STP or similar works well as a cutting oil additive. It's the EP
chemicals that work the magic.
Hmm, never tried that, but it's very thick.
Right now I use hangsterfers 5418. What say Dan?
Hangsterfers sells an additive called J1 Aldraw if I remember the name
right. It does about the same thing.
But I have seen the STP make a difference in tool life in 17-4Ph Stainless.
I still think it's the extreme pressure additives that do the trick. That's
what the Aldraw is. It used to have a very high percentage of chlorinated
parrifins in it. I don't know with today's regulations what's in it
anymore. But with either the STP or the Aldraw you need a strong pump. It
thickens things up pretty good.
Aldraw also works wonders when ruunning stainless in a stationary guide
bushing. Using an EP additive and a Meehanite bushing you can damn near run
any rpm without the material seizing up.
Oil of wintergreen is also alleged to have some magical effects on tool
life in stainless. I've never been able to find it in large enough
quantities/cheap enough to give it a try.
Prolly clear up the sinuses if nothing else.
BTW, we ran 5418 in most of our machines at IMTS. It was a bit smokey on
some of the stainless demos. We've been using Blaser Vascomill 22(?) in our
shop for a while. It's a veggie based oil. Stinks like hell when it's new
but it's not bad at all once it has mellowed a bit. Works great in
stainless and Titanium. Doesn't seem to stain brass and aluminum either.
It's clear too which helps you to see what's going on. But it is $pendy.
