Embodiment 1
[0048] like figure 1 As shown in the schematic diagram of the polishing process of the spherical lens, for the biconvex spherical lens 6, the upper and lower grinding tools 4 and 5 of the biconvex spherical lens are used for double-sided polishing. Place the biconvex spherical lens 6 directly in the middle of the upper and lower abrasives 4 and 5 of the biconvex spherical lens, and adjust the position to ensure that the upper and lower surfaces of the biconvex spherical lens 6 and the inner surfaces of the upper and lower abrasives 4 and 5 of the biconvex spherical lens Then, through the rotation of the upper and lower grinding tools 4 and 5 of the biconvex spherical lens, the surface material of the lens is continuously removed to achieve the double-sided polishing of the biconvex spherical lens 6 .
[0049] like figure 2 , 3 As shown, when the upper and lower grinding tools are cambered disc grinding tools 7 or spherical grinding head grinding tools 10, the biconvex spher...
Embodiment 2
[0059] like Figure 4 As shown, for the concave-convex spherical lens 14, the upper and lower abrasive tools 12 and 13 of the concave-convex spherical lens are used for polishing, and the polishing process is similar to that in Embodiment 1; The meniscus spherical lens 14 is polished. When using the plane disc abrasive tool 18 and the spherical abrasive tool 10, the concave-convex spherical lens 14 needs to be concentrically installed in the circular retaining ring 8, and the retaining ring 8 and the inner ring of the bearing 9 have an interference fit. The ring 8 and the concave-convex spherical lens 14 are rotatable relative to the inner ring of the bearing 9 . Adjust the position to ensure that the upper and lower surfaces of the concave-convex spherical lens 14 are in point contact with the surfaces of the plane disc grinder 18 and the spherical grinder 10, and then through the rotation of the upper and lower grinders 12 and 13 of the concave-convex spherical lens, the le...
Embodiment 3
[0068] like Figure 5 As shown, for the double concave spherical lens 17, the upper and lower grinding tools 15 and 16 of the double concave spherical lens 18 can be used for polishing, and the polishing process is similar to that of Embodiment 1; Figure 8 As shown, for the double concave spherical lens 17, the double concave aspheric lens 20 can also be polished by the combination of the upper and lower spherical grinding head grinding tools 10. When using the upper and lower spherical grinding head abrasive tool 10, the double concave aspheric lens 20 needs to be installed concentrically in the circular retaining ring 8, and the retaining ring 8 and the inner ring of the bearing 9 have an interference fit. The concave aspheric lens 20 is rotatable relative to the inner ring of the bearing 9 . Adjust the position to ensure that the upper and lower surfaces of the double concave aspheric lens 20 are in point contact with the surfaces of the upper and lower spherical grinding...
