5 ways to improve the surface roughness of stamping parts

Surface roughness is also called smoothness. The surface finish requirements of stamping parts are relatively high, especially precision stamping parts, which are not only beautiful, but also reflect product quality and increase the service life of stamping parts. So in the stamping process, what methods are there to improve the surface roughness of stamping parts? Let's take a look together. 1. Selection of raw materials: In stamping processing, many different raw materials are used. According to the density of raw materials, the selection of cutting 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 machined parts require rough machining and finishing to complete the finish requirements. 4. 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 can be ground to make it easier to cut and reduce the surface roughness. 5. Control the vibration of the machine tool: You can start from reducing the friction and extrusion between the tool and the workpiece, so that the tool is sharpened, adding cutting fluid, and performing appropriate heat treatment on some tough workpiece materials.
