Some things to be aware of when cutting

Due to the small elastic modulus of titanium alloy, the clamping deformation and force deformation of the workpiece in the processing will reduce the processing accuracy of the workpiece; Chlorides in the cutting fluid may also be used to break down or volatile toxic gases, when used should take safety precautions, otherwise should not be used;
If a hydrogen-containing cutting fluid is used, hydrogen is released by decomposition at high temperatures during cutting, and hydrogen brittle is caused by titanium absorption;
It may also cause high temperature stress corrosion cracking in titanium alloys. Workers and fixtures made from lead or zinc-based alloys are prohibited from contact with titanium alloys, as are copper, tin, cadmium and their alloys. Chlorides in the cutting fluid may also be used to break down or volatile toxic gases, when used should take safety precautions, otherwise should not be used;
In general, when cutting titanium alloy, there is no risk of fire, only in the micro-cutting, cutting the small chips to fire and burn phenomenon.
In order to avoid fire, in addition to pouring a large amount of cutting fluid, should also prevent chip accumulation on the machine, tool blunt immediately after replacement, or reduce the cutting speed, increase the feed to increase the thickness of the chip. If the fire, should use talcum powder, limestone powder, dry sand and other fire extinguishing equipment to put out, the use of carbon tetrachloride, carbon dioxide fire extinguishers, can not be watered, because water can accelerate combustion, and even lead to hydrogen explosion.
