Nowadays, customers who process mechanical parts have relatively high requirements. General precision machining cannot meet their requirements. Custom-made high-precision parts have become their inevitable choice. Under the condition of sufficient assets, such customers will definitely choose to cooperate with the parts processing customization service management center. Although the cost of high-precision parts customization will be much higher, the effect of mechanical parts processing customization is definitely worth the value.
The manufacturer of CNC precision parts processing stated that the rigidity of the parts refers to the ability of the parts to not produce more than the specified elastic deformation when working. This requirement is only for those parts that will reduce the working performance of the machine due to excessive elastic deformation. The principle measures to improve the overall rigidity of the parts include: appropriately increasing the section size of the part, rationally designing the section shape of the part, rationally adding stiffening ribs, adopting a multi-pointing structure, etc.; the principle measures to improve the contact stiffness of the part include: improving the processing accuracy of the contact surface Or after proper running, increase the contact area appropriately to reduce the unit pressure and so on.
The manufacturer of CNC precision parts processing stated that the life requirement of parts is to require parts to maintain normal operation during the expected working period without being scrapped. This requirement is mainly for those parts that are worn or corroded when working under variable stress. Since the main factors affecting the fatigue limit of parts and materials are stress concentration, size, surface quality and environmental conditions, the main measures to improve the life of parts are: ① properly involving the structure of the part to reduce the degree of stress concentration; ② using processing or surface strengthening treatment to Improve the quality of the working surface of the parts; ③ Reasonably select the friction pairing materials, lubricants and lubrication methods to improve the wear resistance of the parts; ④ Choose corrosion-resistant materials to make parts that work in corrosive media; ⑤ Use heat treatment to improve the mechanical parts of the parts materials Performance, or the use of rolling, shot peening and other processes to generate favorable residual stress on the surface of the part.
The manufacturer of CNC precision parts processing said that the process requirements of parts are that under given process conditions and production levels, parts can be manufactured with less cost and labor, and they can be easily assembled. It is necessary to consider all aspects of production batch, material, blank production, processing method, assembly process, use requirements and so on, and design the part structure reasonably. The economic requirements of parts are to use lower cost and less man-hours to manufacture parts that meet the technical requirements. This has a close relationship with the manufacturability of the parts, and affects the economics of the machine to a large extent. It is possible to reduce material consumption, use small or no margin blanks, replace expensive materials with cheap materials, use only high-quality and expensive materials in key parts of the parts, and try to use standard parts as much as possible to improve the economy of the parts.
The above is the basic requirements of parts explained by CNC precision parts processing manufacturers. I hope that after reading it, it will be helpful to you. If you want to know more about CNC precision parts, please contact us, we will wholeheartedly provide you with considerate service!
