Stainless Steel Sheet Metal Processing In the polishing process, there are a variety of techniques that can be employed to ensure that the polishing effect is good. The following are some of the main polishing techniques, which are summarized as follows: 1. Select the appropriate polishing tool < unk > Selection of polishing wheel: Pre-polishing: Use a hard or harder polishing wheel to carry out preliminary treatment on the surface of stainless steel sheet metal to remove rough marks on the surface. Fine polishing: Use a soft polishing wheel to further process the surface after pre-polishing to remove the marks left by pre-polishing and obtain the effect of a bright mirror surface. < unk > Other auxiliary tools: such as wool wheels, cloth wheels, etc., used in combination with polishing paste, a more delicate surface effect can be obtained. II. Control polishing parameters < unk > Speed control: Stainless steel polishing should be carried out at a low speed to avoid surface damage caused by excessive polishing temperature. < unk > Pressure adjustment: When polishing, the polishing pressure should be adjusted appropriately according to the material, hardness and other factors of the polishing wheel and workpiece to obtain a uniform polishing effect. III. Preparation before polishing < unk > Cleaning: Before polishing, the surface of the stainless steel sheet metal should be thoroughly cleaned to remove oil, dust and other impurities on the surface to ensure that the polishing wheel can directly contact the surface of the workpiece. < unk > Surface treatment: For stainless steel sheet metal parts with defects such as burrs and flying edges on the surface, chamfering, deburring and other treatments should be carried out first to avoid damaging the polishing wheel or affecting the polishing effect during the polishing process. IV. Precautions in the polishing process < unk > Polishing wheel cleaning: When using a polishing machine, it should be ensured that the polishing wheel is clean and free of impurities to avoid contaminating the surface. < unk > Temperature control: During the polishing process, attention should be paid to controlling the temperature to avoid oxidation or deformation of the surface of the workpiece due to excessive temperature. < unk > Uniform polishing: A uniform polishing speed and pressure should be maintained during polishing to avoid uneven surface phenomena. V. Treatment after polishing < unk > Cleaning and drying: After polishing, the surface should be rinsed with water immediately to remove the residual polishing paste and abrasive. Then the workpiece is dried using a vibrating dryer or other methods. < unk > Passivation treatment: In order to improve the anti-corrosion and anti-rust performance of the workpiece, it can be soaked in a stainless steel passivation solution after polishing to restore or enhance the passivation film on Six, special polishing skills < unk > Magnetic polishing: For some workpieces with complex shapes or difficult to handle by traditional polishing methods, magnetic polishing technology can be used. This technology uses magnetic force to adsorb the polishing abrasive on the surface of the workpiece for polishing, which has the advantages of high efficiency and uniformity. < unk > Electrolytic polishing: Electrolytic polishing is a method of polishing using electrochemical principles. By controlling the composition of the electrolyte and electrolytic conditions, a dense protective film can be formed on the surface of the workpiece, and a smooth and bright polishing effect can be achieved. However, this method is complicated and costly, and is suitable for occasions where high precision is required.
