So, basically going to make bike axles out of grade 5 titanium. I have talked over with a machineist the best way of doing it and of course carbide tooling is going to be used...
What i am not sure about is heat treating. I am pretty sure you can't machine a heat treated part unless your grinding it down to tolerance. Is this correct?
Alsom is there a massive increase in strength after heat treatment in titanium, i have researched but have not found what i need to know...which is, if making a replica axle of a steel heat treated one, when made exactly the same out of titanium would it be the same strength? Would htere need to be heat treatment?

Also, if any one has recomendations on how to machine ti, i would love to hear it.
BTW, all work is going to be done on a lathe. I will try to get pictures of what i am trying to make..

Any help is useful, thanks!
