Sparks fly when you machine titanium.

Hey everyone, I was surprised at what happens you machine titanium at 3200 rpms. Check out the sparks that flew while machining a 2"x1/8" titanium disc. Some sparks would even combust in mid air like tiny fireworks.

Oooh- that's not good. What kind of cutter are you using? Should also use some coolant. 6Al4V can be a bear to machine but commercially pure alloys machine very much like steel.

It's a plain old carbide bit. Luckily I rarely work with titanium. Thanks for the tip.
Way too fast for the material and tips.

That has to be nasty on your tungsten carbide tools !!!
I wonder what the tool was made of.?
