CJW666 magnetic particle testing machine is applicable to the crack detection equipment of bars, pipes, castings, bearings and various kinds of workpieces of ferromagnetic materials. It can conduct circumferential, longitudinal, composite magnetization and demagnetization for workpieces, and the circumferential, longitudinal and composite are all equipped with power-off phase control. The continuous method is used for flaw detection to display magnetic traces in all directions. This machine is controlled by PLC, with all-round magnetism and programmable function. It can automatically realize workpiece rotation → spray magnetic suspension → stop rotation → stop spraying liquid → workpiece clamping → coil moving → section magnetization → observe magnetic trace → demagnetization → manual blanking.
