Abstract

Glass is one of the most important materials in the optical industries. The high efficiency ultra-smoothness grinding technique of the glass has been strongly required. To improve the productivity, in our previous researches, the newly devised ultra-smoothness grinding method is proposed. By applying the new method to the horizontal surface grinding1),2),3), the surface roughness of cemented carbide tool, silicon carbide ceramic and so on is found to attain below 30nm (Rz) or 5nm (Ra) in the measuring area of 256μm × 256μm. As a result, the new method is ascertained to be useful for finishing near the ultra-smoothness surface. In this report, ultra-smoothness grinding of a glass is examined. The specification of metal bond diamond wheel used is the grain size of #140 and the concentration of 50, respectively. The 3D surface roughness of glass formed using the suitable grinding condition attains about 27nm(Rz) or 1.4nm(Ra).
