Hi all, I have been asked a question regarding the linishing of Titanium bars and the associated risks/controls. I am aware of the risk of combustion but otherwise I'm at a loss. Any help would be much appreciated. Rob.

Wet linishing will remove problems?

Thanks Ron, I had thought of wet linishing. The Titanium bar will be linished with an attachment to a large lathe. My thoughts are if we wet linish the fluid will supress any grinding dust. Rob.

Rob You're right to be cautious. I can't lay my hands on my old dust explosion stuff right now but does titanium behave like aluminium when finely divided? Aly dust goes off with terrific force and also can react with rusty iron in a "thermite" type reaction. I dealt with the melt-down of a unit dust collector from that cause many years ago and there have been major fatal explosions in aluminium linishing as I suspect you know. Sorry to leave this hanging - I need to nip off to a Branch meeting!! (How's that for an excuse?).

As a slight aside, I'm curious as to why such a high finish is required on a bar? I would normally associate fine finishing with cast components like turbine blades?

Would wet linishing not bring in some of its own issues with the possible emission of vapours etc. from the process? Spot vapourisation of the coolant etc.? Paul
