Recently, vibration of some machine tools have become a serious problem because of improving surface roughness and machining accuracy of a work piece and reducing noise in a machine shop. Therefore, in this paper, at first, we have developed a powder composite damper in order to improve the structural properties of machine tools. The damper consist of coarse powder at 60% in volume, intermediate powder at 24% in volume, fine powder at 10% in volume and an air at 6% in volume respectively. The dampers were composed in the space of the machine tool structure. Then, the powder composite damper was evaluated in the experiment using some steel boxes and C frame type of punch press. It is concluded from the results that; (1) the powder composite damper has high damping vibration and high static stiffness at the same time. (2) sintered alumina was effective as a material of the damper (3) the C-frame type of punch press with the powder composite could reduce noise and vibration.
