Method of  Polishing Aluminum:

1. Mechanical Polishing:
The main purpose of this paper is to use polishing wheel coated with polishing wax to process the surface of aluminum alloy shell, which can reduce the roughness of the surface of aluminum alloy shell, make the surface smooth, obtain bright or mirror effect, and effectively repair the scratch and scratch of the surface of aluminum alloy shell.
2. Electropolishing:
Electrolytic polishing is used to immerse the electrolytic bath with chemical reaction as anode and insoluble metal as cathode. The anodized alumina is dissolved by DC, and the alumina disappears from the aluminum profile shell to restore luster.
3. Chemical Polishing:
Chemical polishing can be used as the pretreatment process of protective decorative plating, or as the pretreatment process of chemical film forming such as phosphating hair blue. If the solution of antirust passivation agent is immersed before painting, the aluminum oxide on the surface of the aluminum profile shell can be eliminated.
4. Ultrasonic Polishing:
Ultrasonic polishing is a kind of processing method which uses tool section as ultrasonic vibration and polishing brittle hard material by abrasive suspension. The workpiece is put into the abrasive suspension and put in the ultrasonic field together. Depending on the vibration of ultrasonic, the abrasive can be ground and polished on the surface of the workpiece.
5. Fluid Polishing
Fluid polishing technology needs to rely on the flowing liquid and the abrasive particles carried by it to wash the surface of the workpiece to achieve the purpose of polishing. Hydrodynamic grinding is driven by hydraulic pressure. The medium is mainly made of special compound with good fluidity under low pressure and mixed with abrasive. Silicon carbide powder can be used as abrasive.
6. Magnetic Grinding Polishing
Magnetic grinding polishing is also one of the polishing technologies involved in the processing of aluminum shell. The abrasive brush is formed by magnetic abrasive under the action of magnetic field, and the workpiece is grinded. The method has high efficiency, good quality and easy control of processing conditions. The surface roughness can reach ra0.1 by using the appropriate abrasive μ m.

If there is too deep mark on the surface of the workpiece during polishing, someone will take the pressure to polish and try to throw the trace away. It is unknown that this will hurt the workpiece and cause the dark burn mark on the surface of the part. This phenomenon will be more obvious after chemical polishing, showing the mist like milky white spots, and will remain after anodizing. In order to avoid this phenomenon, in addition to properly reducing the circumference speed of polishing wheel, the polishing process should be prevented by adding polishing paste, reducing the contact pressure between the parts and polishing wheels, and constantly changing the contact parts between the polishing wheel and the parts.

Polished Technology:

The general engineering application of forged aluminum alloy materials or building aluminum profiles is the process of semi-finished products. Aluminum extrusion profile manufacturers usually can directly put profiles into anodizing production line for anodizing. The obtained anodic oxide film has good protection performance in many engineering applications and basically meets the uniform appearance requirements. However, if the mechanical polished aluminum workpiece is anodized directly, only smooth anodic oxide film can be obtained, but not high reflectivity film.
Chemical polishing and electrochemical polishing are advanced finishing methods, which can remove mildews and scratches on the surface of aluminum products; Both of them can also remove the friction band, thermal deformation layer and anodic oxide film which may be formed in mechanical polishing. After chemical or electrochemical polishing, the rough surface of aluminum workpiece is often as smooth and glossy as a mirror, thus improving the decorative effect of aluminum products (such as reflection performance, brightness, etc.). It can also provide higher value-added commercial products to meet the needs of aluminum products with bright surface. Therefore, chemical polishing or electrochemical polishing is needed to achieve smooth, uniform and bright surface.
Chemical polishing and electrochemical polishing can make the surface of aluminum profile very bright, but as far as polishing is concerned, chemical polishing (or electrochemical polishing) is fundamentally different from mechanical polishing
Mechanical polishing is to use physical tools to make the aluminum surface plastic deformation through high-speed cutting and grinding, forcing the convex part of the surface to fill the concave part, so as to reduce the surface roughness of smooth aluminum profile. However, mechanical polishing may damage the metal surface crystallization, and even produce plastic deformation layer and microstructure change layer due to local heating.

Application Case:

Mechanical Polishing:

Electropolishing is commonly used in the decorative processing of steel, aluminum, copper and other parts, or copper nickel and other coatings,

Electropolishing can be used to replace heavy mechanical polishing, especially for its complicated shape and difficult to add by mechanical method

But electropolishing can not remove the non-metallic inclusions in the gold, nor can it remove or mask the metal

Surface defects such as scratches and deep pockmarks on the surface. In multiphase alloys, when one phase is not easy to dissolve in the anode, it will shadow

The quality of electropolishing. Chemical polishing is the chemical etching of metal parts under specific conditions. After this etching

During the process, the metal surface is etched and leveled by solution to obtain a brighter surface

Chemical polishing can be used in the manufacture of instruments, aluminum mirrors, and other parts and coatings

Compared with electropolishing, the advantages of chemical polishing are: no external power supply is needed, and the shape can be processed more easily
