加工物镜44的流水线车间有六条1流水线和三条2流水线,有五个物镜零件的七个表面在这些流水线上加工(见表1),其余的五个曲率半径较大的表面在流水线3上加工。流水线加工顺序见图1。为了便于加工,将毛坯的第一面粘入镜盘里,首先磨好第二面,以便得到定位基准,借助于浸有树脂5的棉纱细布垫在装置3上进行粘接上盘。镜盘的加热温度为(115±5)℃,透镜加热温度为(50±5)℃,上胶时间为0.5～5分钟,其时间长短与镜盘的大小有关(单个透镜约需
The line shop that processes the objective lens 44 has six 1 and 3 2 lines with seven surfaces of five objective parts machined on these lines (see Table 1) and the remaining five surfaces with larger radii of curvature are machined on line 3 . Pipeline processing sequence shown in Figure 1. For ease of processing, the first side of the blank is adhered to the mirror plate, and the second side is first ground to obtain the positioning reference. The upper plate is bonded to the device 3 by means of a cotton cloth impregnated with the resin 5. The heating temperature of the mirror plate is (115 ± 5) ° C, the heating temperature of the lens is (50 ± 5) ° C, and the coating time is 0.5 to 5 minutes, the length of which depends on the size of the mirror plate
