This machine is a special equipment for testing the mechanical properties of arc springs. Equipped with the corresponding fixture, it can also test the mechanical properties of torsional springs , vortex coil spring and elastic components, test the torque value and torsional stiffness of springs at different angles, and measure the Angle under the set torque.
