cryogenic tempering

[Surface]

20 years ago, I remember learning a little bit about cryogenic tempering in metallurgy class. At the time, it was understood that cryogenics had some effect on the micrograin structure of a metal, but it was mostly theory and it wasn't going to be on the mid-term, so I never learned much more.

In the past few months I have received a few "cold" calls from people offering this service.

Although they are offering a free trial, the majority of my work is prototype/small-run and it would be difficult for me to quantify any improvement of tool life.

I am curious however if anyone has had any experience.

We have a cutter grind source that does this to all their carbide and hss tooling.Free of charge if you buy the tool from them or have them re-grind a tool.

endmills,drills etc....

they say that it quadruples the tool life.

I have yet to see that because I keep smashing tools before they are dull.

I also talked to an owner of a company saying triple tool life. Even works on brake rotors. I called robb jack and they said on low quality carbide it should help a lot, but theirs is so high quality, that when they tested it, it didn't shows signs of improvment. They said it would be a waste of money for their tooling.

I think there was a big thread about this a year or 2 ago; did you try a search? At one of my former employers we tried this on M2 stamping tools and didn't see much difference.

A High School friend approached me with this a few years back. He bought into a frachise called Cryocore. He was serviceing a cabinet shop treating all there carbide router bits. From what he told me it trippled the life of those tools. I let him treat a HSS e.m. for me but never got he chance to test it because the placed closed up. I do know that my buddy does not have the business anymore so either he just couldn't sell the idea or it dodn't work well enough for people to buy into it.
