Lathe Boring Titanium?

[dertsap]

good choice , heat is the enemy , the sharper the insert the less friction you will have to deal with

The reason to use the carbide bar is that carbide will not flex as will a "heavy metal bar"!

I've been running lots of 6Al-4v on a HAAS SL-30 for the last couple of months.
On the HAAS I've been sticking to PVD coated inserts & of coarse Cobalt Drills.
I've been successful using the following SFPM & feeds.
Coated Carbide ...160 to 175 SF (Positive Rake PVD coated)(PVD coating stays on
Un-coated...125 SF sharp edges better)
Drills...40 to 50 SF
Ruf Passes ~.10 doc @ .005/.008 ipr
Fin Passes ~.01 doc @ .003/.005 ipr

Good luck & you'll get the hang of it quickly
