概要

Fabrication of one tooth micro ball endmill with sharp cutting edge without chips was conducted using various sintered materials as a tool material. Electroplated diamond tools and a resin-bonded diamond wheel #32000 mesh size were employed for the roughing and finishing of the tool fabrication, respectively. As to the roughing of a PCD tool, EDM using electroplated diamond tool as a cathode was conducted. It was verified through the experiment that sharp cutting edge without chips could be fabricated to the tool materials under 20GPa Hv in hardness by using a resin-bonded diamond wheel for the finishing. As to the cBN and PCD, cutting edge without chips could not be obtained when using electroplated diamond tool was adapted for the finishing.
