Embodiment 1

[0037] Use this method on the PR-150 prism milling machine to process the L-shaped notch with the following precision:

[0038] ●L-shaped notch step thickness 4±0.02;

[0039] The parallelism between the two sides of the L-shaped notch step is 0.01;

[0040] ● L-shaped notch width 17 ± 0.05.

[0041] The process of processing is as follows:

[0042] (1) Clean fixtures and parts to be processed.

[0043] (2) To bond the parts, place the fixture and the processed part on the electric heating plate, slowly heat it to the temperature 70 ℃ ~ 80 ℃ where the glue strip wax can just melt, and coat the bonding surface of the fixture and the processed part with a A thin and uniform layer of wax strips, place the processed parts on the fixture, and align the edges.

[0044] (3) Naturally cool to room temperature.

[0045] (4) It is processed by a prism milling machine. The processing state is that the rotation center of the grinding wheel is consistent with the central axis of the p...

Abstract

The invention relates a method and clamp used to process non- rotary L type gap on the optical lens. It exploits the existing optical numerical control equipment prism milling machine, uses the ex-circle and end face of diamond grinding wheel to process high precision non rotary L type gap step, designs out proper clamp to make the process usual. The grinding wheel end face can be used to process one side and grind out platform by its outside diameter at the same time to form L type gap.

Description

technical field [0001] The invention belongs to the optical manufacturing technology and relates to a method for processing a non-revolving L-shaped notch on an optical lens. Background technique [0002] If the step is a circle, that is, a rotating body, after processing the outer circle on the laser centering edging machine, change the coordinates of the program reference point to grind out the step. By measuring the actual step thickness and correcting the program, the thickness of the step can be guaranteed. Moreover, the outer circle and the steps are clamped once, which ensures the parallelism between the steps and the bottom surface. However, its disadvantage is that it can only process rotary circular steps, and cannot process non-rotary L-shaped notches. Contents of the invention [0003] The purpose of the invention is to process a non-revolving L-shaped notch meeting the requirements on the optical lens. [0004] The technical solution of the present invention...
