Stainless steel polished, shine! What you need to know

Grinding stainless steel?

1. Rough grinding, this process is mainly to remove the solder joints left by the welding on the workpiece and the bumps that appeared in the previous process, to achieve the initial shape of the weld fillet, and the horizontal and vertical surfaces are basically free of large scratches and no scratches. For the purpose of bumping, usually use a 600# abrasive belt to grind the workpiece back and forth on three sides. After this step, the surface roughness of the workpiece should reach R0.8mm. In the polishing process, pay attention to the inclination angle of the belt grinder, and control the pressure of the belt grinder on the stainless steel workpiece. Generally speaking, it is more moderate to be in a straight line with the polished surface!

2. Semi-fine grinding, mainly for repairing the unsealing in the process, and further fine grinding the grinding marks generated in the previous step, and repeatedly grinding the marks left in the rough grinding, so that the surface of the workpiece is scratch-free. marks, surface brightening, etc. Usually, an 800# abrasive belt is used to grind the three sides of the workpiece according to the previous method of grinding the workpiece back and forth. The surface roughness of this process should reach R0.4mm. In this process, no new scratches and bumps should be produced. If this happens, it will be difficult to repair in the subsequent process.

3. Fine grinding, the main purpose of this process is to grind the welding joints of the part and the unground part of the workpiece, remove all scratches and bumps on the surface of the workpiece, and make the surface of the workpiece brighter.

Usually, the 1000# abrasive belt is mainly used to correct and grind the fine lines that appear in the previous process. The grinding method is the same as the above. The workpiece after grinding through this process should be basically close to the mirror effect, and the surface roughness of the workpiece should reach R0.1mm.

Stainless steel products shine?

1. The mirror surface uses a high-speed motor to drive a wool wheel (available in the market), and cooperates with Daqingla to mirror the previous polishing method. The main purpose of this process is to mirror the workpiece that has been polished in the previous steps. light, rather than further grinding. Be careful not to rub the polishing wax on the cover film on the surface of the workpiece during this step, and be careful not to damage the cover film.

2. Polishing This process is the last process of mirror polishing. Use a clean cotton cloth wheel to rub the surface of the workpiece after the mirror surface, and clean and polish the workpiece after all the previous processes are completed. The goal of this process is that the surface of the workpiece cannot be distinguished from welding marks, and the waxed and polished workpiece is polished so that the brightness reaches a specular reflection height of 8k, and the part that has been thrown and the part that has not been thrown is almost indistinguishable. A full mirror effect is achieved.

Surface effect?

8K is also known as mirror panel. The surface of the stainless steel plate is polished by polishing liquid through polishing equipment, so that the brightness of the stainless steel surface is as clear as a mirror.

Main use: Mainly used in building decoration, elevator decoration, industrial decoration, facility decoration and other stainless steel products.

Hairline?

There are many kinds of hair lines, such as hair line (HL), snowflake sand pattern (NO4), and pattern (chaotic pattern), cross pattern, cross pattern, etc. All patterns need to be processed by oil-throwing hairline machine as required made.

Main use: Mainly used in stainless steel series products such as building decoration, elevator decoration, industrial decoration, facility decoration and so on. Stainless steel champagne gold and pattern plate have strong decorative effect.

What are the common types of hair lines?

Oil mill straight hair/HL: Mainly used for architectural decoration, elevators, doors and panels of buildings, etc.

Oil-grinding messy hair: used in elevators, building interior and exterior decoration materials, electrical products, kitchen equipment and food equipment, etc.

Dry hair: used in home appliances, elevators, kitchen equipment, decorative materials, etc.

The use of stainless steel products is becoming more and more frequent, because the appearance of stainless steel products is beautiful. Nowadays, with the development of stainless steel screen printing technology, there are more and more patterns on the surface of stainless steel, which further meets people's needs. The stability and corrosion resistance of stainless steel And strength, etc. also meet the needs of the industry.
