Tackling Titanium

摘要

Titanium is a reactive metal used for making parts. Other reactive metals include magnesium, hafnium, zirconium and depleted uranium. The reactive metals are pyrophoric, creating potential fire hazards. Special precautionary measures allow managing this problem, such as applying large quantities of cutting fluids, having an argon or nitrogen atmosphere and maintaining a Class D fire extinguisher for emergencies. Titanium alloys are considered difficult-to-machine metals, especially when facemilling. To manage this problem, the following data should be considered: Titanium alloy properties, Principal geometry of facemills, Suitable cutting tool materials, Machining parameters, and Coolant application.
