3 Radius Optical Lens Processing Method

Abstract

The present invention has disclosed 3 radius optical lens processing methods. According to the following process, it is divided into two processing. The specific process is: milling, fine grinding, grinding edges, polishing, milling, polishing, coating; first processing; first processing: First, according to the requirements of the parts, the central thickness and tadpole tolerance requirements of the control to be controlled at a time should be reserved. The diameter of the R3 surface is increased during one processing. Generally, it is suitable for polishing.MM's arc height; secondary processing: process process mainly achieves grinding R1 surface to ensure total high growth. At the same time, control the R2 surface caliber within the required range.Suitable for on -site control, meet processing requirements, and suitable for mass processing.

Description

technical field [0001] The invention belongs to the field of manufacturing technology of optical parts, and in particular relates to a grinding process method of optical parts with three radii. Background technique [0002] The traditional lens has two working surfaces, and the traditional process uses three steps of milling, fine grinding and polishing. Through milling and fine grinding, the parts are controlled to meet certain roughness, surface shape (radius of curvature) and central thickness requirements, and the polishing process is used to control the parts to meet the requirements of surface shape (radius of curvature), appearance and other requirements of optical parts. The existing processing technology can only realize the processing and grinding of the left and right spherical surfaces of the lens. [0003] However, with the development of optical technology, multiple spherical lenses have appeared in order to meet the special optical path and structural require...

AI Technical Summary

Problems solved by technology

3 radii parts are a typical representative of them. 3 radii means that a total of 3 spherical surfaces need to be processed. The characteristic of this processing type is that one of the spherical surfaces has a diameter of only ￠10mm (D3), while the lens caliber is above ￠40mm (D1), which is normal. Unable to achieve processing, which has no precedent in lens processing before

[0004] In addition, one surface is added, but the relevant dimensions are increased by 3 or 4. How to use traditional equipment and testing equipment, how to control the vector height and total height in the grinding (fine grinding, polishing) process, how to formulate the process flow, and make the process simple and suitable for On-site control, suitable for batch processing, is the key to this technical field, because traditional technology methods cannot realize batch processing of parts with multiple radii
