Spring Tester MachineProducts by Easydur
Aura Universal Testing Machine operates with computerized numerical control and includes a computer with HDD and touch screen. It is a self-supporting, two-column structure with ball screws able to reach loads up to 200 Ton. Its electronic setup enables cycles of stress of sinusoidal form resulting in machine preservation and remarkable performance. Aura is the biggest of our Universal Testing Systems and is DC power driven, with encoder (or optical ruler). Aura Universal Testing Machine can be equipped with various kind of extensometers, both contact/mechanical, as well as contactless (video extensometers). Some of the standards for tensile tests: ASTM B557, ASTM E190, ASTM E21, ASTM E290, ASTM E446, ASTM E517.
Main Specifications
Aura Universal Testing Machine operates with computerized numerical control and includes a computer with HDD and touch screen. In this configuration, Aura can be defined as a dynamometer, with a self-supporting, two-pillar structure equipped with ball screws. The electronic setup of this spring tester enables cycles of stress of sinusoidal form resulting in machine preservation and remarkable performance (loads up to 200 Ton, so it’s a heavy weight dynamometer. DC power driven, encoder (or optical ruler).
The term “Chasse” designates a spring testing machine capable of detecting axial, transversal and lateral stiffness, deflection and bowing angle according to Railway standards. Aura Chasse employs a fully-motorized platform and is available in models with capacities ranging from 5 to 60 Ton.
Electromechanical machine able to perform loads from 5 to 60 tons for compression tests on railway springs with a 0,5% – class precision or better. Equipped with a full motorized platform aimed to detect axial, transversal and lateral stiffness, deflection and bowing angle according to Railway standards, such as: EN 13298, EN 13913 (conical springs).

The Arco model leaf spring testing machine is the ideal solution for performing compression and bending tests on leaf springs mainly intended for railway and automotive applications.
Depending on the type of leaf spring suspension, and in particular depending on the compression forces involved, Easydur is able to design and build an ergonomic solution to suit every application requirement.
The load cell of the leaf spring testing machine is placed on the central plate moved along the vertical axis. Thanks to this design, it is possible to test several products such as leaf springs, coil springs and general spring components using the same machine.
The two ends of the mother leaf of the leaf spring are secured with special locking pins positioned on a movable carriage, to ensure stable locking and, with the addition of optional sensors, to measure the extension of the leaf spring as a result of the applied compression force.
Dynamics is a machine for dynamic and fatigue tests on springs, as well as for tests on materials, available in various versions, based on different technologies (electromechanical and hydraulic cylinder). Totally customizable, it can best adapt to every need in terms of load, stroke, speed and frequency.
After measurement, the springs are divided into 5 classes thanks to a spray-marking system with 5 colours depending on the set tolerances, so as to avoid a sorting system with several channels. In this model, two spring testers work simultaneously to save time. The first spring tester settles the springs with a programmable number of pressing operations, while the second performs the test cycle of a classic spring tester. The springs are conveyed by hydraulic grippers and it is really simple to change the family of springs to be tested. To perform a test, the user need only enter the few necessary parameters and press the GO button. A complete test cycle lasts only 15-19”.
The three load cells are fitted at 120°, with reading at 1,000 Hz and 200,000 divisions. The cells are protected against overload and with the release of the automatic axis in the event of out of scale values or of unforeseen impact and they have integrated compensation of cell sagging.
The system is controlled by a PLC and by a computer with touch screen and software entirely developed by Easydur and based on Windows with internal management of archives, statistics and certificates in Excel format, totally modular and customisable by the customer.
