In the process of metal working, the control of internal stress is a key problem. Internal stress is caused by the change of the internal stress state of the material, and too high internal stress may lead to the deformation or cracking of the workpiece, thus affecting its mechanical properties and service life. As a high-precision pressure processing equipment, servo press can effectively reduce internal stress and improve product quality by accurately controlling various parameters in the processing process.

In actual production, a metal processing enterprise uses servo presses to process precision parts. During the processing, they encountered a problem: the internal stress of the workpiece was too high after the completion of the processing, resulting in deformation and even cracking of the part. In order to solve this problem, they began to investigate how to precisely control the internal stress during machining through a servo press.

First, they analyzed the factors that could affect the internal stress during the machining process, such as pressure, speed, temperature, etc. Then, they adjusted these parameters experimentally and observed changes in the internal stress of the workpiece. After many tests, they found that when the pressure and speed are moderate and the temperature is kept constant, the internal stress of the workpiece is lowest.

To achieve precise control of this optimum parameter, they used a servo press. The servo press can monitor various parameters in the machining process in real time, and quickly adjust the pressure, speed and temperature parameters according to the actual demand. By precisely controlling these parameters, the internal stress of the workpiece can be greatly reduced.

After applying the servo press, the company found that the internal stress of the workpiece was significantly reduced, and the deformation and cracking problems of the parts were effectively solved. At the same time, due to the reduction of internal stress, the mechanical properties and service life of the parts are also improved. This not only improves the product quality of the enterprise, but also provides customers with more reliable products.

To sum up, precise control of internal stress during machining by servo presses can improve product quality and reliability. In actual production, it is necessary to analyze the influencing factors of the processing process and find the best combination of parameters. At the same time, the real-time monitoring and rapid adjustment function of the servo press provides a strong support for accurate control of internal stress. In the future, with the continuous progress of technology and the expansion of application fields, servo presses will play an important role in more fields.
