Time Savings and 100 % Repeatability

You would not necessarily expect to find a factory where companies such as Ferrari and BMW come and go in a continuous stream in Pyrbaum, a village of 5,500 people to the south of Nuremberg. The quality of the components, which 130 employees produce in a manufacturing facility in the middle of an inconspicuous industrial estate, is what attracts the designers of high-speed cars – and also of aircraft and nuclear power stations – to the Upper Palatinate. The company is called Müller Präzisionsteile GmbH and the name basically says it all - Präzisionsteile means precision parts in German.

Stephan Müller, son of the company founder Georg Müller, is in his element during the factory tour. There is the camshaft for Audi with two cams per valve which can be shifted, thereby giving the engine a different power characteristic. Even the layman can see that the shaft with the movable sleeves has to be manufactured with extreme precision, so that nothing jams here.

Müller is most proud of the Quality Assurance Department. It provides a complete measurement record for each part which leaves the factory. The record is stored for at least ten years, even 25 years for components for nuclear power stations. The customers would not even have the possibility to document the high precision, and they rely entirely on the records, Müller says proudly. The five coordinate measuring machines from ZEISS Industrial Metrology make a major contribution to this. They consist of a ZEISS ACCURA, a ZEISS O-INSPECT and three ZEISS PRISMO, two of which have a rotary table. The employees work in two shifts, the measuring machines often around the clock; lengthy measuring programs run at night.

Because the Quality Assurance Department cannot allow a standstill, it looked for a solution which makes changing the probes as smooth as possible and also found it with the FixAssist VAST from ZEISS Industrial Metrology.
