How can Manhart (Guangdong) CNC Machine Tool Co., Ltd. effectively eliminate internal stresses in materials after laser cutting?

The effective methods for eliminating internal stresses in materials after laser cutting mainly include the following aspects:
1. * * Heat treatment * *: Heat treatment is a common method of stress relief. By heating the material to an appropriate temperature and holding it for a period of time, followed by slow cooling, the internal stress of the material can be released and redistributed. Annealing and aging treatment are common heat treatment methods.
2. * * Vibration treatment * *: Vibration treatment is a method of relieving stress by applying vibration to a material. The energy generated by vibration can release the internal stress of the material and promote uniform deformation of the material. This method is suitable for materials with high deformation requirements.
3. * * Shot peening * *: Shot peening is the use of high-speed projectiles to impact the surface of a material, introducing compressive stress to counteract the tensile stress inside the material. This method can effectively improve the fatigue resistance and strength of materials.
4. Natural aging: Natural aging refers to the process of placing a material in a natural environment and gradually releasing and reducing its internal stress over time. Although natural aging requires a longer time, it is a feasible choice for materials that do not require high deformation or are not in a hurry to use.
It should be noted that the method of stress relief should be selected based on the specific properties of the material, the magnitude and distribution of stress, and the requirements of the production process. At the same time, materials that have been stress relieved also need to undergo appropriate testing and evaluation to ensure that their performance and quality meet the requirements.
