How is Tungsten/Tungsten Carbide machined?
How is Tungsten Carbide/Tungsten machined? As far as I know it is one of the toughest and hardest materials on earth, so I’m wondering how they go about machining it. My best guess is that they use some kind of diamond/corundum bits but I don’t know for sure.
If indeed there is an even harder metal which they use, what is it and how do they machine that?
It’s diamond tooling.
