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.
