 

12,000 x 5,000 mm. This is a solution that makes it possible to think of welding different 

thicknesses of sheets to obtain “Tailored Blanks”. 

Tailored Blanks … 

… no problem 

T 

he TS 5.12 has a remarkable degree of automation 

that, starting with the rough sheet fed 

manually, allows you to align and centre the 

sheet by alternating longitudinal and transversal 

movements on rollers provided 

with a safety clutch. After centering 

the first sheet, it is locked with an automatic 

hydraulic blank holder stop and 

then trimmed using the laser cutting head. 

Simultaneously with the trimming of the first 

sheet, the machine brings the next sheet to 

the proper position, aligns it and centres it 

until the final trimming phase. After trimming 

the two adjacent edges of both sheets, the 

machine brings them closer to each other and 

welds the edges continuously with the laser 

head and without deposit metal. A US welding 

control system is provided during the entire 

process. These phases can be repeated 

in automatic mode until the formation of a 

sheet having maximum dimensions of 12,000 

x 5,000 mm. 

A fibre laser of 4 kW 

One of the most important new features of the 

TS 5.12 is certainly the use of the fibre laser. 

For the first time, Tube Tech Machinery is ready 

to use a fibre laser resonator (4 kW) made 

by IPG Photonics with the certainty that after 

conducting in-depth trials and multiple tests, 

is today the best solution for welding without 

deposit metal. 

Another point of interest of this new TS 5.12 

is the possibility to be able to start with 

sheets made from coils, appropriately prepared. 

This reduces costs of raw materials 

The TS 5.12 cutting and welding system will be 

ready for the first tests and inspection trials at the 

beginning of 2010. 

which benefit the cost of the final product. 

Moreover the possibility to make metal 

sheets to size (Tailored Blanks) allows them 

to “build” a metal sheet with variable thicknesses 

to reduce the weight of the sheet and 

provide the resistance capacities required. 

This factor also contributes significantly to 

cost reduction while improving the quality of 

the product. 

The machine will be ready for the inspection 

as early as January 2010. 

XXL LASER WELDING 

Producing large sizes from small standard 

sheets is the specialty of the 

transformation technique used by 

Göcke in Ahaus. Its TS 4.20 laser plant 

made by Tube Tech Machinery automatically 

welds sizes of up to 4 m 

wide and 20 m long. The beads are 

extremely thin and do not shrink. 

The TS 4.20 welds small sheets to 

make large-sized sheets; they purchase 

the sheet sizes found in regular 

stores – small, medium and large 

– and weld them to make them into 

small plates that can reach the abovementioned 

dimensions. Thanks to the 

laser technique, even very thin sheets 

can be joined without deforming them 

and this is a great advantage. The 

plant processes sheets that are 1,5 – 

8 mm thick. 

“We keep an individual solution ready 

for every request”, says Jörg Göcke, 

the director and son of the company's 

founder. “Since we are specialized 

in special productions, we offer 

the best possibilities for rapidly and 

impeccably welding the products according 

to size or unusual dimensions. 

One of our distinctive strong points 

is the large size which can be as much 

as 25 m long. 

These pieces are used in building 

bridges, vehicles or open air excavations”. 

So Göcke in Ahaus produces 

machined parts for the mining of lignite 

or half-octagonal shells for the 

construction of current or electricity 

poles for the procurement of energy. 

Another important application for 

Göcke is the construction of wagons 

for the metro trains, urban rail trains 

and regional railways; for the wagons 

of local traffic it produces whole 

sheets of stainless steel for the lateral 

walls that are solid, lightweight 

and trimmed. 

Growth has facilitated the decision 

Offering innovative solutions in all 

sizes means having to continuously 

update production. “We work with a 

modern fleet of machinery that is continuously 

reorganized and renovated 

in accordance with the latest technical 

standards,” says Göcke. “Our 

ongoing aim is to be increasingly innovative”. 

So, the growing demand 

for large welded sizes has confronted 

us with a choice: do we outsource 

a certain volume of the orders or keep 

them in-house and invest in a new 

laser welding plant? 

“The decision to install the TS 4.20 

was essentially the classic “Make or 

buy" decision. It was up to us to decide: 

should we outsource this work 

or do we want to provide this production 

in-house according to our high 

quality standards? The volume of orders 

increased so much that over time 

we decided to invest in this TS 4.20 

automatic laser welding plant. 

Another reason for our decision was 

the desire to embark on new ventures”.

New 

The cutting operations 

are also automatic 

To complete the range of machines that cut and weld metal sheets, 

Tube Tech Machinery is developing new solutions that also integrate 

the laser cutting technology for the realization of finished pieces. In 

addition to the TS4.20 and TS5.12 lines, we are currently designing a 

solution that allows the preparation by welding the large sheet and later, 

on the same machine, subjecting it to all the laser cutting operations 

-- completely automatic -- to produce the finished product. These 

are usually specific customized plants, therefore designed to solve 

very specific problems. In particular this type of machinery has applications 

for situations where huge sizes need to be made, e.g. the edges 

of train wagons and metro cars. The goal of the new plant is to 

weld sheets using a laser head without deposit material and therefore 

to make the cuts that will constitute the windows and doors of 

the aforesaid wagons in automatic mode. One of the main advantages, 

besides the notable speed of the process, it is the remarkable 

savings in the handling of the sheet that in these cases can be as large 

as 4,000 x 25,000 mm for making double-decker carriages. The 

machine will be able to start with standard sized rough sheets and 

pre-assemble the large size and cut it. It will then use an integrated 

handler to unload the sheet directly from the machine into the position 

stipulated by the customer. The new plant will also have a system 

for automatically unloading the offcuts which are large since we are 

dealing with wagon windows (approximately 1,500 x 1,000 mm): 

these offcuts will automatically be stacked on pallets and then made 

easily available to be reused on other laser cutting machines.

FL 800 moves the challenge ... 

urrently Tube Tech Machinery already has the broadest 

Cand most complete range of lasertube plants and 

produces three different machine sizes: FL 250, FL 400 

and FL 600. However the new FL800 is currently being created, 

and is a solution that will raise the bar even higher in terms of 

maximum machinable diameter, the real “challenge” for 

lasertube manufacturers. In addition to being able to process 

large diameter tubes, this new machine will embrace a fresh 

concept for moving them. In fact the plant will have air portals for 

loading and unloading and therefore will enable the precise and 

rapid management of heavy tubes. The portals will be managed 

in a simple and intuitive manner by the CNC and 

will not require a change in set-up when 

changing the type of tubes. 

“We can also produce customized 

metal plates”, Göcke continues, 

“the so-called Tailored Blanks, to 

make a large sized sheet in various 

thicknesses and of different 

materials or types of steel. An important 

advantage of TS 4.20 is the 

automatic control of the welding 

bead. Here the machine controls 

the three values of pliability, temperature 

and luminosity of the 

product. From this we can figure 

out the quality of the welding bead. 

As long as these three values stay 

within the established tolerance 

field, the welding bead is considered 

good. If any defects occur, 

the plant continues to weld its initial 

program until the end. Then 

there is a visual control by the 

welding control unit. If the defects 

are found, such as pores or inclusions, 

the entire joining process 

is repeated, in other words the 

weld is cut and welded again. 

Synergy 

The visit of Alessio Cadei, the Sales Director 

of Tube Tech Machinery at the Trumpf location 

in Ditzingen confirmed and further strengthened 

the close collaboration between the 

two companies. The meeting made clear the

German company with whom it was reinforced 

the strong partnership so that it is not unilateral, 

i.e. supplier-customer but it makes possible 

to engender more effective synergies 

developed jointly.

IN PIACENZATO TALK 

ABOUT Lasers and 

Aluminium 

“The welding of aluminium: new prospects offered by modern 

laser technology”. This was the theme dealt with at 

the opening discussion at EXPOlaser 2009 (19 - 21 

November) with the contribution of Tube Tech Machinery 

and IPG Photonics and major Italian universities such as 

the Milan Polytechnic and the University of Brescia. Welding 

aluminium with laser technology is a topical issue that is 

spreading widely through the world of light alloys, especially 

in light of the advent of innovative fibre laser resonators. 

Performance and operative flexibility are wedded 

with premium mechanical characteristics making possible 

the application of this technology even in fields that till 

now have been predominated by conventional welding 

methods. This is why the afternoon Conference of Thursday 

19 November is something you will not want to miss.

Tube Tech Machinery will soon blow out the ten candles. It is celebrating 

its tenth anniversary during an extremely difficult and problematic macroeconomic 

context in which so many companies are floundering. 

Nonetheless T.T.M. increased its turnover by 5% in 2008 and the forecast for 

2009 allows to confirm the same turnover as the previous year. T.T.M. recently assembled 

a “Tailor made” brochure showing its range of machinery and plants, 

including the latest inventions. I really like the idea of “the smallest company with 

the broadest range of laser machines for processing tubes”. 

In this market segment we offer solutions that can machine tubes with diameters 

of 15 mm and even reach 800 mm, all using the 3-D cut. In these plants we have 

introduced (and once again, we are proud to be the first) “intelligent” unloading 

portals. This solution is achieved by using controlled axes and inventions that 

can generate significant increases in 

productivity estimated at around 20 - 

30%. All of this is done in absolute safety, 

bringing an improvement to the work environment which, as you know, is 

now an added value as well as a regulatory obligation. In December we will present 

the new TS 5.12, the plant for cutting and welding different sizes of sheet 

metal, whether it is carbon steel or stainless steel, with a work field of up to 5000 

x 12,000 mm. The generator will be Fibre Laser 5000 W made by IPG Photonics. 

We will concretely have a way to verify the performance and characteristics of 

the laser at a high brilliance level. This technology, highly anticipated on a market 

that has high expectations, will be tested by T.T.M. and compared with the CO 2 

laser. We believe it will represent an enormous step forward in the world of applications, 

even though, like all things that must be tested in all possible situations. 

Therefore, in spite of these difficult years for the economy, in 2008 and especially 

2009, T.T.M. continued to persevere undaunted in its process of growth and research 

of new applications. 

A constant growth
