What are the disadvantages of using a testing machine with an excessive force value to test a sample with a small force value
The electronic universal testing machine uses different tensile forces when testing different products. Why use different tensile forces? Many customers sometimes ask the same type of questions when inquiring about the product. My product only uses 10KG pulling force, but I want a test machine that can achieve 200KG, thinking that it will be bigger in the future. I can still use it when I'm strong. If I buy a testing machine to test the force of the current material, I still have products that exceed this tensile force, then it can’t be used. Why don’t I buy a larger force electronic universal testing machine? Then the problem arises. If the maximum force tested by the testing machine you choose is too large, and now you test a sample with a small force value, the result of the test is not very accurate, which will affect the result of the test, so The force of the product you are testing is not too large, so you don’t need to choose a test machine with too much force. For example: if your pulling force is only 10KG, you want a 200KG tensile testing machine, so the test result is definitely not accurate, because the difference is too far, this does not mean that the test cannot be done, it can be done. , But the result of the test is not accurate. If the customer's requirements are relatively high, they will generally choose a servo tensile testing machine. The test results of this machine are more accurate, because the servo-type testing machine has a relatively high test accuracy. If the customer has no requirements, choose an ordinary electronic universal testing machine That's it. Ordinary tensile testing machines are only for products that are not demanding by customers. If you need high-precision data, it is recommended to buy a computer-controlled testing machine or a servo-type testing machine.
