What's the best coolant?

[Guyinthedesert]

Thanks for all the replies and suggestions. We are going to try the Hangsterfers S737. Keeping my fingers crossed.

What's the deal with not using chlorinated coolant when cutting Ti? I've never heard of that until this thread (but we cut basically no titanium).

I've been using Dascool 2357 for about 5 years now

Used to use S500. Foamed toooo much

Tried Cimcool, Castrol, Blazer, Et all. Most of them caused my hands too much grief.

Been very happy with Dascool.

Not real easy to find, but well worth it

That's all I cut anymore, from what I understand the chlorine causes micro tears in the Ti do to heat and chemical reaction. To be Boeing, Pratt,Goodrich ect. certified (not just compliant) all coolant used has to be free of any trace amounts of chlorine.

We use Dascool 2900 - used to be from Stuart Oils until they got bought out.

But it's a real good all-rounder. We did a back to back test on 2x identical machines running the same parts and got twice the tool life on stainless against the previous coolant we ran but I can't remember the name - DOH!

Anyway, the dascool doesn't foam has never gone off, handles oil in the sump well (as both lathes are box way) and it's gentle on my skin!

Also it doesn't stain ally

Has anyone using Hangsterfer's S500 had brown staining inside the machine? I've been using it and the inside of my mill is turning brown. If you've had trouble with this how did you get the brown waxy coating off the inside of the machine? Also, how are you guys, using the S500, mixing it? Do you use a simple $30 mixing valve or a high dollar mixer from Hangsterfer's?

[Thee Dragracer1951]

Yes the Hangsterfers turned the sheetmetal brown.

It cleans up though.

I use a cheap mixer.

[cincy k]

How'd you clean the brown?

 

 

[Thee Dragracer1951]

Tolt the shop helper to get that machine clean.....

 

Simple Green works pretty good

[Pilot Plant Supervisor]

I got rid of the brown by switching to S737. We use the cheap mixer here as well.
