How many finish. Electrolytic polishing can reach lowest?
Using the flexible polishing tools and abrasive particles or other polishing medium was carried out on the workpiece surface modification processing. Polishing can improve the size precision of the workpiece or geometric accuracy, but in order to get smooth surface or bright luster for the purpose, sometimes also used to eliminate the gloss (extinction). Usually in polishing wheel for polishing tools. Polishing wheel general use multilayer canvas, felt or leather fold into the system, the two side with a metal powder compact, its rim coated by powder abrasive such as uniform mixture of polishes and grease.
Mechanical polishing is lowest 0.82 mu m, roughness after electrolytic polishing can reach 0.3 microns.
Mechanical processing grinding surface roughness can reach 0.8, electrolytic polishing are not clear
