| Research Abstract |
The purpose of this study is to develop the polishing technology of performing the accuracy with nano-meter level and the surface roughness with the sub-nano meter level for mold of small-diameter lens by controlling with a magnetic field utilizing a magnetic compound fluid(MCF). In this study, it was clarified that the rotating concave surface having small diameter is enabled to be polished by the only two-dimensional motion of the polishing tool under the application of a pulsed magnetic field. In the case of pulsed magnetic field, the flat surface is more flattened and smoothed over a wide surface. The form accuracy of the concave surface having small diameter at the pulsed magnetic field is maintained more smoothly.
