Tradition
is COMMITMENt —
and spurs us on!
Many of us tend to reflect on the past, with a misty
look in our eyes, when celebrating a milestone birthday. We at TRUMPF prefer to see the celebration of
the 90th anniversary of the company’s founding as
an incentive to take a bold step forward — and are
looking ahead to the next decade of innovations connected with lasers and sheet metal processing. We intend to use the experience accumulated over the past
90 years to depart from well-trodden paths and to
question the status quo. We have made the CO2 laser
significantly more efficient and introduced BrightLine
fiber as a stepping stone for our solid-state lasers into
the world of heavy-gauge sheet metal (page 15). These
two resonator concepts have come together on a par
with each other thanks to this technological milestone. Our customers’ decisions are sure to be the
right ones, regardless of whether they prefer solidstate or CO2 lasers.
I am also impressed when I look at our customers in the USA. The Lamson & Goodnow company
(page 8), a cutlery manufacturer rich in tradition, cuts
and marks its quality products with our machinery,
with lasers made by TRUMPF. And TRUMPF customers have been playing a highly visible role in the construction of New York City’s latest landmark, the One
World Trade Center (page 19). TRUMPF machinery
was used to laser-cut, punch, and bend the stainless
steel façade elements and the beacon, 18 meters tall.
These exemplary success stories show that we are
right up at the front in international markets. And
that motivates us. We want to continue helping our
customers always to be one step ahead, all along
the line, and always to get the best solution from a
single source. That is irrespective of whether they
manufacture tradition-steeped products or embellish
towering landmarks.

Worthwhile investments
Marlin Steel recognized for its forward-looking strategy
This year, there is every reason for celebration
at Marlin Steel Wire Products in Baltimore,
Maryland. The Precision Metalforming Association Educational Foundation recognized this U.S. firm for its investments in new
technology and in training for the 30 employees. The Metalforming Pioneer Award
was also granted for the most recent expansion of the company’s line. This enterprise
invested 3.5 million U.S. dollars in new machines, among which were a TruLaser 1030,
a TruBend 3120, and a TruPunch 2020.
The Marlin Steel team is proud of its
work — and of the new machines.
In business for 45 years, Marlin Steel manufactures material handling containers for
the aerospace, automotive and pharmaceutical industries. Until recently, almost all were
made of steel wire. Using the new equipment on the shop floor, the company is now
manufacturing sheet metal components itself, opening up new design options for the
containers.
“True to our motto — ‘Quality Engineering
Quick’ — we want to get products to the customer as fast as possible,” is the explanation
offered by CEO Drew Greenblatt. “That’s
why we launched our own sheet metal fabrication operations — to avoid having to wait
for suppliers.” Those investments came at just
the right time. The sheet metal containers
are the perfect complement to the range of
wire products made by Marlin Steel and in
the meantime account for one-third of revenues, which last year reached a record level
of five million U.S. dollars.

PANORAMA
From a machine shop with five employees
to a corporate group active around the
world: 90 years of TRUMPF.
A double birthday
TRUMPF celebrates its 90th and the Swiss subsidiary its 50th anniversary
TRUMPF is celebrating two anniversaries this year. The Swiss subsidiary in Baar was founded 50 years ago — and TRUMPF has now been
in business for 90 years. The corporate chronicles began on September
15, 1923, when Christian Trumpf acquired a majority shareholding in
Julius Geiger GmbH of Stuttgart. The machine shop with its five employees was quick to grow, expanded its product line, and was soon to
offer an extensive range of electrical and pneumatic tools. After WW II,
the company started to manufacture stationary machines for sheet
metal processing.
In 1950, Berthold Leibinger joined the firm as an apprentice. Later he earned his diploma as a mechanical
engineer and in 1961 assumed a position as manager
of the engineering department. Just five years later,
he became chief technical officer. Then, in 1979,
TRUMPF combined sheet metal processing and laser
technology with its TRUMATIC 180 LASERPRESS
and presented its very first combined punch and laser

machine. Over the following years, the company developed lasers and
machine tools even further. Towards the end of 2005, Nicola LeibingerKammüller succeeded her father as president of the TRUMPF GmbH +
Co. KG. She continues to steer the company, which in the meantime
employs about 9,900.
TRUMPF took its first step into foreign fields by founding a subsidiary in Switzerland in 1963. The original employees started business in
a four-and-a-half-room apartment in Zug. Much has happened
since then. Initially a pure sales office, the Swiss employees
moved to Baar in 1978, where they also set up a production facility. There followed several expansion projects as well as the implementation of an R&D department and the introduction of the SYNCHRO
system. Today, a staff of 250 is at work in Baar.

Researcher on trends and the future
> How does one forecast the future?
> Which trends will impact the industry in the next ten years?
Futurology is a profound science of systems and involves
building complex process models. Even though you can’t
forecast everything, a lot actually can be predicted. For
instance, certain socio-cultural systems can definitely be
forecast well in advance, since human behavior provides
more constants than you might normally believe. In other
fields, it is possible to work with probability — when
dealing with economic or political questions, for example.
Nowadays we know much more about the future of
technological processes, too. It is hardly wild speculation.
One example is the transition from GloBALization to GloCALization. Jobs that have been
outsourced to low-wage countries over recent years will be returning to Europe and
the U.S. It will become more lucrative to produce locally because — in this energy-critical day
and age — the cost of energy needed to transport merchandise is going to soar. Wages in
emerging countries are also going to skyrocket. In the next few years, these countries will be
setting up infrastructures similar to the ones we have developed in the West in the last two
centuries — a gigantic market. For us, regional economic cycles and multi-regional networks
are going to be ever more important. The motto will be: “From offshoring to nearshoring”.

Modern
heirlooms
Are high tech and tradition mutually exclusive? “Certainly not!” says Brian Hayes.
After all, that is the basis of American cutlery manufacturer Lamson & Goodnow’s success.
If you ask Brian Hayes how traditional values can be combined with a
modern corporate strategy, he flashes a roguish smile. “Really there’s no
difference. Our present strategy is also based on traditional values,” he
says. “Our goal remains the same: We want to produce the best quality — hand-finished goods at fair prices, that the consumer will have as an heirloom piece. The tradition lives on with each knife that is sold.” Hayes
knows what he is talking about. The history of the American knife and
cutlery manufacturer Lamson & Goodnow, which he has headed as president since 2009, covers an impressive 176 years. And the combination
of traditional and modern manufacturing makes it a success story right
up to the present day.
An energy source dating back to 1837
Everyone visiting the company in Shelburne Falls, Massachusetts, sees
that tradition can be kept very much alive. Departing Interstate 91, the
route follows the Mohawk Trail through the forests of New England.
Then you arrive, at the headquarters of Lamson &
Goodnow directly on the Deerfield River, to a
welcome from retriever Sadie Rose — and are
transported back into the 19th century. Even today, knives and cutlery leave the same production shops as when the company was founded in
1837. “The forefathers of our company had tremendous foresight and originally used the power
of the Deerfield river to run our equipment. The
water was diverted right through the center of our factory and under
the buildings to power the water wheels,” as Hayes explains the choice
of location both then and now. The company has remained true to that
principle, merely replacing the wooden water wheel with a hydro power
plant in 1910. That plant still provides the electric power required today.
A glance into the production shop provides the proof. There you see
machines which have over a hundred years of service behind them. They
are used, for example, to grind the knives. The old equipment is tried and
tested, and easy to operate, says Hayes. “It is important for me to remember our heritage, focus on fine tuning our hi-tech aspect while maintaining our hand-made products,” he emphasizes. “We work with modern lasers, robots and CNC grinders, while descendants of Lamson craftsmen
still assemble and finish all our products by hand.”
Traditional manufacturing plus laser
Reflecting that mixture, the TruLaser 1030 fiber 2D laser cutting machine
stands out among the traditional machinery and systems — nevertheless
fitting in perfectly with the manufacturing structure. “We use the solidstate laser machine for all the parts we cut: all the cutlery contours and
the cutouts where we subsequently fasten the
handles. The batch sizes mostly range between
10 and 10,000 pieces,” the company’s president
explains. “We process stainless steel, aluminum, brass, copper and titanium.” Until the
first laser cutting machine from TRUMPF, a
TruLaser 2525, was purchased in 1999,
Lamson stamped out the parts. Hayes therefore
regards the adoption of laser technology as one
of the most important milestones in the company’s development. “That
gave us a great competitive advantage and we were able to modify the
geometries simply, rapidly and cheaply — even for small series.” →
“The tradition
lives on with each
knife that is sold.”

strategY
But in August 2011, the Deerfield River burst its banks and
destroyed large parts of the production facilities — including the TruLaser 2525. Lamson & Goodnow had to close
down for several months. Hayes was all the happier when
he was able to restart production with one of the first
TruLaser 1030 fiber machines manufactured by TRUMPF.
The high speed and flexibility tipped the scales in favor of
the solid-state laser. “We mainly cut steel between between
0.8 and five millimeters in thickness. That is where the machine excels. In addition, we now have the capability to cut
non-ferrous metals with the laser, too.”
Traditional craftsmanship
Around 40 steps are necessary to turn a steel blank into a
knife ready for dispatch: from cutting, grinding and inspecting the blade, through sizing and buffing the wooden handle, to fitting the parts together, deburring, polishing and
inspecting each individual knife. Right at the end, Lamson
& Goodnow engraves the company logo on the blade using
a TruMark Station 5000. Many of the steps on the way to the
high quality knife are still performed by hand. “The precision cutting, heat treatment, grinding, polishing and handle
making are done by machines,” Hayes explains. “All other
functions are done by hand.” That makes him and his team
particularly proud — and gives Lamson a competitive edge
over its global competition. “While many items look similar at arm’s length, we like to think that it is worth putting
a bit more care and attention into the details, fit, and finish of each item,” he emphasizes. “There are certain things
that robots can’t do: They can’t feel, they can’t see, they can’t
compensate for variations in the materials.”
Knowing what customers want
Employees hone these high-quality knives by
hand, giving them that finishing touch. Sometimes
they resort to unexpected positioning aids in
preparation for laser marking (center).
And the materials, especially, have seen considerable changes.
Special steels and woods, raw materials for hand-made handles, and new requirements for use in the kitchen — Lamson
has had to respond to these. “And learn how to process these
materials to get the best out of them,” says Hayes. Design has
also become a greater part of what customers want in their
kitchen. “Being involved in the market and understanding
what the consumer really needs is important. Continual improvement, continual progress, continual research about materials and processes are key.”
The customers — both professional chefs and amateur cooks — appreciate that. Lamson supplies wholesalers, online shops
and outlets, and is also a major OEM for other sales channels that value products made in the USA. And how do the
customers react to innovations like laser-marked logos on
hand-made knives? “Our customers want that and they love
it,” Hayes says. “Tradition and modern machinery? That’s a
perfect fit,” he adds with a laugh.

16 Express 3/13
Even now, the CO2 laser is
frequently the tool of choice when
processing materials. We have made our
machines with their tried-and-tested beam
source even better. A boost in efficiency and
30 percent less power consumption are,
in our opinion, convincing arguments. For
us, these advances denote true innovation.
TRUMPF offers additional functions
for both beam sources, including
the simultaneous cutting head
positioning device, which significantly
reduces the amount of travel and time
needed for repositioning. Reference cycles
are no longer required, thanks to the new
absolute value measurement system. In
both machine types, the piercing process
has become even more reliable at critical
thicknesses due to multi-stage
piercing with no slag ejection. And
yet, the holes pierced in 15-millimeter sheet
metal are just 2 millimeters wide. That is
essential for cutting narrow curves.
BrightLine fiber is the solidstate laser’s stepping stone into the world
of heavy gauge sheet metal. For the first time
ever, top-class cutting results are possible
even in thick stainless steel. The machine
shifts freely from maximum productivity
and quality in thin sheet to high-quality
cutting in thick sheet with BrightLine
fiber. This is what the word “flexibility”
means to us.

The functional package called smart
nozzle automation guarantees the best
possible cutting results because it monitors

And this is how it’s done:
Greater efficiency
Many people believed that the
options for increasing the energy efficiency of CO2 lasers
had been exhausted. Far from
it! The boost in plug socket efficiency marks a technological
breakthrough for this tested
laser beam source. This is how
it works in practice: This increase in efficiency is based
on a stainless steel resonator
with a high-temperature circuit. To a great extent, this
new cooling concept does
away with energy-consuming compressors, since the
coolant discharges heat directly into ambient air. This
reduces energy consumption
by about 30 per cent.
Greater freedom
New to the TruLaser Series 5000 with its solid-state lasers is
BrightLine fiber. The switchable TruDisk solid-state laser is
the key to an entirely new quality in thick sheet metal processing. In routine operations, it permits quick changes between high productivity at high feed rates in thin sheet and
processing heavy gauges at new quality levels thanks to the
BrightLine fiber function. This lets customers cut smaller
contours quite accurately as well. Additional benefits: When
fusion-cutting stainless steel and aluminum, using the solidstate laser, BrightLine fiber boosts thickness capacity from 20
to 25 millimeters and improves the feed rate for thick mild
steel by up to 16 per cent.

active all around the world. While tendering for this job, the American branch of the
Cologne company came up with a special idea.
It was with a specimen of the final matt stainless steel, mounted on a full-scale model of the
façade, that the company was able to win out
over international competition. The design of
the entire building is just as sophisticated as
the pinnacle. The striking feature is the rotation of the building, with its square floor plan,
by 45 degrees as it climbs to the peak, becoming
smaller in size. As a consequence, the tower’s
façade itself twists as the tower rises. Pohl made
up and delivered the complex stainless steel elements made of a corrosion-resistant chromenickel-molybdenum alloy. These elements are
four meters tall, one meter wide and, taken together, weigh 250 tons.
Extreme precision was called for when fabricating the parts. “One of the major demands,
in spite of the relatively thin material, was to
ensure the flatness and stability of the panels even at high wind loads,” says HeinrichRobert Pohl. The team was able to reliably fulfill this demand using a TruPunch 5000. Additional stiffeners on the rear surface of the panels ensure that they remain absolutely plain and
resistant to buckling, so they cannot become
detached and blow away. “At a height of 400
meters, violent winds can press and tear at the
corners of the building — especially at the panels,” Pohl continues. During Hurricane Sandy,
the elements proved that they could withstand
such forces. With its peak made of glass and
steel, New York City has, since May 2013, once
again had a new landmark.

the electricity which the company uses to run its production machines,
compress air, and control the climate in the factory. A special concrete

A holistic concept
It is no accident that Alois Müller GmbH decided to go for energy-efficient manufacturing. The company itself specializes both in plant and
equipment construction and in energy and building technology. “To an
ever increasing extent, our customers are focusing their attention on
their energy consumption. When doing so, they often prefer to invest
in small or partial projects. They upgrade a heater here or replace a fan
there,” explains Plant Manager Jan-Peter Höhne. “In our case, we had
been thinking about setting up a production facility that is fully oriented
on saving energy.” The enterprise profits from this in two ways. Not only
does this keep costs down. The manufacturing plant also serves as an
exhibit for its own customers. “As equipment builders in southern Germany, we see a unique chance to carry out the development and production of cutting-edge components in the field of heat and electrical supply,” adds Andreas Müller, CEO of Alois Müller GmbH.
Storage in concrete
Like all the machines in the plant, a TruLaser 5030 is also powered by
the photovoltaic unit. The 380 MWh/year are sufficient to heat and cool
the plant and even to provide compressed air, nitrogen for the laser cutting device, and the deionized water needed to refill the heating systems.
Over and above that, heat is stored in the floor. This is where 8,000 meters of thin heat exchanger pipes, filled with water, are arranged in several layers and encased in a 1,000 square meter floor slab. Excess energy
is used to heat the water and thus the concrete floor up to 40 or 50 degrees. If the sun fails to make an appearance, Müller Produktions GmbH
utilizes the energy in storage.

“There is great potential for energy
efficiency in small and medium sized
companies.” Jan-Peter Höhne, Müller Produktions GmbH
Alois Müller stores excess energy
in a special concrete floor slab;
it is warmed up by the water in
the heat exchange pipes.
“We also want our own operations to use 100 per cent of the energy we
produce. We meter our consumption in real time so that we can continuously improve it,” says Höhne. The target: Detailed information should
be available for every component made — both production time and energy use. This makes it possible to plan consumption and synchronize it
with the energy being generated. Gathering this data is a pioneering effort, which is why the company cooperates with the Technical University
of Munich and the Fraunhofer Society in questions of process monitoring. “We want to prove that certain investments are worthwhile and to
launch a multiplier effect. Especially in small and medium-sized companies, there continues to be great potential for enhancing energy efficiency,” says Höhne, thinking about his own customers.
In the future, Müller Produktions GmbH will be making use of additional energy reserves in their Ungerhausen manufacturing facility by
implementing TRUMPF ’s universal cooling interface. It was recently fitted to the laser machine and will transfer to the factory’s climate control system the waste heat generated during the laser cutting operation.
Utilizing waste heat intelligently
The universal cooling interface has already been in operation in the Swiss
town of Densbüren for the past eighteen months. This is where LCD
Laser Cut AG intends to reduce the energy required to heat their buildings as well as to lower power consumption significantly. The company's
targets are to cut back on heating oil by more than 80 per cent, electricity requirements for water cooling and compressed air by 40 per cent,
and thus bring down annual CO2 emissions by 151 tons. This specialist
for rotor and stator packets in electric motors is aiming to achieve this
mainly by utilizing the waste heat generated by the three laser cutting
machines and when compressing air. For this reason, Jörg Heusser, a
consultant at FED Energie GmbH, has made direct connections to a new
central cooling water circuit. The latest machine, a TruLaser 7025, was
connected via the universal cooling interface while two older machines
used custom retrofits. “The connection to the central system is not all
that easy, because the demands are great. The water used to cool the machines must remain constant at 21 degrees Celsius — with a tolerance of
only 0.5 kelvin. But it’s worth the effort, since we are utilizing waste heat
from the laser machines and, in so doing, making the cooling circuit

simpler and more efficient.” Now there are only two pipes per machine —
one for the cooling water feed and one for the return. This is possible
because, thanks to the universal cooling interface, the water is not split
out to the various cooling circuits before it reaches the machine. This
lowers fan noise and reduces dust in the production area. In addition,
the workshops are noticeably cooler in summer.
By using the waste heat that LCD collects from compressing air and
from the three laser cutting machines — now connected to the central
cooling circuit, the company has been able to reduce its heat consumption by some 200 MWh/year. “Once we have connected all our machines
and launch three-shift operations, we won’t need any heating oil at all!
For the interim period, a so-called free cooling unit will provide cooling water for the laser machines, using low-temperature outdoor air instead of a refrigeration system,” explains LCD founder Georg Senn. For
Giuseppe Pasquarella, owner of LCD, it goes without saying that the
company is operating a state-of-the-art energy management system. “We
are a highly innovative enterprise and manufacture high-tech products
for electrical drive engineering. Consequently, an outdated energy concept simply has no place in the picture.”

Anybody can save
With the universal cooling
interface, only two pipes are
required — one for cooling water
feed and one for the return.
All the recently installed units make use of a monitoring system. This
means that operations can be continuously reviewed and optimized.
Since LCD implemented its energy management master plan eighteen
months ago, savings have been appreciable. “So far, we have connected
three of the six machines to the system and thus achieved about fifty
per cent of the envisaged total savings. This goes to show that savings
are realistic and really can be achieved,” is how Jörg Heusser sums it up.
He feels it is always important to consider local conditions when selecting energy saving concepts. “There is no such thing as a one-size-fits-all
concept. Instead, there are many different building blocks. When these
are assembled sensibly, however, the saving potentials present in virtually every company can be utilized.”

Metalworker
Goldsmith Viola Hermann embeds rainbow colors in precious metals.
Anyone walking into Viola Hermann’s jewelry
studio is sure to be fascinated by the blazing
array of colors. Viola Hermann is a passionate goldsmith. Her trademark: She combines
acrylic in every color of the rainbow with silver and gold alloys to create unusual pieces
of jewelry. In addition to creativity and a pronounced feel for aesthetics and style, this Stuttgart woman is distinguished by one thing above
all: a thorough apprenticeship in the artisan’s
trades, similar to a metalworker’s training.
A solid foundation
Angelika Grossmann, Viola Hermann
Even as a schoolgirl, Viola Hermann helped
out in her uncle’s goldsmith shop. This was why
it was quite clear to her when she left school
that this was the profession she wanted to
learn. “The idea of making this static material
bend to fit my visions appealed to me. And it
is only with a sound knowledge of the materials that you learn how to handle them properly,” recounts the 43-year-old. After an apprenticeship lasting three and a half years
and a further five years as a journeyman,
the jewelry designer passed her final examinations as a master goldsmith. During this period, she learned everything
she needed to make jewelry: embossing,
mounting, turning, polishing, enameling, galvanizing, soldering, welding and
setting stones. And she works with the
most varied of materials. She was quick to
determine that classical and conventional
work did not suit her and this is why she specialized in colorful jewelry creations that are
in great international demand.
The artisan’s touch
In her studio, which is located in downtown
Stuttgart, Viola Hermann and her partner perform almost every step in the work themselves.
Many of her utensils are the same as you would
find in any metalworking shop — it’s just that
hers are much smaller. There is a miniature
smelting furnace for all kinds of cast metals,
pieces of metal, and used jewelry that customers have asked her to rework. A lathe, a polishing unit, and a precision-grinding machine are
also on hand. “I do farm out some jobs — laser
engraving or some cast parts, for instance —
but I do most of the work myself,” the goldsmith explains. The same applies to individual
tools such as embossing dies. Countless drawers hold Viola Hermann’s models and the casting molds she has manufactured to her own
design. She creates rings, pendants, earrings —
even chain links — entirely by hand. To make
jewelry, knowing about mathematics, chemistry and physics is just as essential as a fine
touch and muscle power. “Processing metals demands plenty of strength. At the same
time, I have to be very careful and know how
far I can go with a certain material before it
breaks or cracks while being shaped,” explains
Hermann. But this is simply the exciting challenge that her work poses.
Tell us,
Ms. Hermann…
… what do you see as your
greatest strength? And your
greatest weakness?
I am honest, genuine, creative, but
frequently indecisive, inconsistent and
stressed, as well.
… how would you characterize
yourself in a few words?
I am obstinate, headstrong, and have
learned to be independent and to
stand on my own two feet. I hold a
healthy curiosity about everything
new and old. I love learning things and
hope that this will never change —
and that I will always appreciate the
little things in life.
… where do you get your energy?
Light, the air, the sun, yoga, music.
… what would you take with you
to the proverbial desert island?
Tools, music, fire and water.
An interesting connection
Our goldsmith has developed a process
for her jewelry to connect metals and
acrylic by form-fit and friction, so that
both elements retain their independence. The combination of cool silver with rainbow-colored acrylic
that she collects from all over the
world creates a most spectacular
effect. “I work in layers. I start off
by making a silver mount. I can add
embossing or engravings to it — or
particles of gold leaf. On top of all that,
I place a polished acrylic ring in the desired color,” explains Viola Hermann. The
wealth of variations in material, color and design is gigantic. “It’s always something quite
special to work with the customer to create an
individual piece of jewelry. When actually making it I am merely the tool lending shape to
the idea.” www.viola-hermann-schmuck.com
