Hi, Has anyone done any milling of Titanium. I’ve cut it on the lathe using HSS cutters (sharp) – not too problematic. (Apart from the occasional fire) :doh: Milling it however, I just could not get it to cut properly. :hammer: Small grooves only .003” deep using a 1mm dia mill. I even tried with some engraving cutters, still not successful. Anyone done it, and would you like to share the secret. :bow: :beer: DaveH |

Depends on grades, I make some pump shafts out of Titanium as it's the only thing ferric chloride won't eat. I buy grade 2 as it's the best I have found for machining [ and the cheapest ] It machines a lot like stainless, milling and turning is OK but drilling and tapping can be a pain as it wants to grab and work harden. Was given a bit of grade 9 for a job and it was harder than a witches tits. John S. |

I have a friend who makes titanium exhausts for racing cars i have seen them milling manifold flanges . It seems to machine like stainless . Iwill ask them what grade ect Not machined any witches tits but i would think lots of cutting fluid would be needed :doh: :doh: :doh: |

I have milled titanium, what I've found works best is to use carbide cutters, or if using hss, don't let the cutter rub as the stuff I have work hardens in the blink of an eye. I use light cuts, but that may be down to my mill being a little more flexible than I'd like. The smallest size of cutter I've used is a 2mm carbide, and I have also used a carbide V-point for engraving using extremely shallow cuts, with a little bath of thin cutting oil. Tim |
