Abstract

The invention discloses a liquid injection polishing method, which is characterized by the following: accelerating the abrading particle through high-pressure pump; spraying the abrading particle through nozzle on the workpiece surface to generate collision; polishing the workpiece surface; adapting the normal line of manufacturing domain center as axle to make nozzle and workpiece rotate relatively; letting the separation angle of nozzle pipe axle and tangent plane of manufacturing region center range from 30 to 90 deg and d as nozzle internal diameter. When the separation angle is 90 deg, the distance between intersection point of pipe axial elongation line and workpiece surface and manufacturing region center is from 0.5d to 1d; when the separation angle is less than 90 deg, the distance between intersection point of pipe axial elongation line and workpiece surface and manufacturing region center is from 0.2d to 1d. The invention can obtain ideal removal function to realize digital control polish, which is fit for optical manufacturing.

Description

technical field [0001] The invention relates to an optical polishing process, in particular to a liquid jet polishing method, which is especially suitable for the polishing treatment of optical elements. Background technique [0002] Liquid jet polishing technology is a new optical polishing process, which relies on the high-speed flowing liquid and the abrasive particles carried by it to scour the surface of the workpiece to achieve the purpose of polishing. Compared with the traditional polishing technology, the advantage of liquid jet polishing is that the processing tool is liquid, there is no wear of the polishing disc, the removal function remains constant, and the surface accuracy is easy to control; at the same time, because the polishing liquid is constantly Circulating flow can keep the temperature of the polished workpiece constant, and can also automatically remove the processed debris; moreover, the polishing head is realized by a small...
