Leitz CMMs with QUINDOS test the accuracy of engine components for one of the largest engine plants in the world

Autobahn signs can already be seen some 1,5 hours Southeast of the Vienna city lines announcing the famous four interlinked rings. Immediately a vision pops into your mind: a sporty Audi racing through the spectacular landscape, hugging the passing curves of the hilly, serpentine and perfectly smooth asphalt. A part of this image your having is created by the subsidiary company AUDI HUNGARIA MOTOR Kft., which can be found in Hungarian Gyõr, close to the Austrian border. Over 1,9 million engines were produced here for various models of the Audi and VW Corporation in 2008. The quality assurance of the complex engines is amongst other things, measured on a total of 19 high-precision Leitz coordinate measuring machines.

Twelve Leitz SIRIOs, three Leitz References, three Leitz PMMs, one Leitz PMM-F – the list of the coordinate measuring machines that can be found in the measuring rooms of the Hungarian subsidiary company reads like an encyclopaedia article written on the Leitz brand. The youngest member of the Leitz machinery: a Reference with an integrated rotary table.

A little less than 400 engine varieties are produced at Gyõr. Amongst these are for instance, the R4 engines, or the so called Global Engine, a 2 litre turbo FSI engine. However the biggest power packs of the corporation are also manufactured here: the V6, V8 and V10 engines, and now also quite recently, the V12 diesel engine – which is the heart of the Q7 model. All of the main engines are produced in Hungary. The spectrum spans from engine blocks and cylinder heads to piston rods and up to crankshafts and camshafts.

In the future, more engines will be equipped with the new camshaft generation, the Audi Valvelift System (AVS). This is a new challenge for Audi: between 2008 and 2009 as well as from 2009 to 2011, Audi will double the quantity of this new camshaft generation, not only because of the enormous amounts to be produced but also the fact that the new camshafts are very complicated parts to manufacture and require the full 100% commitment and performance of man and machine. Gearing, cams, mountings, axial control grooves are all found in one single unit. At the moment this feature of continuous testing in one sequence is only possible with coordinate measuring machines. Leitz measuring systems achieve these unusually high demands seven days a week, in three shift operations . . . . .
