Platinum Machining


 

I am trying to locate information on turning (lathe) small parts from Platinum 90% Iridium 10%. The parts will be .3125" in diameter and be approx. .050" thick. Initial plans are to attempt this with round bar stock.

Helpful information would be:

Tool Materials
Cutting Fluids
Machining Speed & Feeds
Heat Treating, annealling or stress relieving
Post Machining Chemical Treatments

Hello Frank,

Any luck finding answers to your question? We have an almost identical need with smaller diameter, turning parts below .09" diameter from Pt/Ir 90/10 just over .3" long, no luck searching web yet.

Thanks,
Jim

Hello - I'm a jeweler, and was searching for some clues to this very question from another place. Found these questions, and I thought I'd help you out. I Googled for platinum lathe with no quotes, BTW - found a couple of things, but this: www.johnsonmattheyny.com/technical-manual.php is the most complete.

Johnson Matthey is one of the major platinum suppliers..... Found this thread, too, and thought I'd come back and post the link for you guys...
