In high-volume production today, in the car industry supply chain and in the
making of many consumer products, the hot topics are dry- and near-dry
machining, where tools cutting at 4,000 sfm in hardened steel are throwing
red-hot chips, making noise like a machine gun, and the workpieces are
coming out cool.

So, Ed, what I do not understand is how does the cutting tool;, under
these conditions, managed to stay cool enough to retain cutting
qualities.

So, this is with flooding, just a different coolant substance?

Ayup. I prefer oil over most types of toilet water, but then I have no
disposal problems, living in the middle of the oil fields as I do.

Which tangentially brings up a question, how do you dispose of soluble
oil coolant legally.
