The processing technology of mirror polish stainless steel sheet is relatively complicated, mainly including the following steps:
1. Mechanical grinding
Rough grinding: First, use coarse-grained abrasives to preliminarily grind the surface of the stainless steel sheet to remove obvious defects, scratches and oxide layers on the surface. This process usually uses tools such as sanding belt machines or grinding wheels to remove a large amount of material at a faster speed, laying the foundation for subsequent fine processing.
Medium grinding: Then use medium-grained abrasives for further grinding to make the surface smoother. This step can reduce the wear marks left by coarse grinding and improve the flatness of the surface.
Fine grinding: Use fine-grained abrasives for fine grinding to make the surface of the stainless steel sheet reach a certain degree of finish. At this stage, the grinding pressure and speed need to be controlled to avoid new scratches.
2 Chemical polishing
Chemical polishing is to remove the microscopic unevenness of the surface of the stainless steel sheet through chemical reactions to make it smoother. The stainless steel plate is immersed in a specific chemical solution, and the chemicals in the solution react with the stainless steel surface to dissolve the tiny protrusions, thereby achieving the polishing effect. The advantages of chemical polishing are fast processing speed and the ability to process workpieces with complex shapes, but the composition of the solution and operating conditions need to be strictly controlled to ensure the quality of polishing.
3. Electrolytic polishing
Electrolytic polishing is the use of electrochemical principles to polish stainless steel sheets. The stainless steel sheet is used as an anode, placed in an electrolytic cell, and direct current is passed through a specific electrolyte. Under the action of the electric field, the metal ions on the surface of the stainless steel are dissolved, making the surface smoother. Electrolytic polishing can achieve a very high degree of finish, and can remove impurities and microscopic defects on the surface, improving the corrosion resistance of the stainless steel plate.
4. Cleaning and inspection
After polishing, the stainless steel plate needs to be thoroughly cleaned to remove impurities such as chemicals and abrasives remaining on the surface. Then a strict inspection is carried out to check the surface finish, flatness, and defects. If it does not meet the requirements, further processing or repair may be required.
In short, the processing technology of mirror polish stainless steel sheets requires the comprehensive use of multiple methods such as mechanical grinding, chemical polishing, and electrolytic polishing. After strict operation and inspection, a high-quality mirror effect can be obtained.
