To work where it’s nearly impossible

In all areas, users of machines-tools, whether turning or milling, seek solutions to machine more effectively, to place tools in reduced spaces, or also to increase the number of tools available in fixed kinematics. The answers to all of these needs are precisely the forces of Pibomulti/Emissa (Switzerland). Meeting with Mr. Pierre Boschi, director and owner of the company, for whom nothing (or almost) is impossible.

The new patented Pibomulti system is ideal for machining in places hard to reach.
The new patented Pibomulti system is ideal for machining in places hard to reach.

On the occasion of Midest Paris, on the ‘special machines’ village, the manufacturer will present many innovations. Mr. Boschi says: “Midest is an important trade show for us. Numerous subcontracting players of the areas we cover, namely automotive, aeronautics, hydraulics or electronics are present and we can give them specific examples of improvements of productivity and/or machining conditions”. We will see a few of those innovations in the following days.

Angular machining in a small footprint
In the field of aeronautics for instance, many parts require angular holes near the walls where it is almost impossible to bring a tool. The new angular tool-holder allows holding a diameter 6 mm drill with a distance of 3.5 mm between the outside of the tool holder and the center of the tool. Despite a wall thickness of 0.5 mm, the tool is driven up to 12’000 t/min. and guarantees a couple of 0.8 Nm. Mr. Boschi says: “We had to find technical tips to ensure rigidity. There is no ball-bearing and no guide-bush, the tool is held directly into the tool holder”. This attachment system does not require pre-heating or complicated device and it is suitable for all types of tool holders. It guarantees the set-up of rotating tools repeatedly within 2 µm.

Out of standard potentials improvements
In all areas, from microtechnology to boat motors, Pibomulti/Emissa original solutions bring more to users. Mr. Boschi gives us an example: “At the EMO we were approached by a well-known brand of phones which realises micro-machining operations on small forged parts. The current cycle time is 20 seconds, using our developments made for the watchmaking industry, we are able to produce the same parts in 3 seconds”.

To be discovered at Midest Paris from November 19 to 22, 2013 on booth 6F92.

The new patented tool-holding system brings large machining capacities in a small footprint. Typical customers are from aerospace, automotive and hydraulic industries.

Cryogenic cooling reduces wear and tear

The boom in giant aircraft, particularly, is driving a radical transformation in the materials of choice: suddenly, titanium, nickel-based alloys, ultra-high-strength steels and carbon-fibre composites have to be machined on a large scale and at high levels of productivity.

Metav 2014 will showcase prospects for new cooling strategies
Conventional cooling lubricant concepts often come up against their physical limits here. The potential of cryogenic cooling compared to conventional processes has been rigorously examined by Hendrik Abrahams, a scientist on the staff of the Institute of Machining Technology (ISF) at Dortmund Technical University.

Cryogenic cooling: a genuine trend
Hendrik Abrahams  says: “The aircraft industry has a significant demand for more efficient processes and, from a researcher’s viewpoint, we’ve identified the salient advantages of cryogenic technology as an option for upgrading productivity levels”. The interest is there: as evidenced by Premium Aerotec GmbH, one of the sector’s leading component suppliers, which has already purchased machines featuring cryogenic cooling and is trialling the technology concerned.

Cryogenic cooling will pay off
The cost-efficiency of cryogenic cooling depends on the CO2 consumption. “To reduce the costs for carbon dioxide consumption, we’ve already conducted studies on how to downsize consumption, where we’ve proved that with a significantly reduced CO2 mass flow – to be precise from 2.7 to 0.6 kilograms per minute – machining can be performed with equally good results. When the CO2 consumption is optimised and reduced still further, together with significant gains in productivity, it can be assumed that cryogenic cooling will pay off” concludes Abrahams.

When the machining process makes the difference

For many specialists working with machining companies in France and Europe, the name of Huron is a little part of the past. It is the brand of the machine on which they learned. It is always there and one may think about it with nostalgia, but seldom with a clear vision of what it is today: a dynamic manufacturer who offers extraordinary machines and machining processes. Meeting near Strasbourg with Ms. Labeauvie, Marketing Manager and MM. Echevard, CEO and Lutz, commercial Director.

The new premises of Huron in Eschau (Strasbourg, France) is fully air-conditioned and currently hosts three lines of products made according to the principles of Lean manufacturing. The company covers nowadays 12'000 m2 in Illkirch and 8'000 m2 in Eschau. Additional 12,000 m2 are planned in Eschau (2016-2017).

The company covers nowadays 12,000 m2 in Illkirch and 8,000 m2 in Eschau. Additional 12,000 m2 are planned in Eschau (2016-2017).

During the visit of the assembly workshops, what immediately grasps attention is the dimensioning of elements of machines. Ball screws, linear guides and castings seem to be largely oversized when compared to the usual standards of the market. Mr. Lutz confirms: “The stiffness is the first asset of our machines, everything is very widely dimensioned. They are very sturdy, reliable and accurate”. This strategic choice obviously directly affects all design, engines, hydraulic systems, everything is “large”. Is this not of luxury? The CEO say: “Absolutely not, this is what makes us different and has allowed the continuous growth of our turnover for several years”.

Two examples of extraordinary results
The company is full of examples which seem invented from scratch because of extraordinary results. M. Echevard says: “I was visiting a car manufacturer and seeing a machined camshaft, I assumed they were machined in about twenty hours. After discussions with the client, he told us they needed a little bit more than 90 hours to finish it. We analyzed the part and optimized the process on a Huron machine and offered the solution. We were able to produce the part in 17 hours” thus a gain of more than 80%. Another example, a microtechnology complex assembly requiring 100 hours of machining and the assembly of 7 components is carried out today at the customer’s on a Huron center in one piece, it requires approximately 8 hours of machining, and is totally finished on the machining center.

Dynamic turbine wheel on TiAl

SWSTech AG takes pride in solving ingenious technological challenges in the production of components. The example presented here is a new turbine wheel in titanium aluminide (TiAl) produced by the company.

Free of chlorine and heavy metals, the Ortho NF-X oil guarantees a perfect treatment of highly alloyed steels or implants steels but also non-ferrous metals and aluminum. It is an entirely new phenomenon in modern manufacturing techniques. This universal usage has also been verified during machining of the titanium aluminide turbine wheel and constituted a factor of success of this project.
Free of chlorine and heavy metals, the Ortho NF-X oil guarantees a perfect treatment of highly alloyed steels or implants steels but also non-ferrous metals and aluminum. It is an entirely new phenomenon in modern manufacturing techniques. This universal usage has also been verified during machining of the titanium aluminide turbine wheel and constituted a factor of success of this project.

If most thermally exposed exhaust gas turbochargers’ turbine wheels were, until today, cast and finished by machining, they are nowadays more and more often realized by CNC milling in new lighter materials.

Innovative  project
In the automotive, industry and more particularly in motorsports, the relatively high density of turbine wheels (8.5 g/cm³) and the resulting rather passive behaviour of the turbochargers have always been a source of annoyance. Dynamic researchers have succeeded in developing a new titanium alloy that is close to nickel based alloys in regard to resistance to high temperatures but whose density is much lower (3.8 g/cm³).

SWSTech AG equipment enables the manufacture of prototypes of milled turbine wheels that are usually cast in nickel-based alloys, a tedious operation. In the current project, the wheel is milled in a single operation from titanium aluminide, a high-tech material difficult to machine. The rotor without central bore is firmly tight on a Hermle 5 axis machining center by an automatic process. All operations can be machined within an optimal cycle time thanks to the excellent accessibility to the part.

Multifunction cutting oil
During the various milling operations, the Swisscut Ortho NF-X 10 universal high performance cutting oil of Motorex has fulfilled several functions that played a decisive role in the outcome of machining: hard chip evacuation, cooling of the tool and the machined part, development of a lubricant film between the blade of the tool and the workpiece and surface protection of the part.

Micro-mold… and much more!

For years it seems that manufacturers have been developing tools that are ahead of the capacities of the means of production for which they are intended. With its 701S machine, Willemin-Macodel gives them room to think and innovate.

Benefitting from an original design that ensures accuracy with low masses, a wide dynamics and flawless trajectories monitoring, the 701 S machine forces to rethink certain principles, notably that mass equal precision.
When talking about micro-machining, special phenomena occur at the level of the “tool-material” couple. Before the launch of its new machine, Willemin-Macoodel worked closely with Louis Belet SA to offer very advanced tools taking into account the performance of the machine.

Indeed, this micro-machining center unveiled at the EMO is able to push the capabilities of the tools to their limits, thus providing manufacturers of tools a new field of action. Meeting with Mr. Denis Jeannerat, Technical Director and Anne Hirtzlin, Communications Representative at Willemin-Macodel.

A star is born at EMO
True highlight at the last EMO, the 701S  generated many discussions in Hanover, particularly in the fields of watchmaking and micro-mold. Ms. Hirtzlin says : “At Hanover, we received very many concrete requests; potential customers came to discover the machine with immediate needs”. Mr. Jeannerat continues : “Customers were very receptive, the machine is totally in accord with the parts they want to produce”. And if the kinematics and the delta architecture of the machine are completely different from habits to ensure very high precision (huge masses), as soon as they speak “tool and chips”, the specialists are convinced. So all planned machines for this year has been sold in September.

An impossible machine a few years ago
To ensure the high precision announced (trajectories accuracies below one micron), the machine works fully by interpolation, which means that all paths are recalculated constantly, control loops must be fast and only a powerful PC can deal with it. Mr. Jeanneret  says : “This computing power coupled with high resolution measuring rulers (less than 10 nanometers) allows us to guarantee submicron precision. The embedded PC is widely solicited”.

We will detail a few more aspects of this machine in Eurotec’s next issue:

  • Target: injected parts of a few milligrams
  • The benefits of 701S micro-machining: precision and quality
  • The benefits of 701S micro-machining: speed and efficiency
  • New strategies, new tools
  • Working in collaboration with the manufacturer to provide…
  • … tools developed for the machine
  • New approach to machining

.

With tools of a few tenths of millimeters in diameter, the precision of paths must be absolute. The scale of this image is of one micron between each line. The red contour represents the path of the tool. Stunning!

Italian-designed smartphone breathalyzer receives Cool Idea! Award

Floome is an  elegant and practical universal smartphone accessory developed with the help of Proto Labs that provides users with accurate and reliable blood-alcohol readings. It has joined the ranks of some of the most promising hardware innovations as a Proto Labs Cool Idea! Award recipient.

Floome is a universal smartphone accessory that provides users with accurate and reliable blood-alcohol readings. Its realisation was greatly simplified by Proto Labs Cool Idea! reward programme.
Floome is a universal smartphone accessory that provides users with accurate and reliable blood-alcohol readings. Its realisation was greatly simplified by Proto Labs Cool Idea! reward programme.

Proto Labs launched the Cool Idea! Award in 2011, which gives a total of $250,000 each year to entrepreneurs developing new products in the United States and Europe. Unlike other product awards that recognize products after they’re in mass production and on store shelves, the Cool Idea! Award is meant to help cool ideas come to life. Proto Labs provided the Floome’s co-founders, Marco Barbetta and Fabio Penzo of Italian company 2045Tech, with tooling and a subsequent first production run of injection molded parts.

User-friendly and efficient
“Floome is the first, reliable smartphone breathalyzer,” says Barbetta. By blowing into the device while it is connected to a smartphone audio jack, the users Blood Alcohol Concentration (BAC) is measured. Floome employs a patent-pending technology that matches a vortex whistle with the fuel cell ethanol sensor that is widely used by law enforcement breathalyzers. The collected data is sent over audio frequencies to the corresponding app where the user can view their BAC, get an estimate of when they will reach the legal limit to drive based on their test results and body characteristics, set an alarm to take a new test, view a graph of previous results, or call a nearby taxi.

From original design to production thanks to Proto Labs
For 2045Tech, the casing design for Floome was as important to its overall functionality as the technology inside it. “After many sketches and prototypes, we came up with a really unique, eye-catching shape; its smooth edges and lightness also make it easy to carry around,” says Barbetta. “Receiving the Cool Idea! Award has enabled us to move from the testing stage into production, which is a big hurdle for any new product,” says Penzo. Adds Larry Lukis, founder of Proto Labs, “Floome eliminates the predicament many find themselves in while out for a drink; it provides an accurate and at-the-ready means to determine when they are safely able to drive. Combined with its elegant design aesthetic and smartphone integration, this cool product should be a great success.”

Laser system trade fair for industry off to a flying start

Laser systems for material processing will once again be the focal point of LASYS 2014, which will be held at the Stuttgart Trade Fair Centre from 24 to 26 June 2014. One year before it is due to start, more than 70 exhibitors – including some important market leaders – have already registered for the international trade fair for laser material processing.
Lasys_Eurotec
They will present, at the only international trade fair for laser material processing, innovations in the fields of separating, joining, marking, labelling, changing of material properties, coating, casting, reshaping and hybrid processes. Special attention will be paid to the new topics of laser additive manufacturing and robotics and automation.

Additive manufacturing, …
Using laser-based additive manufacturing, it is possible to produce almost ready-to-install, customised components made of different materials such as metal alloys, plastic and composite materials, or ceramics. The new pavilion “Laser additive manufacturing“ will take a closer look at current developments and trends in the manufacture of components and products.

…robotics and automation…
The robot is an important tool for efficient, fast and economical use of laser material systems. It is the ideal partner for the non-contact and wear-free laser. The “Robotics & Automation Area“ at LASYS will feature solutions for automation of lasers using industrial robots.

…for the industry
The range of topics will be specifically addressed at industrial users. Out of the total number of 5,293 visitors at LASYS 2012, an impressive 76 per cent came from industry, primarily from mechanical engineering, motor vehicle construction, electrical engineering and electronics, metal working and processing, and plant and apparatus construction, i.e. the core target groups for laser material processing, but also from many other sectors. Visitors will also find highlights from production engineering at the congress “Stuttgart Laser Technology Forum (SLT)”, which will be staged concurrently with LASYS by Stuttgart University.

Parallel events
Other attractive trade fairs will take place at the same time as LASYS 2014: the UKIP automotive trade fairs Engine Expo, Vehicle Dynamics Expo, Global Automotive Components and Suppliers Expo, Automotive Testing Expo and Automotive Interiors Expo. O&S, international trade fair for surface treatments and coatings, and parts2clean, leading international trade fair for industrial parts and surface cleaning, will also run in parallel with LASYS 2014.
