Abstract
In order to realize the actual use of micro machines, it is important not only to make machine elements consisting of micro machines precisely but also to establish manufacturing process for micro machine elements having sufficient functions. From such a viewpoint, this study aims to consider the manufacturing technology for micro machine elements and to propose a new concept for micro machine elements. As the first stage of this study, a manufacturing technology of micro size bolts as a machine elements widely used is considered. In order to discuss the manufacturing technology of bolts less than 1mm, performances test of ordinary size bolts are carried out. On the other hand, a small size NC lathe for micro bolts is developed.
