What are the characteristics of Changzhou mechanical processing?

When it comes to Changzhou machining, everyone should be familiar with it. The characteristic of machining is to change the shape of products or materials, which also gives them great advantages when using them. So what are the characteristics of Changzhou machining when changing the shape of materials? Let's listen to the editor of Changzhou Shihui Transmission Parts Co., Ltd. to give us a brief talk!

First of all, it won't change its size, because when users use it, since they change its appearance, it's mostly because of its appearance and size, and if it can't achieve accuracy in size, the product cannot be used.

Secondly, when changing the shape of a material, it has a high dimensional accuracy, which is also an important use requirement. At the same time, when they change the shape, they do not change the nature of the material. More manufacturers often find it meets the requirements in terms of precision and appearance when processing.

The products processed by Changzhou Machinery can also exhibit good processability, because some materials require welding and other processes during processing, and their use in this area also requires high usage requirements.

The process of metal cutting is quite complex, which is not only related to various mechanics, but also affects many different disciplines such as tribology, materials, and mechanical processing technology. During various machining processes, residual stress can form inside the workpiece, which can affect the workpiece, causing deformation or fracture, thereby affecting the processing quality of the workpiece surface, and even affecting the mechanical properties of materials such as corrosion resistance and strength.

With the continuous development of process technology, the requirements for the number of stress cycles and reliability of mechanical processing have also increased. In order to prolong the stress cycle number of a workpiece, it is necessary to improve the machining quality of the workpiece surface, and the physical and mechanical properties of the machined surface layer can have a certain impact on the stress cycle number of the workpiece.

The residual stress formed on the surface during machining can lead to the formation of cracks, and also affect the opening and propagation of cracks. Residual stress can be divided into tensile stress and compressive stress. In general, residual tensile stress can lead to the formation of cracks on the machined surface, which can further expand and affect fatigue strength; On the contrary, residual compressive stress will increase the fatigue life of the workpiece, and by counteracting partial tensile stress, slow down the growth of fatigue cracks.

The influence of residual stress on the number of stress cycles in a workpiece is very complex, which is closely related to the elasticity of the workpiece material, the external stress situation, and the use environment, as well as the strength and distribution of surface residual stress.
