Embodiment Construction
[0018] The present invention will be further described in detail below with reference to the accompanying drawings.
[0019] like figure 1 As shown, a fixed abrasive polishing head of the present invention is mainly composed of a fixed abrasive polishing layer 2, a fixed abrasive polishing pad layer 3, a fixed abrasive polishing head base 4 and an installation hole 5, and the entire fixed abrasive polishing head 1 is in the shape of a round cake , the fixed abrasive polishing pad layers 3 are evenly distributed on the edge surface of the fixed abrasive polishing head base 4 at equal intervals, and the distance between every two fixed abrasive polishing pad layers 3 is equal. On the polishing head base 4, the fixed abrasive polishing layer 2 is fixed on the surface of the fixed abrasive polishing pad layer 3 by gluing, and the number of the fixed abrasive polishing layer 2 is equal to the number of the fixed abrasive polishing pad layer 3, and the fixed abrasive polishing layer...

The invention discloses a fixed abrasive polishing head and a polishing method thereof, which relate to the field of optical machining and solve the problems of complicated polishing head manufacturing technology and low polishing accuracy existing in an existing mechanical small tool polishing method. The fixed abrasive polishing head comprises a fixed abrasive polishing head substrate, an installation hole, fixed abrasive polishing cushion layers and fixed abrasive polishing layers, wherein the fixed abrasive polishing head substrate is in a round cake shape, the installation hole is formed in the center of the fixed abrasive polishing head substrate, the fixed abrasive polishing cushion layers are equidistantly and uniformly distributed on edge surfaces of the fixed abrasive polishing head substrate and are fixed through gluing, and the fixed abrasive polishing layers are fixedly arranged on the surfaces of the fixed abrasive polishing cushion layers through gluing. According to the fixed abrasive polishing head disclosed by the invention, the manufacturing technology is simple, and the use is more convenient and reliable; the fixed abrasive polishing head is adopted for polishing an optical aspheric element, optical aspheric elements in different shapes and calibers can be effectively polished, a reliable polishing technology can be quickly formed, a stable removal function can be obtained by controlling a polishing contact area during a polishing process, and the polishing efficiency and the polishing accuracy are effectively increased.
Description
technical field [0001] The invention relates to the technical field of optical processing, in particular to a fixed abrasive polishing head and a polishing method thereof. Background technique [0002] With the improvement of optical system requirements, better imaging quality, fewer optical components, simpler and lighter optical systems, etc. have become the future development trends, and optical aspherical components that can meet the above requirements are also getting more and more Wide range of applications. Therefore, higher requirements are also put forward for the processing and manufacture of optical aspherical components. It is particularly important to improve the processing efficiency of optical aspherical components and reduce processing costs. [0003] The manufacturing process of optical aspherical components is mainly divided into two parts, one is aspherical milling and shaping, and the other is aspherical polishing and smoothing to obtain a surface shape ...
