I ordered a gallon of Rustlick WS11 flood coolant about 2 months ago. Cut it with water at 10:1 as recommended and so far so good, except for the fact that I've used the whole gallon already!
Seems like I should get more life out of this based on other's comments here. I didn't measure but it seems like I lose 1/4 gallon every two weeks or so due to evaporation. I have a 3 sided enclosure and a chip/splash shield on the front, no dripping or leakage from the chip tray which dumps coolant back to the reservoir.
In short, nothing ends up on the floor. Drainage isn't 100% efficient, I have some puddling but the chip tray doesn't look like it has a gallon's worth of WS11 film on it...is this normal? Would an oil-based coolant be better?
I'm in the OC of So Cal, 5 miles from the water.
Suppose you were an idiot and suppose you were a member of Congress. But I repeat myself.
your complaining about 1 gal in 2 months WOW
sounds like your getting a deal , in one machine I put in 5-10 gals of mixture a week.
in the summer i go through 5 gals of pure coolant 1-1.5 months on one machine, in the winter I go through about 3-4 gals 1-1.5 months
if your face milling you will loose lots to evaportation.
my chips come out pretty dry, what I have noticed is that alum will use more coolant then steels stainless or nickle alloys
You are of course loosing a significant amount to carry off, which is coolant attached to the chips.
In my case it appears to be more than evaporation, especially when I did some Lexan the other day, the chips were coolant colored and where very wet. I let them sit overnight and they were the same.
If I did a lot of Lexan I would like to put them in a press to squeeze them dry, or a centrifugal dryer, to spin them dry. Since my Lexan was a one off job for me, it is not a big deal.
Warning: DIY CNC may cause extreme hair loss due to you pulling your hair out.
You also lose coolant because the machine creates a fine mist that drifts away and settles on everything; which is why eventually everything in your shop gets an oily, dusty film on it.
But as mentioned your loss rate is nothing unusual.
An open mind is a virtue...so long as all the common sense has not leaked out.
