According to the properties of titanium alloy and the characteristics of the cutting process, the following aspects should be considered in the processing of titanium tube:

Use carbide tools as far as possible, such as tungsten cobalt carbide and titanium alloy chemical affinity, good thermal conductivity, high strength. Ultra-fine grain carbide with impact resistance can be used for intermittent cutting at low speed. High speed steel with good high temperature performance can be used for forming and complex cutting tools. A smaller front Angle and a larger back Angle are adopted to increase the contact length between the chip and the front cutting surface, and reduce the friction between the workpiece and the back cutting surface. Keep the blade sharp to ensure smooth chip discharge and avoid chip collapse. Cutting speed should be low to avoid high cutting temperature; Moderate feed, too big easy to burn the knife, too small because the blade in the work hardening layer wear too fast; The cutting depth can be larger, so that the tip of the tool in the hardening layer below the work, is conducive to improve the tool durability. Cooling fluid must be added during processing to allow sufficient cooling. When cutting titanium alloy, the tool resistance is large, so the process system must ensure that there is enough rigidity. Because titanium alloy is easy to deform, so cutting clamping force can not be large, especially in some finishing process, when necessary to use a certain auxiliary support. These are the general principles to be considered in titanium alloy processing, in fact, with different processing methods and under different conditions there are different contradictions prominent points and focus to solve the problem.
