Several abrasive polishing method

1, the mechanical polishing: mechanical polishing is by plastic deformation of the cutting surface of the material to be removed after polishing to obtain a smooth surface protrusions polishing method is Sanding Sheets  generally used Whetstone bar, wool wheel, sandpaper, belt, nylon wheel, so as to manual operation of Lord, special parts such as rotary body surface, you can use the turntable and other auxiliary tools, high surface quality requirements can be thrown over lapping method. Superfinishing throw is to use a special abrasive abrasive, abrasive polishing containing liquid, pressed on the surface of the workpiece to be machined for high-speed rotation. A variety of polishing method in the highest. Optical lens mold often use sandpaper roll  this method.2, chemical polishing: chemical polishing is to make the surface material in the chemical medium microscopic concave portion projecting some of the more preferential dissolution, resulting in a smooth surface. The main advantages of this approach does not require complicated apparatus, the complex shape of the workpiece can be polished, can be velcro disc  polished simultaneously many parts, and high efficiency. The core problem is that the chemical polishing slurry preparation.
3, electrolytic polishing: electrolytic polishing and chemical polishing the same basic principles, i.e. the material surface by selective dissolution of small projecting portion, the surface smooth. Compared with chemical polishing, can eliminate the impact of the cathodic reaction is better. Electrochemical polishing process of leveling the macro and micro-leveling.
