The best production measuring technology for more than 90 years HAFNER has worked in the field of production measuring techno ... logy since 1928. Our core competency is the development and manufacture of special measuring devices ranging from manual measuring stations to fully automated measuring machines. We are experts when it comes to tactile, pneumatic and optical measuring technology as we are with the inspection of hardness, cracks and surfaces. Weighing, marking and sorting are also elements of our complete systems. The measurement of all linear measures (height, thickness, groove/web width), form (concentricity, parallelism, angle) and position tolerances (dimension between axes, drilling position and symmetry) are central tasks of our measuring systems. read more
