金刚石精磨在西德是最近二、三年发展起来的,进展也较快。采用金刚石精磨在光学玻璃工业中是一个新的工艺。它是在抛光之前的一道精密工序,其玻璃的切削过程应考虑到粗磨的公差。使用金刚石模具进行精磨,可以产生光滑的表面,得到的光圈在N=2以内。当精磨余量在0.08～O.10mm的范围内时,精磨的时间只要几秒钟,很少超过两分钟的,一般都在一分钟以内完成。而抛光时,在抛光余量为5～10μ的范围内,不需要破坏精
Diamond grinding in West Germany is the last two or three years of development, progress is faster. Using diamond grinding in the optical glass industry is a new process. It is a precision process before polishing, and its glass cutting process should take into account the coarse grinding tolerance. Fine grinding with a diamond tool produces a smooth surface with an aperture of N = 2 or less. When the grinding allowance in the range of 0.08 ~ O. 10mm, the grinding time as long as a few seconds, rarely more than two minutes, usually within one minute to complete. Polishing, polishing margin in the range of 5 ~ 10μ, do not need to destroy the fine
