Drilling of titanium alloys make high demands on the cutting fluids, the cutting strategies and the cutting tools in use. Due to the low thermal conductivity of titanium alloys, a great proportion of the heat generated during the cutting process has to be removed through the cutting tool. This leads to a high thermal tool load and results in elevated tool wear.
In consequence of the process the accessibility for cutting fluid is limited during drilling. A conventional flood cooling is only able to remove a small amount of the generated heat. This is a problem especially when drilling deep holes, resulting in high tool temperatures which lead to premature tool failure. This problem can be solved by the use of an internal high-pressure lubricoolant supply. However, the success of this technology strongly depends on the lubricoolant supply pressure and volume flow as well as the position of the nozzles for cutting fluid supply.
