    Dynamic and Static Fatigue Testing System

    DTM series electric fatigue testing machine uses an adaptive zero-backlash electric servo actuator, providing fast frequency response, low operating noise, and energy-efficient performance. Compared with hydraulic systems, the electric servo design is especially suitable for small-part testing where clean operation, precise control, and low noise are required.
