Machining Material Ti-6Al-4V (Grade 5) Titanium Ti-6Al-4V (ASTM Grade 5) is an alpha-beta titanium alloy with 6% aluminum and 4% vanadium . It has a hardness of 32 HR C and a Machinability rating of 20% . It is the most widely used titanium alloy due to its excellent strength-to-weight ratio and superb corrosion resistance. About 70% of all the titanium usage in the industry is of Ti6Al4V (or its sub-grades)
Primary uses of Ti-6Al-4V (ASTM Grade 5) :
Medical implants and prostheses. Structural aerospace components. Jet engine parts (In the cold section of the engine) Marine and chemistry parts. Machining Titanium Ti-6Al-4V is challenging because :
Very low heat conductivity leads to quick over-heating of the cutting edge . High hardness of 32 HRC leads to premature wear. Best practices for Machining Titanium Ti-6Al-4V:
Make sure your coolant is pointed to the cutting edge , and use a coolant pump with high flow and pressure rates. Medium and Roughing: Use a cutting edge with aggressive rake angles and high relief angles to avoid tearing or smearing the titanium workpiece material, preferably ground and with a small honing size.Finish operations: Use ground inserts/tools with sharp cutting edges and minimal honing size. Supper-finish operations : Consider using cutting tools designed for aluminum (very sharp, polished, and without honing).Summery:
Use inserts/tools with a very hard substrate and a very thin coating layer or uncoated inserts. For detailed carbide grades recommendations , check the Below Chart , or use the Grades Wizrad . Recommended Cutting speed range for turning at stable conditions is 230 - 300 [SFM] / 70 - 90 [m/min]. Recommended Cutting speed range for milling with stable clamping and short overhang is 160 - 230 [SFM] / 50 - 70 [m/min] For detailed cutting speed recomendations , check the Below Table , or use our Speed and Feed Calculator .
