Crack and grinding burn testing on rolling elements with ELOTEST PL600
Eddy current testing integrated into a fully automated STALVOSS testing system
Bearing rings and rolling elements are widely used nowadays. In order to ensure the consistent quality of the parts, they are 100 percent tested and documented.
The fully automated STALVOSS systems perform contact free and quick non-destructive testing by means of eddy currents. The digital testing instrument – ELOTEST PL600 – from Rohmann is used in these systems. ELOTEST PL600 with its two-channel structure evaluates the eddy current signals from two stations independently from one another. An 8-fold multiplexer as well as a 4-fold array and one single sensor are used for the tests at every station for the detection of cracks and grinding burns on the surface and face areas of the rolling elements. The cycle time is approx. 1.2 seconds per part.
