They are used for tension-compression, torsion, fatigue, sorting and strength test of various kinds of springs, I.e. helix spring, worm spring, papilionaceous spring etc.
This kind of machine adopts the theory of electromagnetic excitation and specimen (spring) resonance. The system is in the best resonance condition automatically without adjustment. It may be trigged at any moment and the performance is stable and reliable. The tester can display vibration times ,frequency and pre-set times.
