What precautions should be taken when cutting titanium materials?

When cutting titanium materials, attention should be paid to the following characteristics of titanium:

(1) Titanium has a high friction coefficient, and the chips are prone to generate high temperatures during cutting, which accelerates tool wear;

(2) The thermal conductivity of titanium is small, and the chips are tough and not curly. The heat generated by friction with the cutting edge is almost entirely concentrated on the blade and the forward inclined surface of the tool, causing the blade to burn out. Therefore, the feed amount should not be too small, and the cutting speed should not be too high, otherwise it is easy to stick to the tool and burn fine titanium chips, causing accidents;

(3) Due to the small elastic modulus of titanium, it is prone to bending during deep cutting of fine workpieces, and the workpiece is prone to leaving the tool. Therefore, it is necessary to install an anti vibration frame during processing;

(4) Titanium has high-temperature activity and is prone to surface contamination during processing;

(5) Due to the presence of high hardness oxides, nitrides, and carbides in titanium, it is easy to cause rapid wear of cutting edges during cutting;

(6) When cutting titanium, the cutting force is small, and cutting is not easy to produce tool marks, so it is possible to perform machining with high surface smoothness.
