Shown in fig. 1 are several typical polygonal laser scanning mirrors. Polygonal laser scanning mirrors have become a core part of the next generation of high-speed scanning technology.
The machining of the polygon scanning mirror is currently generally realized by a traditional polishing method and single-point diamond turning, and the two methods have advantages and disadvantages respectively. Wherein, the surface roughness of the scanning mirror processed by the traditional polishing method is lower, and the surface roughness after polishing can be reduced to
However, the polishing method has a limited range of materials, for example, the polishing method cannot be directly used for processing an aluminum mirror, and since the surface of the aluminum mirror is very sensitive to scratches during the polishing process, although a new polishing method is developed for the aluminum mirror, the material removal efficiency is still low. Compared with the traditional polishing method, the single-point diamond turning method has higher mirror surface roughness after processing, and the surface roughness value of the processed scanning mirror is generally larger than that of the processed scanning mirror
But the single-point diamond machining efficiency is very high, and the single-point diamond machining method is very suitable for machining materials such as aluminum, copper and plastics. Therefore, single-point diamond turning is a main method for machining a polygonal laser scanning mirror, and for example, toshiba machinery corporation develops special cutting equipment for machining the polygonal laser scanning mirror to realize efficient and high-precision machining thereof. Machining of polygonal turning mirrors was also accomplished using single point diamond turning Technology, Symons Mirror Technology, uk. The specific technical details of the diamond turning process of the polygon scanning mirror of two companies are not reported in public.
However, the efficiency of conventional polishing methods and single point diamond turning processes still needs to be further improved.
