304 stainless steel tube grinding and polishing method has many kinds, at present with relatively more mechanical polishing and electrolytic polishing and polishing, two different types of polishing and polishing methods are not the same difference, in the price cost is also a certain difference.

304 stainless steel pipe polishing method

First of all to understand what is polishing. Polishing refers to the use of mechanical, chemical or electrochemical effects, reduce the surface roughness of the workpiece, make its surface bright and smooth processing methods. It is the process of finishing the surface of the workpiece using a stainless steel pipe polishing machine and abrasive particles or other polishing media. Polishing cannot improve the dimensional or geometric accuracy of the workpiece, but to obtain a smooth surface or mirror luster.

Stainless steel tube polishing is also a variety of ways, the current use of more mechanical polishing and electrolytic polishing. There are some differences between the different polishing methods, there are also some differences in cost.

1, mechanical polishing

Mechanical polishing treatment is mainly for internal surface grinding and polishing, put the throwing rod into the 304 stainless steel tube, drive the inside of the millipede wheel can be economic high-speed rotation. In the process of continuous rotation, stainless steel tube inside the surface layer is not smooth can be polished. General mechanical polishing is also divided into rough polishing and fine polishing, there are some higher requirements of the product requirements can be fine polishing. In the fine polishing needs to be 304 stainless steel tube coated with the appropriate amount of polishing paste, increase the sense of brightness of the surface, the price cost of this polishing method will be relatively high.

Mechanical polishing can make 304 stainless steel tube has good flatness and brightness, but the labor intensity required is large, pollution is serious, complex parts can not be processed, investment and cost is high, gloss adherence time is not long, easy to smother, rust.

2、Electrolytic polishing

Electrolytic polishing method is more labor-saving compared to the mechanical polishing method. But we need electrolytic tools and equipment, we have to be polished 304 stainless steel tube as the anode, insoluble metal side as the cathode, and then the two electrodes at the same time into the electrolytic tank, and then on the current, electrolytic polishing, until we want to achieve the effect of the surface bright. The cost of this polishing method will be relatively more expensive, but the polishing effect is better than the mechanical polishing method. After polishing, the surface layer of stainless steel tube oxidation layer will be destroyed, therefore, the surface layer needs to be passivated with an acidic solution to maintain the anticorrosive properties of the surface layer, otherwise it will cause the surface layer of stainless steel tube to rust easily, but the loss is not worth it.

The above content is 304 stainless steel pipe polishing commonly used two methods, polished stainless steel pipe not only improves the aesthetics of the stainless steel pipe, but also improves the corrosion resistance of stainless steel pipe, polished stainless steel pipe products have a long service life, and a wide range of uses.
