Precision tools, accurate lathes and a deep understanding of how to use the two to achieve micron precision. This describes the cooperation between Paul Horn GmbH, the machine manufacturer INDEX and the contract manufacturer of precision turned parts, RICH Praezision. "The proximity of all three companies to one another and the long partnership between us can be described as a success story," says Wolfang Rich. He and his brother Gottfried manage the company RICH Praezision as third-generation directors. RICH Praezision has relied on tool systems from HORN since the 1980s. The company is a customer of, as well as a supplier to, the Tübingen-based tool manufacturer.
