During bending and straightening of hardened steel shafts, some components crack. Some cracks close at the surface. Thus they are invisible for subsequent test methods.
If a component cracks, it emits a characteristic signal. With the new acoustic emission analysis HFIM, a highly selective Crack Detection becomes possible.
QASS Optimizer4D reliably detects cracks and minimizes false reject rate. The measurement system is able to discharge faulty components automatically.
