Abstract
The high precision technology for small optical components has been already established in the optical manufacturing fields. On the other hand, in recent year, the high precision geometric shape and surface roughness are required for large glass components molding process. In the comparing of a glass optical component and a metal one such as aluminum, the cost of glass optical component is lower than metal one. In this research, the polishing process of stainless steel molding dies that are used to form thin glass components is investigated. As a result, a stainless steel molding die surface are polished to the surface roughness of below 200 nm(P-V) with 0.5% - alumina polishing liquid. Then, in the case of a polishing process with only own weight of molding die and polishing pressure of 0.5 kPa, those polishing time is approximately 60 hours and 20 hours respectively.
