Re: Cutting Oil as a coolant

JFettig:

Well, it has gone too far now. After over a week of continuous circulation, the cutting oil's color has changed from white to purple. I think the density has also increased. Pump makes a vibration due to load now.
Checkout the pics.


You said “The coolant turned to a thicker consistency than paint!" ...what about its color?

bigben2k:

Metals involved are brass, Cu, FeS (or some alloy, for making 'T'). As for the pump, it uses Iron, Carbon, Magnets Cu terminals and small coils. I used solder to seal the block and T. Brazed the reservoir.


blue68f100:

Synthetic oil for Al and yellow metals, is that it? Will it last at least a year? As replacing it every six months is not practical.



What if I increase the ratio even further? A few teaspoons of the cutting oil (which I have at my disposal now) with a liter of water.

And what if I introduce a filter?
