本刊82年5期中已介绍了罗马尼亚眼镜片加工简况,下面介绍罗国该厂中等精度透镜的加工情况。一、玻璃的坯料大、中批量生产用的坯料均为型料,小批量生产采用块料。块料切割采用瑞士 Meyer-Buger 厂产的 QS2型切割机,也有采用西德 BOTHNER 厂产的切割机切割的,另外有自制的大型切割机。玻璃滚圆采用西德 Dama 厂产的 RFM 型滚圆机。二、上盘精度较低、批量较大,中心厚度允差大于±0.1
In this issue, we have introduced the processing of Romanian ophthalmic lenses in the first five years of 1982 and introduced the processing of medium precision lenses at this factory in Romania. First, the glass billet large, medium-volume production of billets are expected, low-volume production of block materials. Block cutting using the Swiss company Meyer-Buger QS2 cutting machine production, but also with West Germany BOTHNER factory cutting machine cutting, in addition to homemade large cutting machine. Glass rounding using West Germany Dama factory production RFM-type spheronization machine. Second, lower the accuracy of the plate, the larger batch, the center thickness tolerance greater than ± 0.1
