Effective method to improve the surface roughness of stamping parts

During the stamping process, a certain degree of roughness will be formed on the surface of the stamping part, which is very unfavorable to the normal use of the stamping part. In particular, precision stamping parts not only affect the appearance, but also affect the quality of the product and shorten the service life of the stamping parts. In order to better improve the performance of stamping parts, it is necessary to reduce the surface roughness. Let me take a look at several areas that can be improved: 1. Raw material selection: In stamping processing, many different raw materials are used. According to the different density of raw materials, the selection of tools and machine tools during processing will be directly related to the surface roughness. 2. Cutting amount: In the cutting feed amount, the amount of surface processing can be appropriately reduced. 3. Choose a reasonable processing technology: in the production and processing of stamping parts, the processing technology flow is also very important, and the unreasonable technology flow may affect the processing quality and production efficiency. Many precision stamping parts require rough machining and finishing to complete the finish requirements. 4. Eliminate the influence of accumulated cuts, deal with accumulated cuts quickly, do not cut stamping parts with accumulated cuts on the surface, and at the same time ensure that there are no accumulated cuts on the surface of the tool. 5. Selection of tool geometry parameters: From the machining tool geometry parameters, the secondary deflection angle can be appropriately reduced and the tool tip arc radius can be increased. If necessary, a wiper edge can be ground, which is easier to cut and reduce the surface roughness. 6. Control the vibration of the machine tool: You can start from reducing the friction and extrusion between the tool and the stamping parts, so that the tool blades can be sharpened, adding cutting fluid, and performing appropriate heat treatment on certain tough stamping parts materials. The surface roughness of stamping parts has a very critical influence on the use of stamping products. Therefore, the factors that affect the surface roughness in the processing of stamping parts should be improved or resolved in time to optimize the performance of the processed stamping parts.
