Cryogenic machining: Liquid Nitrogen

[Matthew Hajicek - Singularity]

Anyone using it?  Know of any add-on liquid nitrogen coolant nozzles?

Okuma offers cryogenic as an option. They have partnered with a company called 5ME for the cryogenic tanks/hardware, etc. I believe they still have a 800MM table 5 axis VMC on display in Charlotte that has the cryogenic machining option.

I'll probably just set something up with a styrofoam cooler and a hose for now.

We have an Icefly unit from Industrial Cryotec. It's not as sophisticated as the 5ME, but it is much cheaper. Kind of apples to oranges though. The 5ME system uses low pressure nitrogen at around 30 psi, and cools the cutting tool from the inside. The Icefly system uses nitrogen at around 150 psi and sprays the liquid nitrogen right on the tip of the cutting tool. We have only used the Icefly for O.D. turning, and we are using Sandvik tool holders that have the coolant through ports built in. You have to get creative with Teflon tubing to insulate the tool holder the best you can so that the nitrogen remains liquid.

5ME are the leaders in this technology. We tired to partner up with them, but we just couldn't get customers to see the vision of this system. Got a new one this week that in long term might go this route, but you are investing in 5ME when going this route. With the right parts and job it is a no brainier.

For those, like me, who havent heard about this, can you guys explain the purpose and theory behind it?  Ive never hear of this, and I probably wont be using it, but I like to keep up with new tech.  Thank you!
