They move the drums in printing machines and rotate antennae in the desert – even though the screw jacks from this drive specialist are very different, they all have something in common: they must meet high standards for precision and reliability. But high wasn't high enough for Managing Director Martin Kirchmaier back in 2013. He also wanted to accept orders even from the most safety-critical industries and decided to further increase the accuracy of the company's gears. He invested not only in a new machine tool, but also set out to find a coordinate measuring machine that would enable him to verify the precision of his products.
Up until this point, the gear manufacturer had only used the integrated measuring technology of the machine tools in combination with a manual horizontal arm measuring machine and measuring equipment such as gages and slide gages. Kirchmaier now opted for the ZEISS ACCURA coordinate measuring machine. To ensure that the highly precise measuring machine performed at its best, the Managing Director also invested in a climatized measuring room. Now incoming goods inspection, first-piece inspection, random samplings and final inspection are nearly all performed on the measuring machine. The same applies to the 100% inspections of the gear components with demanding standards, such as those for use underwater.
Compared to the former method involving manual capture of the quality characteristics, ALBERT has clearly shortened its measuring times. Above all, however, the higher precision of the machine offers the design and production staff greater certainty. They can now better assess the accuracy of their work and then perform any adjustments required. Kirchmaier, the Managing Director, is pleased: "We now have a new understanding of quality – and can even provide the highly complicated documentation for nuclear technology." Kirchmaier's farsightedness has paid off: With the aid of the new measuring machine, he has received an order for gate drives at a British nuclear plant.
