Ultra-Precision Grinding of Optical Glasses with High Surface Integrity Utilizing Fine and Coarse Grained Diamond Wheels
In order to search for the feasible ways to realize conventional and high efficient grinding of optical glasses in ductile material removal mode, the metal boned fine-grained diamond wheels, mono-layer electroplated nickel bonded coarse-grained (150μm) diamond wheel and hybrid copper and resin bonded fine-grained diamond wheel were applied in the grinding process of optical glasses on machine tools of Tetraform’C’, Nanotech 500FG and MGA1432A respectively assisted with ELID (Electrolytic In-Process Dressing). The results show that ultra smooth surfaces can be generated with surface roughness of Ra less than 10nm, and SSD (subsurface damage) depth less than 2μm. It indicated that good surface and subsurface integrity was realized in this study for optical glasses with conventional and high efficient diamond grinding techniques.
