Need Help!- might seem stupid

[CORBIN92087]

So this probably seems stupid, but i did a coolant swap on my haas vf2. and im going to fill it now but i cant find anywhere where it tells me how many gallons it holds. i checked my manual and the haas website and nothin. i need to know for my water-coolant mix. any one know this info...?

once again its a 2007 haas vf2

Measure the coolant tank and calculate the volume. I seem to recall it is something like 80 gallons.

US or Imperial?

I see here : http://www.haascnc.com/lang/specs.as...H#VMCTreeModel

there is 55 gal or 208 L

have the same VMC same year , i though there were about 150 L .

The new Haas VF-2 has a 55 gallon tank and I'm pretty sure the 2007 is the same.

Also you should not be mixing your coolant in the tank. I know that everyone does it this way but if you read the side of the coolant bucket. It says to mix it slowly into a smaller container whiles stirring the water then poor it into the tank. You are making an emulsification, sort of like making mayonnaise the old fashion way. This is quite a pain but your coolant will last longer.

Best regards.

or make it like I do , an emulsion mixer ( costs about 120-140$ ) no more problems with mixing it separately .

The coolant/water mixture varies by coolant type, and for the coolant tank are you running distilled water? Running normal water rusts up the machines pretty bad over time.

Ryan, I didn't know that! thanks for the heads up. Just shows you, you're never too old to learn something!

Pretty logical when you think they've added fluorine to tap water.

Thanks!

[Geof]

Ummmm, 'normal' water and distilled water are the same with regards to rust. Whether or not the water is fluorinated or chlorinated is pretty much irrelevant because the fluorine or chlorine levels are so low. The difference between normal water and distilled is that some domestic water supplies have calcium and magnesium, they are 'hard'. These ions interfere with the coolant forming a proper emulsion but they are not present in a high enough concentration to have any effect on rusting.

Gotcha Geof, I was just about to comandeer our coating department's distilled water production unit (we make our own here).

Thanks.

While Geof is correct in his assesment, the problem comes from the accumulation of these hard deposits. Over time these hard deposits will accumulate in the tank mostly due to water evaporation and the machining process itself. Once these levels get to high, they inhibit proper emulsification and then the rusting process can start.

DI and RO water will significantly prolong the life of your coolant and keep it from going rancid longer also. If you have either DI or RO water available I would suggest using it.

To be certain, check with a dedicated coolant distributor to find the best solution for your needs.

Good luck.
