概要

論文の詳細を見る
Fe-Cu-C sintered powder compact was used as a core of diamond rotary dresser in powder metallurgical process. The rotary dresser made by this method showed very excellent accuracy compared with the one made by conventional process. The sustaining of diamond grits by infiltrated tungsten powder seems to be better than the one made by conventional process.<BR>The damping capacity of composite material, tungsten powder and Fe-Cu-C sintered powder compact infiltrated simultaneously, was measured in comparison with other materials. The results showed that the above-mentioned composite material seems to be advantageous in its capability of resistance against abnormal vibration during the use of rotary dressers.
