In the automotive industry, technical surfaces tip the scales when it comes to high-precision mechanics and their performance. The dimensional tolerance has a decisive influence on a product’s fuel and energy efficiency, eco-friendliness and durability. From sealing surfaces, to the drivetrain and shock absorbers and to injection systems, there are a multitude of applications “being put to the test”. Absolute precision when contactlessly determining flatness, parallelism, form parameters, surface parameters, heights and steps is vitally important. And what should you use to ensure this? The surface measurement systems from Polytec, of course!
