Abstract

The invention provides a lapping and polishing method based on thermal accelerated corrosion, which mainly solves the problems of high cost and low processing efficiency for current processing of optical elements, especially aspherical optical elements. The optical element processing method based on thermal accelerated corrosion comprises the following steps: 1. determining a processing target shape; 2. determining the amount to be removed for points on a surface of a workpiece to be processed according to the determined target shape and the shape of the workpiece to be processed; 3. setting the temperature and the dwell time of corrosion liquid on the points on the workpiece to be processed according to the amount to be removed for the points on the surface of the workpiece to be processed determined in step 2; 4. performing corrosion to obtain the processing shape determined in step 1. The method of the invention is high in efficiency and low in cost.

Description

technical field [0001] The invention relates to a grinding and polishing mechanism, which is suitable for high-efficiency processing of aspherical optical elements. Background technique [0002] Aspherical optical components have many advantages such as correcting various aberrations, improving imaging quality, simplifying optical systems and expanding the field of view, etc., and have been widely used in many optoelectronic products in military and civilian fields. However, the processing of aspheric optical components still has problems such as expensive equipment, low precision, and low efficiency, which seriously restricts the development of related industries and scientific research projects. [0003] Small grinding head polishing technology is a quantitative polishing technology proposed for the processing difficulties of aspheric surfaces. Due to the deterministic and extensive nature of its processing, this technology has become the main processing method in major o...
