there was a guy who had been doing this for years, mymachinist.com, when they came along with their cease and desist orders and the stress of all the legal battles about killed the guy. there work wasn't as good, nor as cheap, but they somehow conned, er... convinced a judge to issue a patent to this process under the guise of 'extra cooling'. healthy competition is good, but this cutthroat stuff, not so much....... no money from me.
It is, at least to this layman's understanding, a gross abuse of the patent system. It's a machining process. Even with the poor excuse for cooling it's a gross abuse.
It's akin to the idea that someone watched artists put brush to canvas then patented the process of using a brush to put paints on canvas as a process wherein the life of the canvas was improved. It is, to use different words, chicken chit. Some might even some unAmerican and cowardly. Not me though. I'd stick with chicken chit.
