About what the owner asked, the testing machine Lao Er that the operation of the universal testing machine procedures are as follows:
1. Equipment inspection: before use, the universal testing machine must be inspected, including the various systems of the equipment (such as the control system, the heating system, the hydraulic system, etc.) to ensure that the universal testing machine for normal operation. At the same time check the environment around the equipment to ensure safety and ensure that the use of equipment will not cause danger to others.
2. Equipment calibration: Before performing any mechanical test, the equipment must be calibrated according to the required measurement parameters. Therefore, calibration should be done according to the characteristics of the material being tested to ensure the accuracy of the test results.
3. Preheating: To ensure that the equipment is in good condition before sample testing, the sample and equipment should be preheated. This helps to improve the accuracy of the test results. The warm-up time depends on the specific test material and equipment functional requirements.
4. Sample Fastening: Snap or secure the sample or specimen tightly in place, which is very important before performing tests such as tensile or compression tests. The operator should ensure that the determined tightening force does not alter the test results, e.g. by using manual or automatic clamps or circlips, or by protecting the sample with rubber pads, etc.
5.
5. Test modes: When performing mechanical tests, the appropriate test mode must be selected. Usually there are tensile, compression, bending, tension shear and shear tests. Detailed understanding of the test sequence, sample tightness and readings, etc..
6. Data Processing: After performing the mechanical test, the resulting data must be processed so that the data is interpreted into very important test conclusions. For this purpose, the operator should be familiar with the data analysis software. In addition, before conducting the test, make sure that the equipment is reading and formatting the data correctly.
