In the 21st century, as it is important to produce the products with high accuracy, high quality and eco-friendly, the most of manufacturers need several daring plans, unique ideas and new technologies. For example, in machine tool technology, restraint of vibration on the machine tool was required for high accuracy and quality, and several countermeasures using costly equipment and large quantity of electrical energy were used for the restraint, however those countermeasures are not enough. Therefore a machining using alkaline water with polymer for decreasing vibration of machine tool was investigated. Relationships between the mixed polymer in the alkaline water and the damping ratio or coefficient of friction were firstly investigated. Corrosion resistance of alkaline water was also investigated. Then effect of alkaline water with polymer for restraining vibration during cutting was calculated by FEM simulation. The effects of alkaline water with polymer were lastly evaluated regarding noise and vibration on a machine tool, surface roughness on a work piece and the tool life in the experiment. It is concluded from the results that; (1) The optimum percentage of the polymer for the damper was 6 wt%, (2) There are the corrosion resistance of several materials without aluminum, copper and their alloys in alkaline, (3) Vibration during cutting was restrained by alkaline water with polymer.
