How to avoid stinkin' coolant? | |
This is concerning a small (apx. 1000Kg.) toolroom mill, but now only used intermittently as a hobby machine.
I have torn down and built up my mill. This included cleaning the coolant tank, which is actually the lower part of the main casting. I scrubbed it as good as I could using a strong caustic solution that is used on walls before painting. There was a lot of slimey goop in there, and I tried to get everything out.
Is there anything more I can do to avoid that goop to get back to life when I put in coolant?
The last coolant used (don't remember name) allowed this goop to grow. The previous one called Zeronite did not. But on the other hand it was not very nice to the paint. Can anyone tell us what different "families" of soluble oil coolants there are, and the pros/cons.
Should I drain the coolant tank during periods of little or no use, and store coolant in an airtight container? I guess these aliens need oxygene to breed. |
