DC pulse type bielectrode microminiature grinding and polishing tool

Abstract

The invention provides a DC-pulse-type dual-electrode micro-miniature grinding and polishing tool and belongs to the field of the optical surface processing tool. The invention aims to design a point-contact-type integrative miniature deterministic grinding and polishing tool. The polishing tool is composed of a puller bolt, a casing, a battery, a circuit board and electrodes. Pulsed high voltage is outputted to two needle electrodes of a positive one and a negative one by an oscillation circuit system, the rheological liquid of the high voltage field ionization between the positive and the negative electrodes generates the rheological effect, the apparent viscosity is significantly enhanced and aggregation occurs. The particulate grinding material capable of grinding and polishing is in discrete distribution between the two needle electrodes to form a chain structure, the relative movement between the combined tool and the processed workpieces achieves the removal of the material on the workpiece surface and the purpose of fine grinding and polishing. The grinding and polishing machine is applicable to ultra-precise processing of the small-caliber optical heterotypic curved surfaces.

Description

technical field [0001] The invention relates to a DC pulsed double-electrode miniature grinding and polishing tool based on the electrorheological effect, which belongs to the field of optical surface processing tools. Background technique [0002] The application of optical components in optical fiber communication, national defense, medical treatment, office automation and other fields is becoming more and more extensive. Technology is becoming more and more important. In order to meet the needs of the development of multimedia network communication technology in the future, it is necessary to seek new breakthroughs in the manufacturing technology of optical components. Optical aspheric microlenses are a typical example. Aspheric mirrors have the advantages of correcting aberrations, improving image quality, and expanding the field of view, and can improve the resolution of the optical system, simplify the structure, and reduce the weight. However, compared with tradition...
