Fluorescent magnetic test machine supports manual and semi-auto modes controlled by imported PLC. Manual mode runs each function step by step separately. Auto mode executes built-in PLC programs automatically. After manual loading, it completes clamping, rotation, spraying, magnetization, inspection, demagnetization and unloading automatically. Superimposed magnetic field shows all-direction marks at once for high testing efficiency. This machine features high automation, fast test speed, low operator workload and stable performance. It complies with standards GB/T 15822, NB/T 47013.4, ISO 9934, ASTM E1444.
