Titanium alloys, which are often used in industries such as aerospace and chemicals, have a high strength-to-weight ratio and offer superior corrosion resistance. The exceptional biocompatibility of commercially pure titanium, along with some specific titanium alloys, such as Ti-6Al-4V, makes it ideal for medical devices as well. However, cutting titanium can be highly difficult, as it has low thermal conductivity. As high temperatures are often generated during the cutting process, the heat is unable to dissipate through the material and instead collects at the cutting point, leading to chipping and reducing tool life.
The key to easily machining titanium lies in using the right cutting tools, speeds, and feeds, depending on the alloy type.
