Stainless steel product tube mirror polishing process
Stainless steel product tube for bathroom, kitchen utensils, furniture and other aspects, the use of large. Some users not only need dimensional accuracy, but also need mirror polishing treatment, especially kitchen appliances, stainless steel tube surface requirements are relatively high, the appearance needs to be bright and clean. The mirror polishing process can not only make the steel pipe not easy to scale, keep bright and clean, but also improve the corrosion resistance. But stainless steel product tube mirror polishing process is how to carry out? It can be divided into the following steps:
One, rough grinding
Double head polishing machine needs to polish the stainless steel pipe 80# or 120# sand belt repeatedly polishing, until the surface of the steel pipe pits flat, the purpose is to initially remove local dents, welding left welding spot, collision and deep scratches.
Two, two coarse grinding.
Rough grinding stainless steel product pipe with 180# sand belt, sand 120# sand belt produced lines. Make the steel pipe free of scratches and collisions. Pay attention to the incline Angle of the belt sander during polishing, and control the pressure of the belt sander on the welded pipe.
Three, half fine grinding
After the second rough grinding, the stainless steel pipe is polished with 240# sand belt, and the lines produced by 180# sand belt are polished away. This process is mainly to correct the joint of the previous process, further fine grinding after two coarse grinding traces, so that the surface without scratches, basic brightening. Be careful not to create new scratches and injuries in the process, as such defects cannot be repaired in the later process.
Four, fine grinding
Sanding semi-polished stainless steel tube with 320# strip and sanding the lines produced by 240# strip. The goal of this process is to make the grinding part and the non-grinding part of the joint basically disappear, the surface further bright.
Five, two fine grinding.
Polish the polished stainless steel welded pipe with 400# belt and polish the lines of 320# belt. The workpiece grinding through this process is basically close to the mirror effect.
Six, half out of light
Repeated polishing of the secondary fine grinding product with hemp wheel 4~5 times, polishing process with polishing wax polishing, can remove 400# sand belt polishing lines.
Seven, out of light
Repeated polishing of semi-luminous stainless steel products with cloth wheel 4~5 times, in the polishing process with stainless steel mirror green wax polishing, can obtain mirror effect, mirror reflectivity up to 6K or 8K.
The above is the mirror polishing process of stainless steel product tube. Through rough grinding, secondary rough grinding, semi-fine grinding, fine grinding, secondary fine grinding, semi-light out, light out seven process steps, with different abrasive belt, hemp wheel and cloth wheel repeatedly polishing, finally obtain the mirror reflectance of 6K or 8K mirror stainless steel product tube.
