Magnetic levitation tool is the machine that magnet levitates above superconducting bulks and driving force of rotating magnet shaves the object. This tool is expected to use for a grinding machine and machining device because of hollow machining and micromachining by strong fixing. For using magnetic levitation tool, the attractive force, the repulsive force and rotating torque are important for grinding machine, machining outer surface and both, respectively. These forces are calculated by FEM, and compared with experimental results. The experimental results are agreed well with calculated results. However, the attractive force is one order smaller than that required in chemical mechanical polishing.}, pages = {012048-1--012048-5}, title = {Evaluation of Magnetic Cutting and Polishing with Superconducting Bulks}, volume = {871}, year = {2017}, yomi = {オタベ, エドモンド ソウジ and キウチ, マサル} }
