304 STAINLESS STEEL STRIP COIL POLISHED SURFACE

Stainless steel strip coil 304 grade polished surface can be divided into the following seven types: mechanical polishing, chemical polishing, electrolytic polishing, ultrasonic polishing, fluid polishing, magnetic grinding polishing, chemical mechanical polishing.
1. Mechanical polishing: Mechanical polishing is by cutting, material surface plastic deformation to remove the convex after polishing and smooth surface polishing method.
2. Chemical polishing: Chemical polishing is to make the material in the chemical medium surface of the micro convex part of the dissolution of the concave part, so as to get a smooth surface. The main advantage of this method is that it does not need complex equipment, can polish the workpiece with complex shape, can polish many workpiece at the same time, high efficiency.
3. Electrolytic polishing: The basic principle of electrolytic polishing is the same as that of chemical polishing, that is, it makes the surface smooth by selectively dissolving small protruding parts on the surface of the material. Compared with chemical polishing, the effect of cathode reaction can be eliminated and the effect is better.
4. Ultrasonic polishing: It is to put stainless steel strip coils into the abrasive suspension and placed in the ultrasonic field.
5. Fluid polishing: It relies on the high speed flowing liquid and the abrasive particles it carries to wash the stainless steel strip coil surface.
6. Magnetic grinding and polishing: It is using magnetic abrasives under the action of magnetic field to produce stainless steel strip coils of abrasive brush, grinding surface.
7. Chemical mechanical polishing: Chemical-mechanical lapping technology combines the advantages of chemical and mechanical polishing.

Polishes Stainless Steel Strip Coil Advantages:

1. Mechanical polishing.
Its advantage is that the leveling of the processed parts is good and the brightness is high. Its disadvantage is that the labor intensity is high, the pollution is serious, and complex parts cannot be processed, and its luster cannot be matched, the luster does not last long, and it becomes stuffy and rusty. More suitable for processing simple parts, medium and small commodities.
2. Chemical polishing.
Its advantages are less investment in processing equipment, complex parts can be thrown away, fast speed, high efficiency, and good corrosion resistance. Its disadvantages are poor brightness, gas overflow, ventilation is required, and heating is difficult. It is suitable for processing small batches of messy parts and products that do not require high brightness of small parts.
3. Electrochemical polishing
Its advantages are long-lasting specular gloss, stable process, less pollution, low cost and good corrosion resistance. Its disadvantages are high pollution resistance, large one-time investment in processing equipment, tooling and auxiliary electrodes for complex parts, and cooling equipment for mass production. Suitable for mass production, mainly used in high-end products, export products, public service products, its processing technology is stable, and the operation is simple.
