As long ago as 1930, Dr. Johannes Heidenhain formulated the three principles of Service to the customer, highest achievable quality and continuous improvement as prerequisites for our company's success. To this day, these principles remain the basis for our work and actions. The requirement for highest achievable quality refers not only to the final products, but also to all activities in our company. The high HEIDENHAIN quality standard has been confirmed by certification according to ISO 9001.
