Normaly there are two ways to make steel products with miror surtace.0ne way is Chemical reacent steeping and the other one is viastainless steel automatic polishing machine which is more environmentally friendly than chemical way.

chemical reagent way polishing is a method of eliminating the wear scar and eroding the flatness by the chemical agent's selective dissolution of the stainless steel surface.The biggest disadvantage is polluting environment,so more and more workshops choose automatic polishing machine to make steel surface grinding buffing

The principle of stainless steel polishing machinethe grinding wheel is rotated by the motorand friction is generated with the rotatingworkpiece on the grinding rotary table, and the cuting force is generated by friction to smooth the uneven surface of the workpiece to achieve the purpose of polishing.

Both abrasive sanding belts and buffing wheels are available on automatic polishing machine,grit mash from 80# to 1200# and it wil be easy to get mirror finishing via polishing machine step by step.

You could get surace roughness Ra≤0 25um after buffing via polishing machine.via it's hard to reach it via chemical way Stainless steel mirror polishing generaly uses a polishing machine to polish the polishing machine can remove scratches spots sag on stainess steel workpiece surface so that the surface of the workpiece is bright smooth and mirror-like.

Should any requirements on steel metal surface treatment welcome contact us directly,There is at least one auto grinding solution will meet your demands.
