The fatigue testing machine is used to measure the tension, contraction or tension compression of metals, alloy materials and their components (such as operating joints, fixed parts, spiral moving parts, etc.) at room temperature. 2. The fatigue characteristics, fatigue life, prefabricated cracks and crack propagation tests of the negative deviation of the indication under the over differential alternating load. The above two types of products can be divided. 2. When checking the mechanical properties, expand the production to 10000 tons and 5000 tons respectively to find the appropriate text content
