Machining Titanium
Machining Titanium
(OP)
I am going to drill a 0.5mm diam. hole (In the vertical machining Centre) on a titanium bar(Ti 6Al 4V ELI). Now I am asking for a advise for machining that titanium( Also I need a help for the selection of the drilling tool material to machine the titanium. If you have a knowledge or any experience on this issue, I will be happy for sharing them.
Kind Regards,

Although my only practical experience in machining titanium comes from milling, we found that the coated mills, like TCN or TiAl would wear (probaby abrasive wear from being the same metal) down much faster than the non-coated HSS or carbide types.

I would make sure you have a good spot first. I would use a spotter, not a center drill, unless you are sure the face you will drill into is true. I prefer to use a Tin coated HSS drill, (that's just me), and calculate your feeds and speeds as per Machinery's Handbook. Pecking cycle is the way to go. Do not well in the material. Heat and cooling while cutting in 6-4 will give nothing but heartache. As it will shift from alpha to beta while you cut, and your feeds and speeds just went out the window. Good luck.

I have worked with Zirconium which is similar to Titanium.
The best tool would be TiN coated HSS. Continuous feed with lot of coolant will give best results.
