近年来随着复印机的国产化,复印机光学箱体中的光学零部件同其它零件一样,在国产化过程中遇到了很多工艺难题。我厂生产的友谊牌BD-5511型复印机光学箱体中的反光镜就是一例。该反光镜采用国产浮法玻璃为材料,其规格为290×50×6(mm),反光镜长厚的比值在0.02左右。镜面鉴别率要求满足3号鉴别率板第20组,约为6″。我们在加工过程中采用了许
In recent years, with the localization of photocopiers, the optical components in the photocopier optical box are the same as those of other parts, and many technological difficulties have been encountered in the process of localization. My factory production of friendship card BD-5511 copier optical box in the mirror is an example. The reflector made of domestic float glass for the material, the size of 290 × 50 × 6 (mm), the length of the mirror ratio of about 0.02. Mirror recognition rate to meet the No. 3 identification plate 20th group, about 6 ". We used in the processing of Xu
