After the stainless steel mirror surface is selected, polished, and processed, it enters the final stage of stainless steel processing - polishing.
The polishing process is generally divided into rough polishing → medium polishing → mirror polishing.
Rough polishing: The main purpose of rough polishing is to treat the residual polishing marks in the polishing process. The polishing material is generally treated with a hemp wheel and rough polishing wax. The high pressure and the high temperature generated by the polishing wheel and the steel are used to form a large pressure calendering effect on the stainless steel surface. , Use the ductility of metal to achieve surface flatness and remove grinding marks.
According to the thickness of the grinding marks, the selection of the hemp wheel is generally extra hard ≥ hard ≥ hard ≥ soft ≥ soft.
The corresponding polishing wax selection is: strong cutting black wax (purple wax) ≥ cutting purple wax ≥ large white wax (big blue wax).
In this way of polishing, the treatment of grinding marks is basically satisfied (except for special cases).
Middle throwing: The middle throwing link is progressive from the rough throwing link. The main purpose is to deal with the trace residues of the rough throwing link and further improve the surface flatness and gloss. The following points should be paid attention to in the selection of rough polishing materials:
1. In the process of throwing the wheel, choose a pure cotton polishing cloth wheel with a slightly thicker cloth (paste cotton, canvas, rainproof cloth, denim and other miscellaneous cloths)
2. The selection of matching polishing wax is as follows: large white wax ≥ large green wax ( Medium cast blue wax) ≥ medium cast small white wax. Green wax (higher requirement product)
3. The medium throwing direction and the rough throwing direction are alternately covering directions.
Fine polishing (mirror surface molding): Fine polishing is mainly to carry out the final refinement of the residual traces produced by the intermediate polishing, and finally form a mirror effect.
Material selection pay attention to the following points:
The choice of polishing wheel cloth is more fine, generally pure cotton bleached cloth, this kind of cloth has finer warp and weft yarns and fine soft characteristics, and has an excellent effect on the mirror surface.
The polishing wax selects ultra-polished small white wax (different from medium-polished small white wax) and ultra-polished small green wax (different from medium-polished green wax).
