Titanium aluminum (Ti3Al)
 

I just heard of this material for the first time today. It's used in vd
coatings. My buddy needs to cut hocky puck like slugs from a round and I
hear it's difficult. Is there any way to cut it without a wire EDM? Does
anybody have cheap EDM time available?

I'm still trying to talk him into doing a TiN coated saucier pan for me, I
think it would start a trend!

I don't know about 3al titanium, but 6al 4 va Ti is likely to be a
stronger tougher alloy. And I do know something about it. Very much
like Stainless Steel. Work hardens quickly and is strong. But is
machinable on a lathe. Also can be cut with a saw. I have used a
hacksaw on it, but a cut off bandsaw would likely be the best solution
as far as speed and cost of machinery and material lost by the cut. Do
they have a problem with using coolant?

The swarf will burn, but machining is not really a big fire hazard. I
would not let a lot of swarf collect where it could be ignited from
something.

If you grind on Ti, you get very white sparks.

Jeez, when I was a kid, we just used latex condoms. Things must have gotten
tougher!

vd stands for "Ventrified Docilium" and its rate of growth is measured in
furlongs per fortnight.

It's probably Ti-3Al-8V-6Cr-4Mo-4Zr. Tough stuff. Turn around 85-160 SFM
with carbide insert tools depending on depth of cut. It will cut just fine
on an EDM.

:-) :-) A very good example of not defining your abreviations the
first time you use them. :-)
