The following is a detailed analysis of the eight processes of optical cold processing
The first is to remove the lens: milling, uneven surface bubbles and impurities (about 0.05-0.08) plays the role of forming.
Second: the fine grinding process is to mill out of the lens will be the destruction of the layer to eliminate the fixed R value.
Third: the polishing process, the polishing lens is once again polishing, this process is mainly to make the appearance of better.
Fourth: cleaning, the lens will be polished after polishing the surface of the powder to clean.
Fifth: grinding edge, the original lens outside diameter will be grinding to the specified outside diameter.
Sixth: coating, there is a need to film the surface of the lens coating on one or more layers of colored film or other film
Seventh: the ink is, there will be a need to prevent reflective lens on the outer layer, Tushang black ink.
Eighth: balsaming, there will be 2 R lens size and diameter instead of adhesive material as their joint. Special process: multi chip processing (disk processing) and small machining (20 with axis) line cut according to different production processes, the process will be slightly different, such as ink and coating the bond order.
