  • Do you have any idea about the principle of stainless steel surface polishing?
    Nov 06, 2018

    Stainless steel polishing is a process that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of the workpiece in order to obtain a bright and smooth surface. 

    Using flexible polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece, polishing can not improve the dimensional accuracy or geometric accuracy of the workpiece, but for the purpose of obtaining smooth surface or mirror gloss, and sometimes for eliminating gloss (extinction). 

    Polishing wheel is usually used as polishing tool. The polishing wheel is usually made of multi-layer canvas, felt or leather. The two sides are polished with metal circular plates. The flange of the polishing wheel is coated with polishing agent which is uniformly mixed with micro-abrasive and grease.

    When polishing, the high-speed rotating polishing wheel (the circumferential speed is over 20 meters/second) is pressed onto the workpiece. By rolling and micro-cutting the abrasive on the workpiece surface, a bright surface can be obtained. The surface roughness can generally reach Ra 0.63-0.01 micron. When non-greasy polishing agent is used, the bright surface can be extincted to improve the appearance.
