After laser cutting and bending parts, post-processing is a crucial link, which can effectively improve the surface quality of the product and ensure that the final product meets the customer's needs for aesthetics and functionality. The following are some commonly used post-processing methods and their functions:
First, removing cutting residue is the first step in post-processing. During the laser cutting process, some oxides, melts or tiny particles are often left on the surface of the workpiece. These residues not only affect the appearance of the product but may also affect its performance. Therefore, it is necessary to use appropriate tools or chemicals to remove these residues and make the surface clean and smooth.
Secondly, for bent parts that require higher surface quality requirements, grinding or polishing can be used. Grinding can remove uneven parts of the surface and make the bent parts smoother; while polishing can further improve the gloss of the surface and make the product more beautiful in appearance. These processes require the selection of appropriate tools and parameters based on the specific needs and material properties of the product.
In addition, in order to prevent the bent parts from rusting or oxidizing during subsequent use, anti-rust or anti-oxidation treatment can be performed. This usually involves applying a layer of anti-rust paint or antioxidants to form a protective film on the surface of the workpiece, extending the life of the product.
Finally, for some bending parts with special needs, surface coating or spraying can also be carried out. This can not only improve the appearance of the product, but also increase its wear resistance, corrosion resistance and other properties. For example, you can spray a layer of brightly colored paint to make the product more eye-catching, or apply a layer of wear-resistant material to improve its durability during use.
It should be noted that the operation specifications and safety should be ensured during post-processing to avoid secondary damage to the product. At the same time, appropriate post-processing methods should be selected based on the actual needs and material characteristics of the product to achieve the best surface quality improvement effect.
In summary, post-processing after laser cutting and bending parts is a multi-step, multi-method process. Through reasonable selection and operation, the surface quality of the product can be effectively improved and the various needs of customers can be met.
