Research Summary

Hitoshi  Ohmori(D.Eng.)

The main objective of our research is the development of revolutionary and new material processing technologies in grinding, lapping, polishing, cutting and forming for an extensive range of materials. Through advanced research activities on ultraprecision, ultrafine, nanoprecision and ultra-smooth machining processes, required for the fabrication of advanced functional devices such as optical and electronic components, we launched the research of a new field of micro-mechanical fabrication technologies in addition to surface functional modification, transcription, process control and optimization techniques, aiming at a wide variety of materials, precision, mechanics and scale ranging from micrometer to nano/pico meter level, to meet practical and applied industrial needs.
