Could that be way oil? If not it sounds like you are getting some sort
of
emulsion. Do you check the coolant concentration and adjust
periodically?
A refractometer is an easy way to check the concentration.

It is not way oil. Doesn't look like way oil, and I get it with the
drill press, which has no such oil. It appears that something in the
coolant is absorbing oxygen cand solidifying.

Then perhaps your coolant is partially coalescing or separating in the mix.
I've never had any problem in that regard with the Hangsterfer, but that's
all I've ever used. Mixing the raw coolant with water can be tricky if one
is to believe user reports and/or manufacturer's preparation instructions.
Does your give any special instructions and how closely did you follow them?

Most commercial coolants are good for a year. Now in most commercial
shops..they go through a lot so this problem never crops up.

Get a small 110vt pump, put a timer on it and run it for an hour a day
with the discharge side putting back into the tank at the farthest
location from the suction side.

While this will increase the life span and help keep Booger Lumps from
growing..its not the perfect solution. But it REALLY will help

'In the first place, we should insist that if the immigrant who comes here in good faith
becomes an American and assimilates himself to us, he shall be treated on an exact
equality with everyone else, for it is an outrage to discriminate against any such man
because of creed, or birthplace, or origin. But this is predicated upon the
person's becoming in every facet an American, and nothing but an American...
There can be no divided allegiance here. Any man who says he is an American,
but something else also, isn't an American at all. We have room for but one flag,
the American flag... We have room for but one language here, and that is the
English language.. and we have room for but one sole loyalty and that is a
loyalty to the American people.'
