Product Description

The spring fatigue testing machine is mainly used for the tension and compression fatigue life test of all kinds of tension springs, compression springs, elastic bodies and elastic components. Through computer control, the test can be started by setting the amplitude, test speed and number of tests. The force value and the number of tests are displayed in real time. When the set number of tests is reached or the force value is attenuated, it can automatically stop. The machine has high integration, simple operation, low failure rate, stable and reliable performance, and is widely used in spring manufacturers, factories and mines, scientific research institutions, quality inspection units and other industries.

Routine Maintenance Of Spring fatigue testing machine
Routine maintenance
1. In order to protect personal safety, the spring fatigue testing machine should be properly grounded.
2. After use, cover the machine to prevent dust from falling into the machine.
3. Lubricating oil should be often added to the lifting rack and each pressure-injection oil cup.
4. Under normal conditions of use, the validity period for one-time verification of the indication error is one year.
5. During operation, especially when unloading, do not let go of the hand, so as to avoid violent vibration and affect the accuracy of the testing machine.
