Problems solved by technology

[0003] The traditional edging method is to use the grinding tool on the edging machine to directly grind according to the required size, so the effect of edging is not good, and many small chippings will occur on the inner opening of the lens, which seriously affects the lens. service life

Embodiment Construction

[0014] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples, which are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0015] This embodiment provides an optimization process for lens edging, and the lens is edged according to the following steps:

[0016] a. Initial edging: In the process of initial edging, there is a reserved size for the platform surface of the lens, and an edging machine is used to first grind the lens;

[0017] b. Fine grinding: Use a fine grinder to finely grind the reserved size to get the finished product after grinding;

[0018] The reserved size described in step a is 0.05mm~0.15mm, preferably 0.10mm.

[0019] The specific operation process of step a is to absorb and hold the processing center of the lens on the chuck of the edging machine, or press from both sides of the lens to clamp t...

Abstract

The invention discloses an edging optimization process for a hollow hemispherical lens, which is capable of carrying out edging on the lens according to the following steps of a, preliminary edging, that is to say, providing a reserved size on a concave platform surface of the lens in a process of preliminary edging, and carrying out preliminary edging on the lens by adopting an edging processing machine; b, accurate edging, that is to say, carrying out accurate grinding on the reserved size by adopting a fine grinder so as to obtain a finished product after edging, wherein the reserved size of the platform surface in the step a is 0.05 mm to 0.15 mm. According to the edging optimization process, edging is carried out on the lens by adopting the steps, so that the degree of finish of the lens is improved, thus the surface of the lens is smoother, and meanwhile, the condition of small edge breakage generated by an inner mouth after edging is avoided, so that the service life of the lens is prolonged.

Description

technical field [0001] The invention relates to the technical field of lens processing, in particular to an optimization process of lens edging. Background technique [0002] In the lens manufacturing process, edging plays an important role in the lens processing process. The so-called edging mainly refers to grinding the circular lens so that it can be embedded in the frame that needs the lens, such as a camera. [0003] The traditional edging method is to use the grinding tool on the edging machine to directly grind according to the required size, so the effect of edging is not good, and many small chippings will occur on the inner opening of the lens, which seriously affects the lens. service life. Moreover, the surface of the lens platform is relatively rough and the finish is poor, so such an edging process is very bad. It is an urgent problem to be solved at present to develop an edging method that improves the lens finish and service life. [0004] Therefore, the a...
