Ultraprecision Ductile Grinding of Optical Glass Using Super Abrasive Diamond Wheel

摘要: In this paper, a novel conditioning technique features using copper bonded diamond grinding wheels of 91μm grain size assisted with ELID (electrolytic in-process dressing) as conditioner to precisely and effectively condition nickel electroplated monolayer coarse-grained 151μm was firstly developed. Under optimised parameters, the super abrasive wheel well conditioned in terms minimized run-out error flattened surfaces constant peripheral envelope, force monitored by transducer modified surface status in-situ coaxial optical distance measurement system. Finally experiment on BK7 conducted corresponding morphology subsurface damage measured AFM (atomic microscope) SEM (scanning electron respectively. The experimental result shows that newly developed is applicable feasible ductile glass featuring nano scale roughness, indicating prospect introducing into machining brittle materials.
