What are the hardness requirements for the matching jaws on the testing machine and what are the selection items for purchasing new jaws

Testing machineThe clamping of the specimen is calledTesting machine clampor testing machine fixture. The testing machine clamp is a clamping attachment that assists the testing machine in physical performance testing. It is a consumable part of the material testing machine and is made of special materials processed by special processes. Hardness is one of the important indicators of the clamp. A universal testing machine may be equipped with more than ten types of clamps, such as flat clamps, round clamps, etc. Different specimens require different clamps. Good clamps can improve the accuracy and stability of the test. Poor quality clamps are prone to slip and cannot hold the clamp, which has varying degrees of impact on the testing machine host and test results. Therefore, The hardness of the jaws plays a crucial role in the entire testing machine and subsequent testing processes. Unqualified jaw hardness will shorten the service life of the jaw, and severe non-compliance will result in slippage and prevent the completion of the test.

The clamp of the testing machine is a consumable accessory on the testing machine. When the clamp of the testing machine wears or tears, a new clamp needs to be replaced to ensure the accuracy of the test. But how to choose a matching clamp for the testing machine?

1. Determine the manufacturer, model, year, and tonnage of the testing machine, as the jaws equipped on different models are different;

2. Determine the experiments that need to be conducted, and what experiments should be conducted with what jaws;

3. Choose a reputable manufacturer to provide testing machines with high hardness and good quality, as well as testing machine jaws.
