    5. Why are there white strips on the surface of the workpiece after the electropolishing process? Analysis of causes: Relative density of the solution is too high and the liquid is too thick. The relative density is greater than 1.82. Solutions: Stir the solution more. If the relative density of the solution is too high,...

    6. Brushed Metal Brushed metal is a kind of surface treatment that grinds surfaces of workpieces and forms patterns of very fine lines on workpieces’ surfaces, and brushed metal can make metal parts have decorative effects. Brushed metal can be classified into straight line brushed metal, disorderly line brushed...
