Photometric analysis of GB elbow

Gb elbow after the production of the word generally to polishing processing, through polishing let our GB elbow light. A few words about polishing:

Gb elbow through the introduction of machine polishing: mechanical polishing is divided into rough polishing and fine polishing. Rough polishing is done with duffle on a 200-300 RPM electric throwing disc. In the process of rough polishing, it is appropriate to sprinkle rougher chromium oxide, alumina or magnesium oxide polishing liquid, and adhere to the wetting of the wool on the disc. In the rough polishing process to hold the sample, along the radial reciprocating motion of the disc, evenly adjust the pressure applied, pay attention to the pressure should not be too large. At the beginning of polishing, sprinkle some polishing liquid from time to time. Gradually reduce the pressure and the concentration of the polishing fluid until the polishing is smooth and smooth with no black spots. The rough-polished sample is washed and then finely polished. The abrasive marks left by rough-polished sample are removed through fine polishing to make the grinding surface bright and flat. The machine used for fine polishing is essentially the same as that used for rough polishing, with a speed of 150-200 RPM.

Gb elbow chemical polishing: chemical polishing is to make the data in the chemical medium surface of the micro protruding part of the concave part of the priority to dissolve, and then smooth the surface. The main advantage of this method is that it does not need complex equipment, can polish the workpiece with complex shape, and can polish many workpiece at the same time. The core problem of chemical polishing is the manufacture of polishing fluid. The surface roughness of chemical polishing is generally 10μm.

Bangle point depolishing: the metal ions detached from the workpiece and the phosphoric acid in the polishing liquid form a layer of phosphate film adsorbing on the surface of the workpiece. This kind of mucosa is thinner at the bulge and thicker at the concave part. Due to the high current density at the bulge, it dissolves quickly.
