The control methods of the surface finish of sheet metal parts mainly include the following aspects:
Precision and maintenance of processing equipment: High-precision processing equipment is the basis. For example, the laser cutting machine needs to calibrate the optical path system regularly, and the blade and gap of the shearing machine need to be reasonably adjusted and replaced regularly. These measures can ensure the accuracy of the cutting and shearing process and avoid burrs and unevenness on the surface.
Reasonable selection and control of processing technology:
Cutting process: Laser cutting can provide a smoother cutting surface than flame cutting because the energy density of the laser beam is high, the incision is narrow, and the heat-affected zone is small.
Bending process: Accurately control the pressure and speed of bending to avoid indentations on the sheet metal surface. It is also important to use a suitable bending mold. The surface quality of the mold and the fit with the sheet metal will affect the surface flatness after bending.
Surface treatment: Grinding and polishing are key steps to improve the surface finish. Use sandpaper of different meshes to polish step by step to remove surface defects and oxide layers, and then use polishing wheels and polishing paste to further improve the surface finish.
Quality control of raw materials: Choose plates with qualified quality to avoid problems such as uneven surface, delamination or impurities. For high-demand products, cold-rolled plates can be selected, whose surface accuracy and finish are usually higher than hot-rolled plates.
Operating environment and personnel quality: A clean and tidy operating environment can reduce the contamination of impurities on the sheet metal surface. The skills and sense of responsibility of the operator are also very important. Skilled operators can better master the equipment parameters and process skills to avoid damage to the sheet metal surface due to improper operation.
Of course, through the above measures, the surface finish of the sheet metal parts can be effectively controlled to ensure the quality of the product and the appearance of the product. In fact, the sheet metal service provider has taken all of this into consideration. If your sheet metal supplier is professional and reliable, then the sheet metal processing you entrust will be easy, because all the process problems will not worry you.
