The requirement of producing metallic micro-parts for micro-machine and/or micro-mechanism will be increased. The study deals with manufacturing of tiny parts in mm-size by use of micro-machining technique of an ultra-precision milling machine. The ultra-precision milling machine, consisting of Z-motion table, positional spindle on it as C-rotational axis, X-motion table, is equipped with a pseudo-ballend mill composed of a single crystal diamond tool mounted at the top of high speed air spindle on X-motion table. A new manufacturing procedure is devised to manufacture a propeller of 3 mm in diameter as an example of micro-parts by use of ultra-precision milling machine. On the basis of CAD data of a propeller, two kinds of NC data, for front face and back one, are generated to machine the whole shape together with preparation of jig. It is found that the machined propeller mounted to the micro motor shaft works.
