在光学玻璃的生产中,玻璃块料的制备是非常重要的环节。分割出来的玻璃块经振动磨削、洗净,然后逐个由工人在药物天平上称重,按重量大小进行分选。由于工作量大,不易保证分选精度。为了保证型料出厂质量,往往只好把型料的分选精度提高,这样就会把一部分合格品误认为不合格品,大大地浪费了人力和物力。目前照相机用光学镜片的生产发展很快,要想适应这一形势,中小批量的光学玻璃生产需采用国外先进的型料精化技术,但其中玻璃 In the production of optical glass, the preparation of glass block is a very important part. Divided out of the glass block by vibration grinding, washed, and then one by one by the workers weighing on the drug balance, according to the size of the weight sorting. Due to heavy workload, not easy to ensure the accuracy of sorting. In order to ensure the quality of the finished material, often have to improve the sorting accuracy of the material, so that some will be mistaken for nonconforming quality products, greatly wasting manpower and material resources. At present, the production of optical lenses for cameras has been developing rapidly. To meet this situation, the production of optical glass in small and medium-sized batches requires the use of advanced molding technology in foreign countries. However, glass
