Development of Cutting Technology in Strong Alkaline Water

Recently titanium and nickel alloys have become eminent for making aeronautic and astronautic parts. Since both titanium and nickel alloys have very low thermal conductivity, the tool will be suffered from a huge damage by the generated heat during machining process. It is required for a durable tool with excellent cooling capacity. Therefore, in this research, cutting technology in strong alkaline water for machining of titanium and nickel alloys was developed and evaluated. Before cutting experiment, the corrosion resistance for titanium alloy and other materials were investigated. Then this cutting process was performed for evaluation in the vessel with strong alkaline water. The assayed materials were mainly Ti6Al4V. The cutting conditions were investigated in experiments. It is concluded from the results that; (1) The cooling capacity using strong alkaline water is very effective to maintain the cutting potential of tool, (2) The new tool is effective for high speed cutting of titanium alloys and nickel (3) The new tool and compulsory cooling system are economical and eco-friendly.
