Polishing refers to the use of polishing wax, hemp wheel, nylon wheel, cloth wheel, wind wheel, wire cloth wheel and other polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece to reduce the surface roughness of the workpiece to obtain bright , A decorative processing method for flat surface. This process can further improve the corrosion resistance and brightening effect of stainless steel.

So, what are the commonly used stainless steel polishing methods for our nameplate company and metal nameplate manufacturers?

Here are our more common seven polishing methods:

1 Mechanical polishing:

Using this technology, the surface roughness of Ra0.008μm can be achieved, which is the highest among various polishing methods.

2 Chemical polishing:

The main advantage of this method is that it does not require complex equipment, can polish workpieces with complex shapes, and can polish many workpieces at the same time, with high efficiency. The obtained surface roughness is generally several 10 μm, which is the most commonly used among the seven kinds of polishing.

3 Electrolytic polishing:

It can eliminate the influence of cathodic reaction, and the effect is better. At the same time, it can increase the corrosion resistance of stainless steel, improve the accuracy of various measuring tools, and beautify metal daily necessities and handicrafts, etc. It is suitable for steel, aluminum, copper, nickel and other products. Alloy polishing.

4 Ultrasonic polishing:

The macroscopic force of ultrasonic processing is small, and it will not cause deformation of the workpiece.

5 Fluid polishing:

abrasive jet machining, liquid jet machining, hydrodynamic grinding, etc.

6. Magnetic grinding and polishing:

This method has high processing efficiency, good quality, easy control of processing conditions and good working conditions. Surface roughness can reach Ra0.1μm.

7. Chemical mechanical polishing:

can achieve surface roughness from nanometer to atomic level. Moreover, the polished mirror effect has high brightness, no fault, and good flatness.

According to its different polishing grades, it can be divided into the following grades of stainless steel polishing pipes:

1. Brightness level

General brightness detectors are divided into 2K, 5K, 8K, 10K, 12 surface effects. The higher the level, the better the surface effect and the higher the price.

According to the visual inspection method, the brightness of the surface of the stainless steel polished tube is divided into 5 grades:

Grade 1: There is a white oxide film on the surface, no brightness;

Level 2: Slightly bright, the outline cannot be seen clearly;

Level 3: Brightness is better, outline can be seen;

Grade 4: The surface is bright, and the outline can be seen clearly (equivalent to the surface quality of electrochemical polishing);

Level 5: Mirror-like brightness.

Stainless steel is also widely used because of its high corrosion resistance and decorative properties, especially in medical appliances, food industry appliances, tableware, kitchen appliances, etc. It has been popularized and promoted.
