COIL SPRING TESTING MACHINES with nominal load from 5 to 500 KN are characterized by a vertical servo-controlled actuator which charges the spring and detects the deflection and the force exerted by means of a potentiometer and load cells.
To detect the chasse is provided a floating table which is equipped with two potentiometers allowing to detect the motion of the spring base in relation to its axis during compression. These machines can be also equipped with a lateral actuator that, by means of the floating table, detects the spring lateral flexibility.
Through data acquired is possible to perform files in Windows environment with diagrams characterizing the spring.
