How can the die polishing be mirror?
Chemical polishing chemical polishing allows the surface of materials, chemical media, micro protruding part of the concave part of the priority dissolved, so as to obtain smooth surface. The main advantage of this method is that it does not require complicated equipment. It can polish workpieces with complex shapes, and can also Polish many workpieces at the same time, and the efficiency is high. Keywords chemical polishing; core problem; polishing fluid; preparation. The surface roughness obtained by chemical polishing is generally 10 mu m.
Mechanical polishing, mechanical polishing by cutting material surface plastic deformation was removed after polishing and smoothing convex surface polishing method, the general use of oilstone, wool wheel, sand paper, mainly manual, special parts such as rotary table surface, can use auxiliary tools such as high surface quality requirements by ultra precision polishing methods. The lapping machine adopts special grinding tools, which contain abrasive polishing liquid, and the workpiece is pressed on the machined surface for high speed rotary movement. With this technique, the surface roughness of Ra0.008 and M can be achieved, and the polishing methods are the highest. Optical lens molds are often used in this way.
