automatic loading of machine tools and it stands for utmost productivity. Thanks to a rotary traveling column, the grinding direction is adjustable to the helix angle of the steering rack. This means that axis travel paths are considerably shortened compared to conventional machining. The design of the new MÄGERLE machine is correspondingly compact. It has two working areas with a movable splash guard cabin and thus facilitates loading and unloading of workpieces during the machining cycle without downtime. The machine’s traveling column is particularly heavy. During the design of the drive control, the development engineers were pushing the limits of technology: ‘We had to exploit the full potential of the Siemens control system,’ explains Martin Preisig, Technical Manager at MÄGERLE. When designing the drive for the transversely positioned, high-performance grinding wheel drive, the engineers relied on a calculation tool for verifi cation. They also implemented a customerspecifi c user interface that is specifically geared towards gear grinding. The tooth forming angle can be programmed individually and the machine measures the graduation precision automatically. The customer can now benefi t from maximum productivity and flexibility – even when grinding oversized steering racks.

` Nuts of large threaded spindle drives With thread grinding, MÄGERLE entered uncharted territory and during the development of the MÄGERLE MGC-L-140.50.90 it had to overcome two enormous challenges for operator-friendly complete machining of nuts of large threaded spindle drives. On the one hand, the most extreme accuracy requirements had to be met and on the other hand, the complexity of the workpiece had to be taken into account in the operator software and the man-machine interface in a way that guarantees maximum user-friendliness. The result is a specialized machine that grinds the internal and external diameters of nuts as well as threads absolutely concentrically and can machine surfaces at the same time. ‘Although the necessary swiveling spindle protrudes a very long way, our development

The long road back to normality Prof. Thomas Straubhaar discusses the world economy since the crisis in the financial markets.

irst the good news: things are looking up again. The bad news is that the

recovery is sluggish, it has a low level to start from and it is (still) not really selfsustaining. Last year, the economy went straight down to rock bottom at high speed. Now it is making its way up again, step by painful step. The best that we can hope for in 2010 is to get halfway back, but it is more likely to be only a third. It may be years before we are back at our pre-crisis position and have reached the full exploitation of capacity that prevailed in 2008.

General: In Mexico, successful business deals are built on good personal relationships. Try to gain the sympathy of your business partner before getting down to business. Mexican punctuality means not arriving until at least 15 minutes after the agreed time. Formulate criticisms carefully and don’t get personal if things don’t go your way. Knowledge of the local language will earn you Brownie points. Even if you speak only a few words of Spanish, you will certainly make a favorable impression.

Greeting: Men shake hands on meeting. Women usually greet each other with a handshake and a kiss on the cheek. This type of greeting is not uncommon even between men and women.

Body language: Putting your hands on your hips or in your pockets is seen as impolite.

When clamping becomes critical … Extraordinary applications demand extraordinary solutions. Many workpieces cannot be properly clamped by virtue of their unique characteristics. We develop targeted customized chucking systems.

Eating and drinking: If you are invited to a private meal, you should wait to be shown a seat before sitting down. A polite guest always leaves a little bit of food on the plate. Restaurant guests are expected to leave a tip. The usual amount is ten to 15 per cent of

FROM APPLICATION

` Meeting place and platform In very close co-operation with its industrial partners, inspire generates know-

Polymer concrete: For the past 30 or so years machine beds and also some components have been produced in polymer concrete. STUDER was one of the pioneers. The advantages of polymer concrete are better damping, faster availability and a more attractive price. Designing the material for long-term performance and creating structures for mounting and connecting to other components present considerable challenges. The Institute sees great potential in design engineering that is appropriate for the material involved. EGT: The idea behind engineered grinding tools (EGT) is to produce a grinding tool with superabrasives and with substantial grain height over the bond and a large chip pocket. A chemical bond is needed to ensure that the grains adhere sufficiently to the substrate. An active brazing process ensures this. Because of the heat transfer problem due to different conduction coefficients of grain and substrate material, the process chain as well as suitable materials have to be carefully selected to achieve a good accuracy. The tools must be designed in such a way that the grains can absorb the grinding forces. At the same time sufficient chip removal and cooling space must be provided together with acceptable surface roughness.

how and research results that are used directly for new products and processes. ‘In production technology, research is only profi table when it is implemented in industry,’ says Professor Wegener. With its cooperative networking and events with industry, inspire is also a hub and platform for production and manufacturing technologies of the future. Since its establishment in 2004 the Institute has been working together with the SCHLEIFRING Group, among others. STUDER, for instance, has made a cylindrical S31 grinding machine available to the Competence Center. The researchers mainly use metal-bonded grinding wheels with superabrasives when working with this grinding machine. The focus of the research is to work on diffi cult-to-machine materials such as oxide and nitride ceramics. There are also interfaces to MÄGERLE and EWAG. Together with other industrial partners, MÄGERLE and STUDER participated in a research project for

With EWAG and STUDER, the Institute is researching on a hybrid grinding process in order to machine the diffi cult-to-machine materials easier and more effi cient. inspire is developing and testing new methods and components for grinding machines.

TOOLS & TECHNOLOGY

` New dressing unit A highly promising process is Wire Electrical Discharge Dressing (WEDD). Metal bonding is predestined for grinding tools with superabrasives because of its tight bonding to the grain and its good thermal conductivity. However the application of such bonding is restricted due to the diffi culties in dressing. A new dressing unit based on wire erosion has therefore been developed on a STUDER S31 cylindrical grinding machine, enabling on-the-machine dressing. Since this dressing unit has two independent moveable axes, it can be used to dress the grinding tool parallel (simultaneously) to the grinding process. Wire erosion allows practically any desired contour to be produced without the need to rework the electrodes. This is continually regenerated by feeding the wire longitudinally. Precision is achieved by constant wire feed speed and accurate guiding of the wire. In the project, the grinding process generating the part has precedence. The erosion dressing is subordinate to it. In

The next best thing to flying Renato Pfeiffer holds an unusual title: he is the European remote control glider aerobatics champion. The STUDER electrician devotes all his spare time to his expensive hobby.

Perfect conditions: Blue sky and sunshine

Aerobatics: The red smoke trail draws figures in the air

T

he clear blue sky and light breeze offer the best possible conditions

for a remote control glider aerobatics championship. Around twenty contestants are waiting at the edge of the airfield to launch their homemade aircraft. Bravely, Renato Pfeiffer takes up the remote control unit for his model glider. He takes a deep breath, hooks the tow rope onto the towing plane, and the glider with its 5.6-meter wing span starts to move. The plane and glider are flown up to an altitude of 500 meters, while Pfeiffer watches on intently. The towing pilot gives him the signal to unhook the tow rope. Now acro glider SoloFox flies on its own without power. Although the glider has launched successfully, Renato Pfeiffer carries on staring intently at the sky over Switzerland. He has been practicing for months for this moment. Now he needs to perform the aerobatic figures without any mistakes. ‘The worst thing that can happen is that the glider does not fly straight. That means that it has a constructional flaw,’ says Pfeiffer (40), a Swiss national. In that case, months – sometimes years – of work will have been wasted. But luckily, Winners: Renato Pfeiffer (left) and Tim Schärer proudly display their acro gliders and trophies

thrilled the very first time he took the controls, but fl ying the models is not everything: ‘It’s a complex hobby. Every stage builds on the one before – from building the models to practicing and taking part in competitions,’ Renato Pfeiffer explains. ‘Working with the different materials like wood, fiberglass and Kevlar fiber, and programming the controls provides constant challenges,’ he adds.

Model flying involves a huge number of different acrobatic elements, and the fl yers are expected to know all of them. ‘I have to be able to do all of the figures. And if I can’t, I practice until I can do them in my sleep,’ says Renato Pfeiffer. ‘In competitions, the freestyle part needs to be as varied as possible.’ He practices loops, rolls and

flick/snap rolls. Figures in which the wings do not support the glider (e.g. spins, stall turns and snap rolls) are particularly challenging. Sometimes a demonstration includes some very slow fl ying. Pfeiffer has to focus all his attention for this. ‘If the figures have to be performed low over the ground, there is a high risk of crashing,’ he says. But it is not for nothing that Renato Pfeiffer is European champion. The last time one of his models crashed was four years ago: ‘It hurts, of course, when months of work are wiped out in an instant. But we learn from our mistakes,’ he says. His next challenge will come in the spring, when he will be competing against people in the highest category – the international sports class.
