Actually, the hardware polishing process can be subdivided into many types. According to its organization status, it is divided into the following categories: ferritic steel, martensitic steel, austenitic steel, austenitic-ferritic stainless steel and accumulation hardening stainless steel Wait. In addition, it can be divided into chromium nickel stainless steel, chromium stainless steel and chromium manganese nitrogen stainless steel according to the composition. At the moment, the appearance of stainless steel has the following types: the appearance of the stone mirror, the treatment of the natural color of the appearance, the treatment of the appearance of the color, etc. The finished stainless steel products in modern life are generally subjected to the process of polishing at the time of production. As long as a few finished products such as the inner tank of the water dispenser and the water heater do not need to be polished. Because the raw material polishing machine can be very good. The main factors that affect the function of the metal polishing plant are the following:

① The appearance of raw materials is shortcoming. Such as scratches, pitting, over pickling, etc.

② Results of raw materials. If the hardness is too low, it will not be easily polished during polishing (the BQ property is not good), and if the hardness is too low, the appearance of orange peel will easily appear during deep drawing, which will affect the BQ property. The BQ with high hardness is relatively good.

③ After the deep drawing process, the area of ​​deformation is extremely large, and small spots and RIDGING will appear on the surface, which will affect the BQ property.

In order to make the stainless steel polishing process externally express the results of mirror light, according to the needs of users and the complexity of stainless steel products, it is possible to distinguish the adoption of chemical polishing, electrochemical polishing, mechanical polishing and other preparations.

Hardware polishing

1. Mechanical polishing:

The mechanical polishing has good leveling and bright light. However, the intensity of the rest is great, the pollution is serious, the complex parts are difficult to process, the gloss falls, and the investment and cost are high. Suitable for simple workpieces, medium and small products, and complex parts that cannot be processed. It is hoped that the gloss of all products in mechanical polishing will not meet the requirements, and the gloss will not be long.

2. Chemical polishing:

Chemical polishing has less investment, complex parts can be thrown away, high efficiency and fast speed. However, the brightness is poor, the polishing liquid needs to be humidified, and there is gas overflow, which requires wind-appropriate equipment. Regarding complex products, chemical polishing is not required for products with low brightness, and small batch processing is more cost-effective.

3. Electrochemical polishing:

Electrochemical polishing achieves mirror gloss, prolonged confrontation, process swing, less pollution, low cost, and good anti-pollution. However, one-time capital investment, complex parts need to be equipped with tooling to assist the electrode, mass production must be cooled. It is suitable for dirty products, long-term confrontation with mirror light and bright products. The electrochemical polishing process is swinging, easy to operate, and can be used throughout the application.
