Five workshops of the DEUTSCH BAHN AG utilise DEUTROFLUX testing systems for the inspection of railway axles. Initially, the axles undergo a surface machining. Afterwards the axles are tested for surface cracks. Finally, the wheelsets are re-assembled. The circular magnetization for longitudinal defects is produced by a direct current which flows along the axle. The detection of transverse defects is based on an axial field which is produced by a moving coil. The moving coil can operate (coil movement, ink spraying, magnetization) in both axial directions to reduce the cycle time. A motorized roller support turns the axle in both circumferential directions for a convenient visual test. An automated motorized adjustment of the clamping length, a link to the higher-ranked PC-network and the automated supervision of the test liquid using the patented FLUXA-Control are some of the possible options.
