Quality inspection on precision mechanics
Both the surface quality of compensating discs and the pistons are crucial in shock absorber development if a quality product is to be created. That’s because pistons and compensating discs are key components for correct shock absorber function. They control how a shock is absorbed, since they act like a valve for the liquid or gas inside. Form deviations outside of defined tolerances at moving parts’ contact points may lead to leakage. Precise control and monitoring in the manufacturing process is essential if the targeted absorption effect is to be guaranteed. Both of these tasks are simply inconceivable without production measuring technology. Tactile surface metrology methods used to detect these shortcomings are very time-consuming and only provide an illustration for part of the surface.
