Dear readers,
The Galaxie ® train is rolling – this is the unanimous opinion
among experts in universities and industry. And many of them
go a step further: it’s high time for machine builders to hop on
board if they don’t want to be left standing by the way at thestation of high technology. Three years on from the spectacular premiere at the Hannover Messe 2015, the Galaxie ® Drive
System is meanwhile regarded as a basic technology whichenables two key sectors of the German economy – engineeringand automobiles – to make the next developmental advance interms of precision, energy consumption and material use. Our
motto for this year’s Hannover Messe sums it all up very neatly:“Make the impossible possible. Galaxie® – superior on principle”.
To return to my original analogy, the train is rapidly picking up
speed. Based on our experience during the recently completed market maturity phase, we have now laid the foundation for
the establishment of a modular Galaxie ® portfolio, which will
pave the way for new applications with special performanceor installation requirements with different designs and variants.
Among other things, the exhibits at our stand F10 in Hall 15
will focus on the use and benefits of Galaxie ® in machine tools,

cutting heads and robot welding guns. Moreover, for the firsttime, WITTENSTEIN will show how operating data can be transmitted to an IoT cloud using a Galaxie® Drive System equippedwith sensors.
As co-founder and former Managing Director of WITTENSTEIN
subsidiary attocube systems AG, I am obviously particularly
pleased to have two exciting news items to report from Munich.
First, the company will move into the new NanoFactory mid-way
through the year and second, on pages 22 and 23 of this issue
we celebrate exactly twelve months since the market launch ofa breakthrough industrial application for the IDS3010 Industrial
Displacement Sensor – as the “technological core” of an interferometric calibration system from Etalon AG.

Galaxie ®:New designs
for new applications

From the outset, the Galaxie® Drive
System has set a new benchmark withperformance features that were previously
unattainable. The technological superiorityof the Galaxie® principle has been provenin numerous applications over the last few
years. Not surprisingly, customers regularly
approach us with ideas for new uses.
WITTENSTEIN has now responded tothis need with a modular system concept
and new designs that open up yet moreinnovative applications for Galaxie®.

Our experience during the last three years – with several hundred
gearboxes and drive systems meanwhile in operation – confirms thatthe performance data in the original Galaxie® specification has not
only been achieved but exceeded by a large margin. “On top of that,countless applications have shown that with its low wear, this Drive
System also sets benchmarks when it comes to reliability,” says Nadine Hehn, a sales engineer in WITTENSTEIN’s Startup Galaxie team.
Versatility embedded in the “Galaxie® DNA”
Furthermore, during the run-up to full-scale production since themarket launch in 2015, the foundation was laid for the establishment of a modular Galaxie® portfolio, which with five different sizes
and four variants will pave the way for new applications with special
performance or installation requirements. The Galaxie® D (D = drive)
Drive System is a mechatronic unit comprised of a specially developed, high performance synchronous motor and a Galaxie® gearbox.

4 moveIt was the desire expressed by some customers to just use the hollow-shaft gearbox and integrate it into their own motor unit or servo
motor which led to the Galaxie® G (G = gear) as a mounted version
for servo motors. It also became apparent that there would be goodjustification for a right-angle version of the gearbox – and the Galaxie® GH (GH = gear hypoid) was born. “Flexibility and versatility,and hence openness to new requirements, have been a part of the
Galaxie® DNA from the start,” adds Bastian Minke, he too a Startup
Galaxie sales engineer.
New Galaxie® variants at the Hannover Messe 2018
The new Galaxie® D Drive System in size 085, which will be unveiledat the Hannover Messe 2018, is further evidence of this application
oriented modularity. It is designed for use in axes with very high compactness and precision requirements or for applications where hightorsional rigidity and freedom from backlash are called for in addition

to torque. “Compared to a strain wave gearbox with the same torque,this Galaxie® Drive System delivers more than double the maximum
output speed and almost three times better torsional rigidity,” Nadine
Hehn explains. On the one hand, the size 085 Galaxie® D enables
new applications for the machine tool industry in this way while on
the other, it creates opportunities in new fields such as automotive
machinery, handling systems or material removal robots.
The Galaxie® DF Drive System is another new variant in the productfamily. The “F” stands for “flat” – and an up to 30 percent reduction in length compared to the Galaxie® D. Bastian Minke reveals
how this was achieved: “This space saving is possible because themotor is positioned radially around the gearbox rather than axiallybehind it.” “Superior on principle means users will not have to forego the familiar performance features of the “big brother” – like thehigh torque density, zero backlash kinematics and low wear behavior – with either of the 110 and 135 sizes which are initially available. Milling machines are among the applications to profit from theProduction and organization tailored to
fast delivery
The modular portfolio and multiple designs allow Galaxie® to expand
the mechatronic solution space in numerous use scenarios. Moreand more machine manufacturers are recognizing how the Galaxie® portfolio enhances the performance of high-tech machines, creates perspectives for new machine generations – and gives users
a technology lead. “That’s why we didn’t simply build up a modern
production base with high performance precision machines; we also
designed the processes within the startup organization so that shortlines of communication and tolerable delivery times are guaranteed,”says Volker Sprenger, Startup Manager Galaxie.
Superior on principle
Instant added value without long waiting times – Galaxie ® proves that
this does not mean squaring the circle. This is all the more importantin that Galaxie® causes many high performance machines to be completely “reinvented”, putting their manufacturers even further into thelead. All of this is possible because Galaxie® has meanwhile gained
general acceptance among scientists as an independent generation
which is superior on principle.

The manufacture of composites for the aerospaceindustry presents some very daunting challenges
involving complex, automated production steps
where absolute precision and repeatability are vital.
Electroimpact, a world leader in aerospace toolingand automation headquartered in a suburb of Seattle(USA), trusts in WITTENSTEIN SE’s torsionally stiffand completely backlash-free Galaxie® gearbox forexactly this reason.

With its unique combination of intense precision abilities in a compact space, Galaxie® delivers next-generation performance for engineering efforts by Electroimpact – with aircraft manufacturer Boeing
just one of those to reap the benefits.
New machine generation for the wing panels of the
Boeing 777X
Four Automated Fiber Placement (AFP) machines designed by Electroimpact representing the latest state of the art are used for thedevelopment and serial production of the future Boeing 777X wing
panels and wing spars at the Boeing facility only a few miles away.
Only one step is required – as opposed to three in the past – tomake the forward and rear wing spars, which are up to 33.5 meters
long. A robot head weighing about 0.5 tons is integrated in a mobile
gantry structure 6 meters wide for this purpose. It applies several

hundred layers of epoxy resin-impregnated carbon fiber strips andsheets to the basic structures with absolute precision. After applying
one sheet, the robot head does a 180° turn, positions itself anew andapplies the next sheet in the opposite direction. The AFP machinefor the wing spars is additionally capable of swiveling the robot headthrough ±90° with the necessary dynamics, so that the U-shapedspar structures can be made in a single operation.
Galaxie®: Enabler for the new
AFP composite manufacturing technology
The special kinematic precision and repeatability of the mobile gantry structure and the robot head which can be swiveled through any
angle are the key to the high productivity now achieved in the aircraft part production process. The WITTENSTEIN-built Galaxie®
was welcomed by Electroimpact’s engineers as a gearbox solution
which, owing to its special design with separate thrusted tooth kinematics, meets the high technical demands of the AFP machines inevery respect. Galaxie®’s crucial benefits are its high torsional rigidity
and complete freedom from backlash, enabling ultra-precise positioning at each direction reversal of the gantry and robot head during
the application processes. Zero backlash can be realized throughout
the drive system’s entire lifetime through selective inner tensioning
and the build-up of a hydrodynamic lubrication film during surface
contact. On top of this, the compact design permits more flexible
motion control for use in the swivel axes. For the first time, Galaxie ®
allows highly complex composite aircraft parts to be manufactured
efficiently in one piece with the required precision – successfully underlining its claim to be the “Next Technology Drive” for high performance engineering efforts by Electroimpact.

Galaxie ® Superior on principle“The new gearbox generation” – this is how it was referred to in umpteen
publications back in 2015, when the Galaxie® Drive System waslaunched at the Hannover Messe and honored with the Hermes Award.
What we at WITTENSTEIN knew all along is now also a recognizedfact in the scientific community: the first academic textbook testifying
to Galaxie® as a new and independent gearbox generation is due toappear at the end of the year.

The textbook Machine tools and manufacturing systems 3: Mechatronic systems,
controls and automation will be edited by Professors Christian Brecher and Manfred
Weck of the Department of Machine Tools at RWTH Aachen University. The left diagramof the Galaxie® operating principle is taken from the textbook’s ninth edition, which will
be published at the end of the year.

It’s an undisputed truth: Galaxie® is superior on principle. Several
decisive features – dynamic teeth instead of rigid gear wheels, hydrodynamic tooth contact over the full surface and a new type ofbearing with a segmented outer race ring – mean that Galaxie® isclearly superior to other, established principles in all key technicaldisciplines when measured against the market standard. Galaxie®
provides exceptional freedom from backlash, synchronous running,
stiffness and torque density – all at once and with no structural ordesign compromises. This is no exaggeration – it’s a scientifically
proven fact which has been confirmed in numerous real applications.
Logarithmic spiral as the basis
for scientiﬁc reasoning
The “International Conference on Gears”, hosted by the Instituteof Machine Elements / Gear Research Centre (FZG) at TU Munichin September 2017, is the world’s most important academic conference for gear and transmission development, with more than

8 move700 participants. Also on the agenda were two presentations, reviewed and approved by professors, on the Galaxie® system – which
demonstrated the Galaxie®’s status as s a new gearbox generationby scientific abstraction.
“The underlying scientific reasoning was that Galaxie® introduced themathematical function known as the logarithmic spiral as a fundamentally new principle in gear unit design,” explains Thomas Bayer,
inventor of Galaxie® and today Manager Innovation Lab at WITTENSTEIN. “The toothing takes the form of an input polygon, aroundwhich the individual teeth are grouped, leading to full-surface contact
and mathematically precise synchronous running.” In the meantime,
both the theoretical functionality of Galaxie® and its technical performance features and benefits have become generally accepted in thescientific community. This is reflected, for example, by the inclusionof the new gearbox generation in standard reference works for research and teaching – like the ninth edition of “Werkzeugmaschinen

und Automatisierung” (Machine tools and manufacturingsystems 3: Mechatronic systems, controls and automation),edited by Professors Christian Brecher and Manfred Weck of
the Department of Machine Tools at RWTH Aachen University. A separate chapter dedicated to the Galaxie® gearbox
will describe the design, operating principle and key benefitsof this new generation.
Technological superiority confirmed by the“Galaxie® community”
Yet a “Galaxie® community” of enthusiasts, who have praised
the new gearbox generation as a “milestone in engineering”
in various publications and presentations, emerged among
businesses and industry associations even before scientificproof was established. The German Research Association
for Power Transmission (FVA), whose basic research as wellas insights gained from research projects – for instance on
highly dynamic plain bearings – were adapted to the Galaxie® kinematics and leveraged for the development of the
gearbox, is one such admirer. In its book “50 Jahre FVA:
sharing, drives, innovation” (50 years of the FVA: Sharing,
drives, innovation), the FVA mentions the WITTENSTEIN Galaxie® in the same breath as a long list of outstanding inventions of the modern era, on a par with the pioneering featsof Leonardo da Vinci, August Otto, Friedrich Fischer and
Rudolf Diesel. The German Engineering Federation (VDMA),
too, is a member of the “Galaxie® community” because leading companies in the industry – among them Profiroll Technologies, DMT Drehmaschinen, Broetje Automation, MAKA
Systems and NIMAK – trust in this innovative transmission
and drive technology and have confirmed the new gearbox
generation’s technological superiority in practice. It is therefore not surprising that experts are meanwhile predicting that
the Galaxie® technology is on the verge of exponential market penetration – especially since WITTENSTEIN has established a modular product portfolio which will pave the way
for new applications with special performance or installation
requirements with different designs and variants.
Times are changing and Galaxie® will continue to make theimpossible possible in the future – as a new generation, as a
gearbox and as a drive system.

Galaxie® – the ideal solution for robotic drives
Professor Karsten Stahl is Head of the Institute ofMachine Elements and the Gear Research Centre(FZG) at TU Munich.

move: When did you first hear about Galaxie®? What thoughts andideas occurred to you spontaneously?
Professor Stahl: I first set eyes on the Galaxie® gearbox in Igersheimat the end of 2013. I was struck by the notion that a gearbox withsuch a totally different physical principle compared to establishedgear trains could have so many advantages.
move: What, in your opinion, is the single most important differentiator of the new Galaxie® generation?
Professor Stahl: I would say that the high stiffness is the outstanding
feature. In contrast to gear drives, where the tangential force mustbe transmitted by a small number of Hertzian contacts, the Galaxie®
gearbox has a large number of full-surface sliding contacts. Significantly higher rigidity can be achieved in this way due to the natureof the system.
move: Exceptional freedom from backlash, synchronous running andstiffness all at once – what new solution concepts and applications
does Galaxie® enable in the machine tool industry and beyond?
Professor Stahl: The Galaxie® gearbox seems to me to be the ideal
solution for robot drives, especially when very high stiffness is called
for. I’m assuming that robots will play an increasingly key role in themachine tool sector, whether autonomous or collaborative. Robots
with relatively low resilience can certainly score here in combination
with ultra-stiff drives.
move: Galaxie® introduced the logarithmic spiral as a brand newprinciple in gear unit design. How will this be implemented didactically and methodologically in academic teaching?
Professor Stahl: The logarithmic spiral has not actually featured yetin lectures at the Institute of Machine Elements. It looks like a rethink
will be necessary here, and our curriculum will need to cover the
special characteristics and benefits not only of the involute but alsoof the logarithmic spiral.
move: Evolutionary or revolutionary – which category, in your view,is a more apt description of this invention as a technological innovation?
Professor Stahl: I would definitely class the Galaxie® gearbox asa revolutionary innovation. After all, it was developed making conscious use of creativity methods, the aim being to depart from traditional ways of thinking and explicitly seek alternative physical principles. I’m convinced that it would have been impossible otherwise
to come up with a gearbox that is based on totally different principles from conventional gear drives, yet has characteristics which areclearly superior to those of a normal gear.

Muy bien
premo servo actuatorwins over Spanish supplier Zayer

The compact design of the cutting heads and theability to rotate them up to 30° during the machining
process are key features of Zayer’s ARION bridge typemilling machines.
The machine-tool manufacturing company, at homein Vitoria (northern Spain), opted for WITTENSTEIN
alpha’s space saving and power dense premo servo
actuators. Its verdict: “muy bien”.

ARION supplements the larger and well-established TEBAS andNEOS bridge type milling machines as a separate series with a lower
loading and milling capacity that is ideal for machining small parts.
It was redesigned with a comparatively compact and space saving
layout for this reason – and these same requirements also had tobe met by the ARION’s brand new cutting heads. The answer: theservo drives are integrated directly in the cutting heads. Size, power

10 movedensity, modularity – it didn’t take long for WITTENSTEIN alpha’s
premo servo actuators to be revealed as the optimum solution. All
the more so because these motor-gearbox units allow the cutting
heads to be continuously rotated through 30° while machining complex geometries – unprecedented among bridge type milling machines in the ARION’s performance class.
Sound advice and a modular system for the perfect design
The ingenious modular system based on novel, space saving designprinciples and the efficient support from the engineers at WITTENSTEIN S.L.U., WITTENSTEIN’s Spanish subsidiary, meant the perfect premo servo actuator configuration was achieved for the ARION’s cutting heads. The ARION user’s intended machining process
plays an important role here: either the servo actuator “simply” hasto execute a pure positioning motion or it must also slave the milling
axis continuously. “In the former case, one premo servo actuatoris installed per axis; it first of all positions the head precisely andthen starts machining the workpiece,” explains Luis Calleja, Manager

WITTENSTEIN Spain
WITTENSTEIN S.L.U was established in Barcelona in November
2011. WITTENSTEIN’s Spanish subsidiary and its Managing Director, Thorsten Weiß, are proud of the steady growth in sales – not tomention the payroll. Xabier Rodriguez, a 35 year-old engineer, is oneof eight staff to work there at present. He serves northern Spain fromthe Sales Office in San Sebastian. That makes him a close neighborof milling machine manufacturer Zayer, whose headquarters are only
sixty miles or so away in Vitoria.
“Zayer is one of our key accounts and one of Spain’s most innovativeengineering companies,” Xabier Rodriguez enthuses. “We’ve built up

premo servo actuator:
scalable for perfect performancea trusting and constructive partnership over the years, and each new
project generally kicks off with us getting together to discuss the machine’s design. As soon as the drive technology becomes a central
issue during the development phase, Zayer gets in touch with us.” In
the meantime, WITTENSTEIN products are first choice for the Spanish supplier – in all axes, from the gearboxes through the servo actuators to the racks and couplings. The new ARION series of machines
is the newest manifestation of this successful partnership.

Dynamics, speed, positioning accuracy, output geometry, encoder design and degree of connectivity – theingenious premo system allows motors and gearboxes to be configured modularly to obtain customized servo
actuators with graduated performance characteristics tailored to the particular application.
“premo base line” – the basic class – provides optimum performance for all positioning tasks.
“premo advanced line” – the dynamic class – guarantees high precision for special positioning tasks where
higher dynamics and forces are called for. “premo high line” – the extra class as used in the Zayer ARION –convinces with high torques and torsional rigidity, leading to the very highest levels of productivity, precisionand versatility.

One premo servo actuator per axis
positions the head precisely and thenstarts machining the workpiece.

The resulting functionality is crucial if the ARION is destined for highly mechanized applications like mold and die making – and equivalent to that offered by the
NEOS, Zayer’s larger model.

Development at Zayer. “If the axis needs to be slaved, it is equippedwith two premo actuators which are electrically preloaded with one
another.” The resulting functionality is crucial if the ARION is destinedfor highly mechanized applications like mold and die making – andequivalent to that offered by the TEBAS and NEOS, Zayer’s larger

Successful market launch
When ARION bridge type milling machines featuring premo servo
actuators in the cutting heads were exhibited at a Spanish engineering show, the feedback was highly encouraging. “Eight of these machines were subsequently sold very quickly, and five more have since
been put into operation by customers in the aeronautics and die
manufacturing industries,” says Luis Calleja, who is delighted withthe successful market launch.
User experiences to date have been more than satisfactory – so that
Zayer, too, has no hesitation in giving the premo actuators an altogether positive verdict: “muy bien”.

Cutting-edge technology from
northern Spain

Based in Vitoria (Spain), Zayer employs around 150
people and is one of the world’s leading manufacturersof high-tech bed type, moving column, gantry andbridge type milling machines.
Approximately 80% of Zayer’s total milling and machining solutions are exported: they are used, among
other things, to machine nose wheels, turbines andfuselage sections in the aeronautic industry, to manufacture platforms, hubs and rotors for wind energy, tomake cross rails, bogies and structures for railways, tomachine large components in the energy industry or
in foundries and to build turbines for the hydroelectric

Applications

V-DriveBasichaprotec GmbH was pursuing several goals when it launched thedevelopment of a new series of rotary converters for electronics
production: the ability to adapt the conversion rate dynamically, theshortest possible cycle times and more accurate positioning. Those
goals were achieved with the help of high performance V-Drive Basicworm gearboxes from WITTENSTEIN alpha.

The dynamics
of worms

Rotary converters round off the haprotec portfolio of lifters and transfer systems, with which workpiece carriers or masks are supplied to
the various placement, manufacturing and testing processes in electronics production. “In a combined rotation and conversion step, theproduct being conveyed – for example, a solder frame – is first of all
separated ahead of the converter module, then pulled in by the drive
unit in the rotary station, positioned, turned through 90° with a safe,
vibration-free rotary motion and finally discharged again. Rotary converters that work on two levels – one for feeding and one for return– are particularly efficient here,” explains Christian Happ, proprietor
and CEO / General Manager of haprotec.
Special requirements for a new, dynamic rotary unit
The development specifications for a new rotary converter for workpiece carriers with a maximum overall weight of 15 kilos were absolutely clear: to further optimize the actual rotary motion – and hence
the performance of the module as a whole. “We identified two possible ways to boost efficiency: to add dynamics to the rotary motion
according to the workpiece and to increase the rapid speeds when
the rotary unit is reset,” recalls Holger Engelhart of haprotec’s Electrical Design department. “We were hoping to achieve significantly
shorter cycle times here – and correspondingly higher throughput.”

12 move

The significantly better
positioning accuracy andrepeatability are largely
due to the V-Drive Basic’s
special tooth geometry.

The new drive solution had to fit into the enclosure such that theworkpiece carriers could be returned on the bottom level – without
altering the overall height and regardless of any third party systeminstalled upstream. The close cooperation between his company as
the manufacturer of the machine, Siemens as the motor and controller supplier and WITTENSTEIN alpha as the specialist for transmission technology resulted in a drive unit that meets all of the above
requirements – and in some cases even exceeds them.
V-Drive Basic: Dynamics and positioning accuracy
in a power dense package
Siemens chose a SIMOTICS S servo motor with a SINAMICS V90
converter for this task: this combination enables dynamic and accurate positioning of the new rotary converter as well as precise motion
control. WITTENSTEIN alpha’s V-Drive Basic worm gearbox provides
all of these performance features for the rotary converter in the shaft
version. The redesigned involute toothing of the worm is key here.
The positioning accuracy of less than 15 arcmin which is specified
for the V-Drive Basic and required by the application is permanently achieved by the dynamic rotary converter. “What is particularlyinteresting here – and of course positive too – is that even different
rotational speeds have no noticeable impact on the precision of therotary motion,” says Holger Engelhart. Finally, thanks to the geometric design and manufacturing execution of the gearing, the V-Drive
Basic additionally impresses with high torque reserves, so that thefull power potential of the servo motor is unlocked for the rotary converter. In spite of all the dynamics the worm gearbox is acousticallyvery discreet, with a maximum of 65 dB (A) at full load and no morethan 50 dB (A) at medium speeds.
Success all along the line
Christian Happ sums up: “The bottom line is that the new, dynamic
rotary converter has acquired a high quality drive system combining altogether adequate positioning accuracy with excellent value formoney”. “That’s why we also decided to use the drive package withthe single-stage V-Drive Basic and a ratio of 40 for series production.”

Anyone who has ever attempted to screw a mobile

have no trouble imagining the kind of requirementsthat are specified for the automatic screwdriving
systems used during the micro assembly ofelectronic items.

Screwdriving madesimpleSTÖGER AUTOMATION, the screwdriving and fastening systems
specialist, has come up with a groundbreaking screwdriving unit featuring highly dynamic small servo motors from the cyber ® dynamic
line family and high-resolution servo amplifiers belonging to the simco® drive series which sets benchmarks in terms of cycle times, automatic feeding of the fasteners and screwdriving quality. The spacesaving external dimensions and low mass of these industrial grade
small servo motors on the one hand and the smart servo amplifiers, with their high switching frequency and exceptionally high current resolution, on the other were the crucial features identified by
STÖGER AUTOMATION in this servo drive solution.
Quick and easy handling of delicate screws“To insert a screw two millimeters long, with a thread just one millimeter in diameter and a head two millimeters across, in under a second
and then process it efficiently without using sensors to measure thetorque – that was a really daunting challenge,” recollects Artur Kornelsen, a developer at STÖGER AUTOMATION. It was made evenmore difficult by the high process speed. “Cycle times of less thana second were stipulated, which meant the screws had to be fed as
intelligently as possible,” says Lorenz Stöger, the company’s founder. “Feeding hoses were rejected due to the tiny screw size while
pick & place would have been too slow – we therefore opted for ascrewdriving system with two spindles, where one drive is responsible for the screwing process while the other makes the next screw
available in parallel.” However, speed was only one aspect because
the screws are delicate and have to be inserted very carefully; what’smore, the speed has to be reduced for tightening to ensure a secureconnection. Finally, the two-spindle screwdriving system needed
to be simple to adapt to different screwing scenarios with different
screw sizes and types, thread lengths, torques and speeds.

cyber motor, we were able to develop a solution for supplying, inserting and tightening miniature screws with unprecedented efficiency,
unlike anything ever seen before in the procurement markets of electronics manufacturers or other, similar users,” explains Artur Kornelsen.
Out of the four small servo motors from the cyber ® dynamic line
family which are used in the screwdriving system, two are designedwith an integral ball screw drive. As a highly precise solution for theZ axis, they position and guide the screw on the workpiece. The other two motors execute the rotary screwing movement. “The motors
are distinguished by an excellent ratio of high torques to low motor
weight,” adds Carolin Ank, Product Manager at WITTENSTEIN cybermotor. “Owing to the high dynamic factor, they’re just as suitable for
rapid acceleration as they are for short movements with frequentchanges of speed.”
Each motor is operated by a servo amplifier belonging to the simco®
drive series, providing high-resolution current control in measuring

Kornelsen comments. “The entire development step for a miniaturized torque sensor was eliminated as a result.” Complete screwing

which are the norm in micro assembly processes, very precisely with

More dynamics in the drive means more output fromthe machine – for Schmale Maschinenbau GmbH, it
was a logical decision to equip their high performanceSPEEDMAX S wire bending machines with servo motors
in the cyber® power motors series. These extra-powerful
motors were adapted by WITTENSTEIN cyber motor tothe customer’s individual requirements, for example themass inertia was reduced to a minimum, thus providing
the starting point for the machine’s high acceleration andextremely short cycle times.

cyber® power motors are extremely powerful servo
motors that combine an excellent power-to-weightratio with optimal efficiency.

The development of the motors, which feature a holding brake, multiturn absolute encoder, temperature sensor and angled receptacles and are precisely attuned to the novel machine concept, wasa joint project by Schmale and WITTENSTEIN cyber motor. “Without
those motors, this version of the SPEEDMAX machine with this performance data would never have been feasible,” observes Andreas
Goseberg of Service & Sales at Schmale Maschinenbau GmbH.
The name of the new wire bending machines says it all: a SPEEDMAX S, for example, can produce as many as 200 parts with up to
20 bends each per minute. “Since there are more cycles, customers
using a SPEEDMAX can now achieve a much higher output per time
unit and manufacture their wire bending parts at a substantially lower
cost,” Andreas Goseberg asserts. This increased efficiency is theoutcome of an unusual underlying concept for the SPEEDMAX – inwhich WITTENSTEIN servo drives play a leading role.

WITTENSTEIN servo technology: At the forefront of the“wire bending revolution”
According to Schmale, the SPEEDMAX philosophy is currently revolutionizing wire bending technology. “The production speed of conventional CNC machine concepts with finger benders or wire bending slides has already been stretched to the limit,” Andreas Goseberg
adds. “We’ve managed to unite the benefits of both concepts in theSPEEDMAX but without the drawbacks.” The integration of high performance servo actuators which meet the requirements for the newmachine series was a basic precondition. “Schmale opted for the

arranged in a ring around the rotary table, which get their respective jobs done – bending, embossing, notching, flattening, joining,
punching, swaging – in less than 0.2 seconds. “All in all, roughly 90
servo motors are installed in the machine and synchronized with one
another by means of virtual curves. They can perform precisely coordinated motion sequences in the region of a few hundredths of

a second in this way,” explains Philipp Maurer, a sales engineer at
WITTENSTEIN cyber motor. Thanks to their very low mass inertia, themotors themselves only need a small amount of torque for self-acceleration, enabling correspondingly high acceleration in the workstations of the SPEEDMAX as well as in the rotary table. Andreas Goseberg sums up the situation: “More torque is therefore available forthe process and the machine’s cycle times are extremely short. Morethan three finished parts leave the machine every second as a result.”
Servo technology for the entire SPEEDMAX series
The SPEEDMAX S for wire thicknesses from one to four millimetersis the smallest model in this bending machine series from Schmale.
The SPEEDMAX M and the SPEEDMAX L are designed for thicker
wires. They, too, harness the power of cyber ® power motors in orderto realize highly dynamic, precise and efficient production of wirebending parts.

Thanks to WITTENSTEIN cyber motor’s servo technology, each bending station gets
its particular job done in less than 0.2 seconds.

The Schmale Maschinenbau SPEEDMAX is designed as a rotary table machine with up to 20 workstations.

WITTENSTEIN Sweden

New
world record
for milling
16.4 liters of solidmaterial per minuteLife in the little village of Virserum in Sweden’s historic Småland province is generally
very tranquil. Yet quite the opposite was true last October, when leading aerospaceindustry representatives got together at an in-house exhibition hosted by machine
tool maker Modig Machine Tools AB. It wasn’t the product portfolio that was thefocus of attention, though – it was a new world record in which a whole series of
WITTENSTEIN products played a crucial role.

Established in 1947, Modig Machine Tool AB specializes in highspeed machining centers and is a global leader when it comes to aircraft production equipment. Top manufacturers like Airbus, Boeing,
Bombardier or Cessna are all part of Modig’s customer base. They
particularly have confidence in the machine builder’s customized solutions and in the continuous development and improvement of the

20 movemachining technologies, for example the reduced production times.
Johan Sjoelin, Managing Director of WITTENSTEIN Sweden / Denmark, and his team have for many years supported Modig’s efforts
to fulfill these high expectations. “The partnership between Modig
and WITTENSTEIN has grown steadily stronger over the last few years. We started off with small projects to do with product and motorEvery RigiMill milling machine includes the following

sizing and selection, each one adding to the customer’s overall impression of our know-how and experience. The fact that almost 70
components of ours can be found in the new RigiMill is the outcomeof this mutual, trustful cooperation.”
RigiMill – roughing and ﬁnishing in aluminum or titanium
Thanks to the RigiMill milling machine from Modig Machine Tool, it
is now possible for the first time ever to operate one machine forhigh speed roughing and optimal finishing. Customers can choose
between two preconfigured gantries, which were specially developed for demanding metals such as titanium or aluminum. “It wasvery important that the RigiMill be designed with much higher dynamics. The master-slave function of our cymex® 5 sizing software
was exactly what Modig was looking for because it lets you map twoelectrically preloaded drives. By tensioning each other, the masterand slave eliminate backlash from the drive train and increase themachine’s stiffness”, explains Johan Ralmark, a sales engineer at
WITTENSTEIN Sweden / Denmark. But is that really enough to set a
new world record?

16.4 liters of solid material per minute –with WITTENSTEIN’s help
October 4, 2017: The distinguished visitors to the Modig in-house
exhibition have all gathered around the RigiMill to watch. Their smartphones are ready and waiting. The machine starts up. The motor
accelerates to 18,000 rpm. The 295 horsepower are unleashed. The
countdown begins: 60 seconds! They’re probably the longest 60 seconds the Modig crew have ever spent.
A quick check suffices to confirm that a new world record has been
set for milling – 1001 cubic inches or 16.4 liters of solid material per
minute! Johan Sjoelin is among the well-wishers: “Congratulations to
the entire team at Modig Machine Tool! We’re every bit as proud as
you are that our components have contributed to the new world record in this way. And we’re looking forward to helping Modig defend
the title in the future.”

Applications

Since the successful launch at the Hannover Messe 2017, the
IDS3010 Industrial Displacement Sensor from attocube systems has
opened up a whole series of interesting applications – for example in
the LineCal® interferometric calibration system from Etalon AG.
This Braunschweig company’s calibration system is used forvolumetric compensation of systematic geometrical deviations in
medium to very large machines with between three and six axes.

Laser interferometry:
Ultimate precision in machine calibration

The IDS3010 determines the effect of the combined axis
deviation by measuring directly at the tool center point(from left to right: Daniel Raschke, Etalon, and Dr. Danilo
Schmidt, attocube).

“It measures positioning deviations, straightness, pitch, yaw and rollin all three axes as well as the perpendicularity of these axes relative
to each other,” explains Daniel Raschke, who is responsible for sales
and product management at Etalon. “Since the recurring setup andalignment of the calibration is not necessary for the LineCal® system,
it outperforms conventional single and multiple-beam interferometers, so that a complete, unattended measurement routine can be
carried out in just sixty minutes. This significantly reduces the timeand costs for calibration.”
All 21 deviation parameters in under an hour
To enable all 21 systematic deviation parameters to be measured,
Etalon has developed a measuring frame which can be specifically
adapted to almost any machine needing to be calibrated. The eyesafe sensor heads of the IDS3010 are arranged on this frame for
capturing specific measurement lines that are needed to create ahighly precise geometric image of the machine. “The machine follows the pre-installed measurement lines automatically and sequentially. The patent-pending LineCal® method enables any deviations

22 movebetween the target distances of the machine and the actual distances in space to be recorded with sub-micron accuracy via the interferometer channels,” Daniel Raschke adds. “Our Trac-CAL software
calculates the deviations for all machine axes and outputs control orcustomer-specific compensation data.”
The future: Calibration in space with lightThanks to LineCal® – and the IDS3010 – Etalon has opened up novel
future avenues for calibrating small to medium-sized machines. The
machine-specific measurement frame, together with the IDS3010
fiber-based interferometer, creates defined conditions for volumetric compensation of all deviation parameters, reduces the time andeffort for setting up measurements to a minimum and makes themeasuring system mobile.
This makes it an attractive option for the most diverse use scenarios – from repeated calibration of a particular machine to calibrating
identical machines in the same series, for instance as an automated
final acceptance measurement on the manufacturer’s premises prior
to shipping.

Etalon AG
Specialists forinterferometriccalibration technology
Etalon AG was founded in 2004 as a spin-off
company of the Department of Coordinate
Metrology at the German National Metrology
Institute (PTB) in Braunschweig. “Since then,we’ve increasingly specialized in interferometric calibration technology,” recalls
Dr. Heinrich Schwenke, CEO of Etalon AG.
“Today, we’re a provider of applications for
CMMs and machine tools as well as scientificapplications, with a set of system solutions
for precise and comprehensive geometricanalysis, monitoring and accuracy improvement. Ultimate precision – as a preconditionof controlled, deterministic and reproducible
manufacturing processes – is our main goal.”
Etalon is a key technology partner for manydifferent customers and industries – in themechanical engineering, industrial instrumentation, automotive, aerospace technology and research sectors. “We even supply
measurement solutions for space research,
for example for the Giant Magellan Telescope
and the CCAT radio telescope observatory,”
Dr. Heinrich Schwenke reports.

Eye-safe fiber-laser sensors are arranged on the machine-specific frame for capturing specificmeasurement lines that are needed to create a highly precise geometric image of the machine.

Etalon’s LineCal® is an innovative system which
considerably simplifies the calibration of measuring
and testing machines – not least, due to the industry oriented design and the sub-micron accuracy of
the IDS3010 from attocube systems.

The IDS3010 fromattocube systems AG
is the technologicalcore of Etalon AG’s
innovative LineCal®
interferometric calibration system.

IDS3010 – ultimate precision in industrial design
The IDS3010 interferometric, multi-channel displacement sensor opens up a totally new dimension
in precision in high-end industrial applications.
Positions and motions can be simultaneously measured in up to three axes with a digital resolution of
one billionth of a millimeter. One measurement isgenerated every hundredth of a microsecond. This
interferometric sensor easily surpasses the performance of any other presently available sensor technology. At the same time, the IDS3010 also scoreswith a concept that is perfectly aligned to industrial
environments: a space saving, integration-friendly
design, multi-channel capability, ease of use, data
output every hundredth of a microsecond and unlimited connectivity thanks to the integrated web
server with remote and Industry 4.0 connectivity as
well as real-time interfaces for standard industrial
networks and controllers.

Ideas in motion

No matter how much technology
moves forward, innovations arealways the doing of people – people
driven by passion and a pioneering
spirit.

“Oh, it’s the French lady from WITTENSTEIN!”
That’s how Fabienne Laville-Isabey, who actually holds dual nationality (French and Swiss),
is frequently greeted when she welcomes visitors to an exhibition stand somewhere out
there in the world with her delightfully charming smile. An employee in Marketing & Sales
at WITTENSTEIN motion control, she knowsfrom her many years of experience how important first impressions can be, even (or especially) where highly complex products are concerned like mechatronic systems for oil andgas exploration three thousand meters deep
down on the ocean bed: “When our innovations are unveiled to the public at a trade fair,it’s as if they’re my babies. And that’s exactly
how I describe them to visitors to our booth.”
She laughs, of course, as she says this. The
same goes for business contacts when she’s
working in the office: “They can picture theexpression on my face just by listening to me
over the phone.” Fabienne Laville-Isabey isconvinced that “a smile is always the shortest route between two people.” That’s the firststep completed: in the second, she hands theconversation over to her colleagues, the sales
engineers and designers. The conversation
then moves on to the technology.
Fabienne Laville-Isabey has an MBA in International Business and is delighted to be oneof the faces of the WITTENSTEIN Group’s
new employee campaign: “Ideas in motion –the slogan is a perfect description of what I

24 movedo, and I do it with passion and conviction. If
it wasn’t for the people, for the interpersonal
relationships that breed inspirations and ideas, there’d be no successful innovations.” To
Fabienne Laville-Isabey, it’s only natural thatshe should welcome her visitors in their own
language and respect their national customs:“There’s not much point in phoning someone in
Paris before half past eight in the morning; onthe other hand, nearly everyone in Norway has
gone home by four-thirty.”
Around 2500 people work for the WITTENSTEIN Group worldwide in the meantime; morethan 200 of them joined the company last year
alone, divided roughly equally between career
entrants and experienced experts. When Fabienne Laville-Isabey is asked to sum up what
it is that every employee should have in order
for a company like WITTENSTEIN SE to maintain its momentum and growth in the future,
she doesn’t have to think long for an answer:“Openness to new ideas. The products we sellaren’t mass-produced and our manufacturinglines aren’t fully automated. We develop customized solutions together with our users. To
do that, you need ideas and the courage to
explore new thoughts while they’re still only
half-baked. It’s always a win-win situation that
we’re aiming for. It’s particularly rewarding if
we can then show our products to the public
at a customer’s booth, built into that customer’s application. When a client honors us withan ‘invitation’ like that, we know we’ve made agood job of it.”Fabienne Laville-Isabey is one ofsome 2500 people at WITTENSTEIN
whose great passion contributes
to the development of customized
solutions in partnership with users.

Even closer to our customers worldwide
Sales Hub opens in Austria

Without the close cooperation between WITTENSTEIN and its customers, we would be unable to realize innovations together withthem and in doing so strengthen their competitiveness. These partnerships are essential to support the development of new machine
concepts effectively from the outset with new technologies and technical consulting. To further underline this closeness, WITTENSTEIN
is expanding at selected sales locations worldwide.
WITTENSTEIN GmbH of Leobersdorf, not far from Vienna, recently
became the first subsidiary to be upgraded to a Sales Hub; since falllast year, our Austrian branch has been offering extensive support to
the international markets. Local expertise has been developed andenhanced, with the result that project lead times are now shorter, as
is the time to respond to customer inquiries. It goes without sayingthat native speakers provide assistance to customers in their own
language as a crucial pillar of effective and targeted communications.
Established in 2001, WITTENSTEIN GmbH is today a reliable partner
for top companies in many different segments of the Austrian engineering industry. Owing to the central location, the firm’s eleven employees never have to travel extreme distances to project meetingsor seminars. And thanks to the regional reorganization of sales activities in the Czech Republic, Hungary, Slovenia and Slovakia from astrong base, customers are already reaping the benefits of our Austrian Sales Hub.

“We have very good relations with our eastern neighbors for historical reasons, and because the mentality is similar, and WITTENSTEIN GmbH is excellently
placed to develop those markets.
It’s a challenge we’re delighted to accept, and we’reconfident that we’ll enjoy considerable success inthese markets in the future!”Franz Luschnig, Managing Director WITTENSTEIN

Two customer statements testify to this: the collaboration between
Salvagnini Maschinenbau GmbH and WITTENSTEIN GmbH Austria
on low-backlash planetary gearboxes which began back in 2005 haslong turned into a genuine success story. At the time, manual toolchangers were used on small machines and servo hydraulic oneson larger machines; over the years, with WITTENSTEIN’s support,these have gradually been replaced by servo electric drive systems.
According to our Purchasing management, “The feedback from thecustomer was very positive and a massive increase in sales ensued
in the small machines segment”.
For many years now, WITTENSTEIN has supplied gearboxes andracks to TOS VARNSDORF a.s, the Czech machine manufacturer.
“Our corporate strategy is to work exclusively with well-known andproven European partners,” says Tomáš Jägr, a buyer. “WITTENSTEIN products satisfy our quality requirements in every respect andthe price is right too. There’s been many an occasion in the pastwhen mutual cooperation has been a big help in handling new projects. The support we receive from the Engineering department has
been particularly valuable.”“The overwhelmingly positive feedback from stakeholders left noroom for doubt that the reorganization was a success. That wasgood encouragement for us. We have plans to further strengthen
the collaboration with our customers in the long term by expanding more WITTENSTEIN sites. That will be our contribution to making them more competitive.”
