That feller there is handier than a pocket on a shirt Thanks for the videos, that was a great way to spend a few minutes of my night. As the son of a machinist and having a family owned machine shop and a serious case of BRD...you already know where my mind is going. Not that it hasn't went there before Edited July 11, 2014 by KKing

What does bar stock of Ti cost? I know it's not the cost, but actually making it happen, thanks for posting!

 

I noticed when he was milling it appears all he did was hit it with compressed air to remove the shavings. I work with a buddy in an aluminum fab shop and was taught to use cutting fluid to keep the blades / bits cool and lubricated. Have seen CNC machines bathe the parts in fluid while being machined. Does Ti have different properties when being machined?

Yes, Ti is different than aluminum or steel.  It's very tough but also can be gummy like copper.  It also depends highly on what alloy of Ti he's using and it's heat treatment.  It's fine to cut it dry (just like Al or steel), he's going slowly, taking short and light cuts so the tool doesn't heat up, and using carbide tools.  He's also using an open mill without coolant capability.  He'd have to put some sort of berm around the mill and would have a heck of a mess to clean up if he was using coolant. 

 

I'd guess that hunk of Ti cost at least $1000.  He's got another few hundred in the cutting tools, not to mention the cost of the mill and the time to do the work.
