Use of low-frequency air springs Measuring machines are a tricky business. The smallest inaccuracy will lead to unusable results. Which is why ambient vibrations that could be transmitted to the system must be isolated at all cost. As a full-range supplier from design to distribution, the Hungarian company Semilab provides a great variety of measuring techniques. The measuring portfolio ranges from the characterization of semiconductor and photovoltaic materials through to production process monitoring, for semiconductor components and solar cells. The complexity of this range of solutions is a measure of how well this Budapest-based enterprise is handling it. Most of these technologies can be integrated in various platforms. Over 70 physicists and 90 engineers around the world ensure an extremely high quality standard. Further reasons for success: most Semilab measuring techniques are non-contact and non-destructive. The installation of a glass measuring table was nonetheless beset by difficulties. The glass measuring machine had originally been equipped with isolators that worked very softly in the horizontal axis. The relatively low lateral rigidity of the products used led to low internal damping of the isolator and permitted the machine to start vibrating when subjected to dynamic shocks or additional accelerations. The measurement errors resulting from these undesirable motions meant that the problem needed to be remedied as quickly as possible. Semilab hence lost no time in beating a path to the door of Norbert Turi at the Hungarian BIBUS branch. And as they had hoped, Norbert Turi, long-standing sales engineer at BIBUS, a leading supplier of hydraulic, pneumatic and mechatronic technologies, quickly came up with an answer. In order to offer Semilab the best solution available at the time, he also took ACE Stofssdampfer on board, the innovative component supplier and BIBUS cooperation partner. But this was not the end of the trail to a successful solution, because wherever vibration isolation and damping is concerned, this company from Langenfeld in Germany in turn puts its trust in a close cooperation with its sister company Fabreeka GmbH from But-telborn in the German Hesse region. In this case the ACE expert for vibration technology, Dieter Wohlschlegel, teamed up with his colleague at Fabreeka, Axel Platen.
