What tooling are people using to cut titanium on the lathe? I need to make a couple of threaded adaptors up to fit my pannier racks to my mountain bike and as I have some nice 12mm titanium kicking around that would do the job nicely.
Carbide with a decent edge, positive rake, lowish speed but don't pussyfoot with depth of cut, it work-hardens as soon as you rub it - and coolant, lots of, chlorine-free
You will be pleased to know that I have survived...... Made the parts on my Myford using
Carbide tipped tools, the same ones I cut aluminium with and my usual little spray bottle of coolant. Nothing caught fire and the finish is superb. Surprisingly easy to work actually.
