Mar 28, 2002· Ductile grinding streaks on aspherical glass surfaces were obtained by using a new precision machine and good grinding conditions. Fig. 7(a) shows ductile grinding streaks. An enlargement of the ductile streak as shown in Fig. 7(b) is a clear indication of material displacement. With these ductile grinding streaks, the polishing time was reduced by 50%, from 8 to 4 min.
