Understanding the standard of test accuracy of spring material torsion test machine

Jinan Hengsi Shanda Instrument Co., Ltd. springMaterial torsion test machineThe test accuracy standards are introduced in detail so that customers can understand:

The primary requirement for high-stiff precision springs is the equipment with high test accuracy and low load springs. Because the slight changes in displacement will cause a large change in the test force, and it is easy to ensure the test accuracy of the test force. However, it is important to ensure the accuracy of the displacement of another parameter of the spring test machine, ensuring the spring test accuracy, and it is also a standard for judging the accuracy of the spring test machine. Therefore, more and more users regard the accuracy of displacement testing as a standard for measuring the level of the test machine. springMaterial torsion test machineIn the national specifications, the displacement accuracy requirements are very low and cannot meet the requirements of high-stiff precision springs. Therefore, for test machine manufacturers, it is necessary to improve the displacement test accuracy to meet the user's requirements. There are many factors that affect the accuracy of displacement testing, such as detection methods, machine structure, machine stiffness, pressure plate parallelism, measurement components, data, load displacement sinking, etc. As long as these factors are overcome, the guarantee of displacement accuracy is not a problem.
