Problems solved by technology

The manufacture of rubber cups generally adopts the method of mold pressing, and one kind of specification needs to manufacture a kind of mold. In actual production, the manufacturing cost of the mold is very high. If the method of convex surface cup is adopted, the production cost and cost will be greatly increased. cycle
[0003] On the other hand, the existing single large-diameter polished large-scale high-deep concave spherical surface still faces the problem of surface shape control
At present, large disc polishing is used for spherical CNC polishing.

Abstract

The invention discloses a polishing method for a high-rise deep-concave spherical lens. When a high-rise deep-concave spherical surface is polished, an elastic rubber cup is used for supporting the lens; and when the surface of the sphere is polished, a protective layer and a filling layer are manufactured on the polished high-rise deep-concave spherical surface, and the lens is supported through the filling layer. The method is simple, reasonable and convenient to implement; by adding the filling layer, the high-rise deep-concave spherical lens can be effectively supported in the polishing process, support with even stress can be achieved without independently customizing a special supporting cup, and the manufacturing cost is greatly reduced. Meanwhile, in the machining process, machining of two faces can be achieved only by one supporting tool, so that the machining procedure is simplified, the machining efficiency is improved, and the polishing method for the high-rise deep-concave spherical lens is rapid and low in cost.

Description

technical field [0001] The invention belongs to the field of optical processing, and relates to a polishing method for a large-scale high-deep concave spherical lens. Background technique [0002] With the development of optical processing technology, spherical lens CNC polishing technology has been widely used. In the process of CNC polishing of spherical lenses, there are generally two ways to support the spherical lens, one is the floating support of the elastic rubber cup with gas pressure, and the other is the floating support of the rubber ring supplemented by liquid. For spherical polishing where the support surface is flat, convex or small sagittal high and deep concave spherical surface, the use of flat cups or corresponding liquid floating tooling can meet the requirements and make it evenly stressed. However, when the supporting surface is a high-deep concave ball surface, due to the limitation of the elastic deformation of the rubber cup and the elastic rubber s...
