Description

Technical Field

[0001] The present invention relates to the technical field of optical processing, and particularly relates to a layered fixture system for a micro-jet machining tool for small-aperture reflectors. Background Art

[0002] As one of the core components of remote sensing satellites, aspherical optical elements are an important factor restricting the mass production of satellites at the present stage. Among them, the processing of small-aperture reflectors is relatively difficult. The difficulty lies in that a polishing tool with a fixed size can remove the low-frequency components in the surface shape error whose wavelength is greater than 0.6 times the tool diameter. For tools of the same size, the proportion of the remaining error frequency band width of small-aperture reflectors is much larger than that of medium- and large-aperture reflectors. Therefore, an effective way to improve the processing ability of the middle and final stages of small-aperture reflectors is to find a processing tool with a diameter ≤ 2 mm and a sufficiently stable removal efficiency ≥ 80%. At the same time, the processing equipment is the carrier of the processing technology, and the research on processing technology needs to be combined with the development of processing equipment.

[0003] Based on the above technical problems, those skilled in the art urgently need to develop a layered fixture system for a micro-jet machining tool for small-aperture reflectors that can complete the clamping work of square and circular reflectors with different apertures and can adapt to polishing liquid recovery pipes with multiple installation heights.
