在光学零件的加工中,各种平面镜的平行差都要通过改平行这道工序来保证,而改平行这道工序大都采用单件手工操作,劳动强度大,效率也低。随着我国光学生产的日益发展,光学零件的生产不但要求数量多,而且要求质量高,单件手工修改平行差的生产就远远满足不了需要。为了解决这个问题,曾多次进行成盘修改平行差的实验,终于获 In the processing of optical components, the parallelism of various plane mirrors must be ensured by changing this procedure. However, most of the procedures of parallelizing this procedure are single-handed manual operation, which results in high labor intensity and low efficiency. With the development of optical production in our country, the production of optical components not only requires a large number of products, but also requires high quality. The production of optical components can not satisfy the need of manual modification. In order to solve this problem, we have repeatedly conducted experiments to change the parallelism and finally won
