1. A method for fabricating a super mirror finish stainless steel sheet, comprising the following steps:
1) performing rough machining on a 2B or BA stainless stell sheet, by using a 400-450 grit sandpaper or scouring pad to remove an oxide layer on a surface of the stainless steel sheet;
2) performing finish machining on the stainless steel sheet from step 1), by using a 240-1,000 grit graphite grinding wheel to perform finish grinding;
3) performing polishing processing on the stainless steel sheet from step 2), by using an abrasive material slurry together with polishing wheels, wherein the stainless steel sheet from step 2) is subject to a multi-shaft polishing system, and each polishing shaft drives a polishing wheel, and a cylinder is used to adjust pressure for each polishing shaft in the multi-shaft polishing system, so that all shafts are driven under a same pressure and have equal polishing force
4) obtaining a super mirror finish stainless steel sheet, having a surface finish under 0.01 μm and a reflectivity about 69%.
