Stainless steel mechanical polishing

Note: We should keep in mind that grinding with abrasive paper or abrasive belts is basically a burnishing operation, leaving very fine lines on the steel surface. We have had trouble with alumina as an abrasive, due in part to pressure problems. Any abrasive parts of the equipment, such as belts and grinding wheels, must never be used for other non-stainless steel materials before use. Because it will pollute the stainless steel surface.
