Riveting with extremely small dimensions

Riveting technology, like anything else, needs to keep up with the constant trend toward miniaturization. With the radial riveting machine RN 181 “reduced,” for delicate rivet connections, BalTec has a cutting-edge solution for this challenge, as well. The subtly designed kinematics of this machine allow rivet joints using even very small diameter rivets made of aluminum and fiber-reinforced plastics. It is possible to locate the rivet start when lowering the rivet tool onto the rivet at a riveting force of less than 0.1 kN.

New machine for microtechnology
The RN 181 “reduced” was developed on the basis of the proven RN 181 radial riveting machine. With a reduced piston area and extremely low-friction kinematics it is optimally designed for precision engineering rivet applications. The RN 181 “reduced” uses an RC-20A controller and the BalTec STF-1 Expert or RNC Expert process controller. This allows the rivet force rise, for example, to be limited to 0.5 N over a 0.5 second duration rivet phase, so that the riveting tool can still make at least four hypocycloid passes over the rivet even with very short deformation travel. The STF-1 Expert process controller ensures refined control of the riveting process and the highest quality rivet joint. The nominal riveting force of the RN 181 “reduced” is 1.6 kN, at a hydraulic pressure of 6 bar. The tool stroke is 30 mm. In addition to the stand-alone version of the RN 181 “reduced,” the rivet head alone is available for integration in systems, under the name RNE 181 “reduced.”

Typical application examples of the RN 181 “reduced”
Electronics and computer industry:
Mounting electrical circuit boards in aluminum housings with cast rivet features, or in plastic housings with molded-on rivet lugs, with rivet diameters of one to two millimeters
Production of measuring devices and clocks:
rivet lugs on indicator axes made of steel with diameters of less than 1 mm
Micromechanical devices (cameras, printers, automotive electrical components):
axes of magnetic armatures for servo drives, pivot joints, etc.
Joints, pivot pins in forceps, etc.

Is Eurotec TV planned for tomorrow?

To realize this editorial, I rely on two comprehensive studies on media. The first one called “trends in communication in Europe” is based and a wide European study that took place during 2008. The second called “Media Focus” analyze trends in advertising expenses in Switzerland. What do we learn ?

Press is important (!)
According to the first survey, in 2008 the customer represent the most important target audience (not that a revolution) for communication and obviously professional press plays a major role. Researchers responsible for the survey foresee a same importance of the target audience in 2011. According to that study, press is the main tool in 2008 and will still be a very important one in 2011, nevertheless, the online medium will be the most important one.
Clearly the online medium is a tool that we must think about. As for the paper media, the content is the most important.

Added value
Our role as members of the technical press is to look for, find, sort out, think about and finally give you a maximum of added value information (again that importance of the content). The second survey shows that in Switzerland the technical and professional press goes well. Advertising expenses are stable (more or less). All in all and for every field, the tool that goes bad is the daily newspaper that sees it figures plummet in favor of television and new medias.

Consequences for Eurotec
Will we soon see broadcast to buy the new “X” machine tool or the new “Y” tooling on Eurotec TY? Not likely would you say… but combining visual media and web, it is possible to show more, to explain more and even to interact. Let’s invent the future ! In any case content must be interesting for readers and help them a way or another, otherwise it channel-surfs quickly.
Our aim with Eurotec is to give you more value.. on paper today.

Issue 362 is on its way to subscribers!

A company that works with some nexialist principles?

I went to interview Pierre-André and Etienne Meylan in a company called Piguet Frères at Le Brassus, Switzerland and I didn’t stop thinking about nexialism. In that company, the skills are cleary interdisciplinary and transverse. You need some technique from highly specialised polishing of watch industry to finish a part for a medical device? No problem, functioning in the company allow the specialists to share all these skills and apply them on the right place, even if that’s not “the usual way”. Result? Good processes and better results for their customers.

Cold plasma – low pressure metal surface treatment

One of the main characteristics of the company is this will to always go further ad further to find solutions for their customers. For instance assembling some parts with a sticking technology needs a perfect state of the surfaces to be mounted. Piguet Frères master the cold plasma technology and the assemblies they are doing these days are far better than without that preparation… at such a point that their customer now gives them a lot more to assembly.
“In the microtechnique, we must be creative, we don’t want to do the same things as others do, we do want to give more to the customers to help them to go further too” – Pierre-André Meylan.

Don’t miss issue 363 of Eurotec!

Good day

PS: Issue 362 is ready, it will be posted tomorrow. Yeah! The fisrt one with the new concept, I’m eager!

PS2: For those who don’t know anything about nexialist, I recommend the excellent book by A.E. Van Vogt. Nexialist: One skilled in the science of joining together in an orderly fashion the knowledge of one field of learning with that of other fields.
He put the light on this “science” for his books called “Voyages of the Space Beagle” which is a very good book. An exploratory ship full of scientists visits planets far beyond the sun and other suns. The main character in the book is the only Nexialist on board and constantly struggle with the other scientists because they don’t consider Nexialism a “real” science. Needless to say, the Nexialist character is the hero because of his ability to pull together useful things from several different scientific fields.

Eurotec will be there to grasp what’s interesting for microtechnique.



Microtools need excellent clamping technology

The demand for ever smaller components in industry is constantly rising. Yet micromachining follows its own laws. Tolerances must be very tight. This places high demands on the machining tools. An exact run-out and repeatability of the processes are the keys to success. The user can achieve this with the new Rego-Fix ER microsystem. This innovative tool clamping system offers the overall system very high run-out accuracy and optimum vibration dampening.

A decisive effect
The Rego-Fix ER microsystem was specially developed for high speeds on new generation CNC processing centres, and ensures ultra-high precision and excellent results in micromachining. One example of this is the tool manufacturer Fraisa from Bellach (Switzerland). Stefan Senn, application developer at Fraisa said: “In the overall system, every component in its special design is crucial to success. There is no point in using a high-performance tool if the clamping and machining system does not offer an equally high-quality performance. This means that the clamping tool has a decisive effect on the outcome of a process. This is particularly true in the field of microtechnology because high run-out quality and the reproducibility of the processes are of paramount importance here.”

2 microns that make the difference

Fraisa was looking for solutions for a new microsystem in this area. The tools with a 3-mm shaft diameter overheat during shrink-fit operations and their run-out cannot be guaranteed.
Michael Hirschi, a Fraisa ToolSchool employee: “A precise run-out is absolutely essential for the tool life. For example, if run-out accuracy is equal to 2 µm, I drill up to 10,000 holes using a drill with a 0.8-mm diameter, even a large feed rate. However, if the run-out is higher than 4 µm, I can only produce a couple of hundred holes!”

Balanced at 25’000 min-1

The special design of the Rego-Fix micromilling system allows the user to work with the ER MS clamping nut, which has been specially designed for ultra-high speeds. This clamping nut features finely machined contours on all sides, and this results in minimal residual unbalance. Because this nut does not feature a pull-out shoulder, the collet is pulled out by means of the special E MS type wrench.
It even ensures ultra-high run-out accuracy and minimum residual unbalance at the maximum speed of 80,000 min-1. Henning Neumann, Head of European Sales at Rego-Fix AG add: “The tool holders are balanced at 25’000 min-1 in G 2.5, and the system is much more precise than the competition because all Rego-Fix components are designed to work in perfect harmony with each other.”

Comprehensive tests
The tests performed by Fraisa focussed on noise factors, optimum cooling, accuracy of the overall system’s run-out and minimum play of the spindle. Different materials and vibration behaviour of the overall system were also fully tested. The results of the precision of the Rego-Fix microsystem were even better than expected.

“This short news emphasizes another technical high precision device from Switzerland. It seems that this area of the world is really in the center of the world of microtechniques.
Is it true that people there have the micron at the top of the fingers?
I don’t know but what I know is that there are a lot of companies bringing good solutions to the market of high precision machining… and with Eurotec they have a magazine to help them communicate.
