玻璃碳由于其热稳定性而广泛用于高温熔融工艺，例如石英。在玻璃模压（GMP）光学透镜加工中，玻碳材料的脆性是超精密加工的主要障碍。为此，分别采用车削和磨削工艺对玻碳材料进行了延性加工研究.实验结果表明，超精密车削表面在所有加工条件下均表现为脆性断裂，超精密磨削表面在切屑厚度较小的条件下表现为半韧性断裂。
Glassy carbon is widely used for high temperature melting process such as quartz due to its thermal stability. For utilizing Classy Carbon to glass mold press(GMP) optical lens, brittleness of Glassy Carbon is main obstacle of ultraprecision machining. Thus authors investigated ductile machining of Glassy Carbon adopting turning and grinding process respectively. From the experiments, ultraprecision turning surfaces resulted brittle crack in all machining conditions and ultraprecision grinding surfaces showed semi-ductile mode in small undeformed chip thickness conditions.
