Classificatio n code
The detailed description is as follows:

1. Perform visual inspection on the workpiece transferred to the polishing process from the previous stage, such as whether the weld has missing welds, welded through, uneven depth of the weld, too far from the seam, partially sunken, uneven butt, and whether there is a deep scratch Marks, bruises, serious deformations and other defects that cannot be remedied in this process should be returned to the previous process for repair if there are any such defects. If there are no such defects, enter the polishing process.
2. For rough grinding, use a 600# abrasive belt to grind the workpiece back and forth on three sides. The goal of this process is to remove the solder joints left by the workpiece welding and the bruises that occurred in the previous process to achieve the fillet of the weld. After preliminary forming, the horizontal and vertical planes basically have no big scratches or bumps. After this step, the surface roughness of the workpiece should be able to reach R0.8mm. Pay attention to the inclination angle of the belt machine and control the pressure of the belt machine on the workpiece during the polishing process. Generally speaking, it is more moderate to be in a straight line with the tossed surface!
3. Semi-finish grinding, use 800# abrasive belt to grind the three sides of the workpiece according to the previous method of grinding the workpiece back and forth, mainly to correct the joints in the previous process and to further finely grind the impressions produced after rough grinding , The marks left by the previous process should be repeatedly ground to achieve no scratches on the surface of the workpiece and basically brighten. The surface roughness of this process should reach R0.4mm. (Be careful not to produce new scratches and bruises in this process, because such defects cannot be repaired in the subsequent process.)
4. For fine grinding, the 1000# abrasive belt is mainly used to correct and grind the small lines that appeared in the previous process. The grinding method is the same as the above. The goal to be achieved in this process is that the seam between the ground part and the unground part of the workpiece basically disappears, and the surface of the workpiece becomes brighter. The workpiece after grinding through this process should be basically close to the mirror effect, and the surface roughness of the workpiece should be able to reach R0. 1mm
5. Instructions for replacing abrasive belts: Generally speaking, 600# abrasive belts can polish 6-8 pieces of 1500mm long workpieces, 800# abrasive belts can polish 4-6 pieces of workpieces, and 1000# abrasive belts can. Polishing 1-2 pieces of the workpiece, the specific situation also needs to be based on the welding spot of the workpiece, the pressure used for polishing, and the method of polishing have a great relationship. In addition, it should be noted that the replacement of the abrasive belt must ensure that the abrasive belt can rotate smoothly on the sponge wheel in order to achieve the purpose of uniform grinding of the workpiece.
Surface effect:
8K: It is also called mirror panel. It is polished on the surface of stainless steel plate with polishing equipment through polishing liquid, so that the luminosity of the surface is as clear as a mirror. Uses: Mainly used in building decoration, elevator decoration, industrial decoration, facility decoration and other stainless steel products.
There are many lines of hairline, including hairline (HL), snowflake sand (NO4), and (chaotic), cross, cross, etc. All kinds of lines are processed by oil-polishing hairline machine according to requirements. become. Uses: Mainly used in building decoration, elevator decoration, industrial decoration, facility decoration and other stainless steel products. The stainless steel champagne gold and pattern board have a strong decorative effect.
A: Oil-milled straight hair/HL: Mainly used for architectural decoration, elevators, building doors, panels, etc.
B: Oil-grinding messy hair: used in elevators, building interior and exterior decoration materials, electrical products, kitchen equipment and food equipment, etc.
C: Dry hair: used in home appliances, elevators, kitchen equipment, decorative materials, etc.

The surface of the galvanized steel sheet presents a unique smooth, flat and gorgeous star flower, and the base color is silver-white. The special coating structure makes it have excellent corrosion resistance. The normal service life of the aluminum-zinc plate can reach 25a, and it has good heat resistance and can be used in a high temperature environment of 315°C; the adhesion of the coating and the paint film is good, and it has good processing properties, and can be punched, cut, welded, etc.; The surface conductivity is very good.
The coating composition is composed of 55% aluminum, 43.4% zinc, and 1.6% silicon in weight ratio. The production process of galvanized steel sheet is similar to that of galvanized steel sheet and aluminized sheet, which is a continuous molten coating process. The galvanized steel sheet with 55% aluminum-zinc alloy coating has better corrosion resistance than galvanized steel sheet of the same thickness when exposed to the same environment on both sides. The aluminum-zinc-plated steel sheet with 55% aluminum-zinc alloy coating not only has good corrosion resistance, but also the color-coated products have excellent adhesion and flexibility.
