Call me a liar I dont mind I know my facts as far as this chamber and those mfgs goes.
The oven still in use today is one that we use frequently and works well for every application we have a need for. |
Too abigious. What kind of tools? What material was the tooling made out of? What application?
I am honestly not trying to call you a liar, my point is you are making grandious claims about an entire industry with nothing to back it up other than anoymous this and anoymous that.

How do you know that pink faries aren't actually what power your oven? Or that there really aren't magical creatures inside of your car engine pushing it up and they need food and air to do work? Do you see what I am getting at here?
What material are you talking about? Material integrity of what? Different metals, plastics, etc all respond differently to cryogenic treatment. So try to be specific because if you are talking about HSS then yes it does improve the tool. However testing has been done with carbide and there was neither consistant or significant improvement in tool life. John @ 300 below admits this and they are currently researching to find the why but currently it is a waste of money.
The reason I use TiAlN on carbide tools cutting steel is that I will get twice the tool life for only an extra 5 bucks in cost. If your friends theory was correct, which it isn't, then they would have never introduced TiN to the market years ago.
