Obviously, grinding-milling with a grinding depth of 1 μm creates a desirable fine surface (see Fig. 10 (a)-(1)). This indicates that such a grinding depth accomplishes a ductile machining regime on quartz glass. Extending the grinding depth to 2 μm increases material removal; however, brittle fracturing begins to appear (see Fig. 10 (a)-(2
