(Summary description)The first: milling, is to remove the surface of the lens uneven bubbles and impurities,(about 0.05-0.08) play a molding role.

The second is the fine grinding process, is to mill out the lens to eliminate its damage layer, fixed R value.

The third step is the polishing process, which is to polish the finely ground lens in one time. This process is mainly to make the appearance better.

The fourth way is cleaning, is to polish the lens after the surface of the polishing powder clean. To prevent that press a gram

The fifth way is edge grinding, also known as coring, is to grind the original lens diameter to the specified outer diameter.

The sixth is the coating, is the need to coating the lens surface with a layer or multiple layers of colored film or other film

The seventh way is to paint ink, is to need the lens to prevent reflection on its outer yuan coated with a layer of black ink.

The eighth way is glue, is to have 2 R value opposite size and outer diameter of the same material lens with glue.

Special processes: multi-piece machining (plate machining) and small spherical machining (20 with shaft) line cutting according to different production workers

Art, the process will be slightly different, such as the order of ink and glue
