  Basic Requirements and Surface Properties of Edging Agents in Optical Glass Processing

  Optical glass corrosion and its appearance Optical glass water resistance and resistance to the surrounding environment Acid, alkali and other different media erosion, mainly depends on the optical glass chemical stability, which is different from the composition of the composition of the optical glass and SiO2 content. It is appropriate to add the polishing solution during the polishing process. Too little to participate in the role of the polishing powder particles can be reduced, reducing the polishing efficiency. Too much, some polished particles do not participate in the work, but also bring a lot of liquid to the glass side of the temperature drop, affecting the polishing efficiency. The basic requirements and surface properties of the edging glue in the optical glass processing:

  (1) centering chuck geometric axis and machine tool spindle coincidence accuracy should be more than centering accuracy, generally 0.003 ~ 0.005 mm; this is a lot of use in the infrared optical glass.

  (2) The center of the centering chuck should be strictly perpendicular to the geometry of the chuck; the benefit of the optical glass lens is very good to rely on this point.

  (3) centering the chuck side of the two edges should be geometric axis concentric circles, the formation of thin and equal thickness of the circumference, the surface after grinding and polishing, so as not to scratch the lens;

  (4) The center of the chuck should be 0.2 to 0.5 mm smaller than the diameter of the lens after being centered. After storage for several days or more than 10 days, it is convenient for the parts to be operated and the next machining process. After polishing the plate, and then make a number of additional protective measures, more reliable.

  (5) The direction of inclination of the center of the center chuck is selected according to the surface shape (convex, flat, concave) of the centering chuck. In addition, in order to avoid the centering chuck heating and the lens pressure, chuck to have ventilation holes.
