| Outline of Final Research Achievements |
We have developed that unconventional processing technique with permanent magnet tool trapped in air by meissner effect and flux pinning by YBCO superconductor. Fist of all, this research had been proposed as sand blast processing by superconductive powder body accelerated by magnetic field after the superconductor powder grain is magnetized by field coolness process of the superconductor from electric magnet. Our new method can be applied to process against materials at room temperature although the sand blast processing using superconductors powder grain need to keep the lower temperature under superconductive transition point temperature because of the superconductor magnetization. This trapped magnetic tool at air becomes possible to reduce intervention of a tool during 2D or 3D processing and the applicability to the hollow processing can be expected. In our study, magnetic polarity of a permanent magnet was optimized to process against SUS and Cu materials.
