3、Rough Polishing: with rough polishing abrasive grinding stainless steel surface, the grinding processing method for the criss-cross method: the first longitudinal uniform grinding once, and then uniform horizontal grinding once, to ensure that the grinding direction is always the same, the grinding speed of 1-2M per minute, the spindle speed 40-50r/min. rough polishing mesh in the 600#-1000#. Until the surface treatment is even without pockmarks.

4、Fine Polishing: with wool felt mold with polishing solution on the surface of stainless steel precision polishing, until the surface state achieves no abrasive flower, pockmarks, and scratches, and the surface is uniform and consistent

5、Washing And Drying: use water to wash the chemical liquid on the surface of stainless steel and dry it.

6、Quality Inspection: under the light to achieve no abrasive head flower, orange peel, pitting, scratches. The surface gloss tester test 60 ° ≥ 620, in line with the "export stainless steel decorative plate surface quality inspection procedures" requirements.

7、Filming: filming machine with the processed mirror polished plate for filming, if the plate needs further processing (such as PVD Coating or bead blasted processing), then use white paper or 3C protective film to protect the processed mirror plate, send to the next factory for processing.
