MANUFACTURE METHOD OF ENDMILL TOOL

A manufacturing method for an end mill tool prepared by the present invention comprises: a processing preparation step for identifying a crystal direction of a natural rough diamond by structure inspection; a polishing step where a natural rough diamond is welded and combined into a first auxiliary body, and the lower base plane and the upper reference plane of the natural rough diamond are polished using polishing equipment; a grinding step where a processing tip separated from the first auxiliary body is welded and combined into the second auxiliary body, and then the edge of the natural rough diamond is ground using grinding equipment in order to complete the processing tip with a cutting edge; and a setting step where the processing tip separated from the second auxiliary body is temporarily installed in a cemented carbide body installed in setting equipment, the aligning state of the processing tip is adjusted, and then the processing tip is combined with the cemented carbide body in a room temperature solidification method using a room temperature bonding agent in order to complete an end mill tool.
