I came across this doing a search about mist systems. I personally have been turning screws Since 1967 and I hate mist systems. Would not have one, I use a High pressure coolant pump as my secondary coolant output if I need a second source. (Sorry, I just detest seeing that function on any machine) Shows me they have a lot to learn about this business, LOL If I had my druthers I'd setup most all machines with cutting Oil. Lot easier on the machine, doesn't rust, get stale, smell god awful and wont remove paint.
Quote from another source:
After 40 plus years of smoking three packs of Camel's a day I thought my lungs
were immune to anything.
Then I bought what became Express Tool & Die, and "inherited" spray coolant
systems on every machine.
Within a few days I was in severe congestive lung distress. I noticed every one
of my machinists wore masks while machining and IMMEDIATELY had my shop guy
collect all the mist systems and put them in the next scrap run.
I "decreed" that flood coolant would be used in MY SHOP, paid whatever it cost
to set up decent systems, searched for a coolant base that met our requirements
(it costs four times as much as the regular Valcool stuff) I have the Rep come
in every week to test and adjust the mix (free unless I need extra base which is
rare..this stuff holds up beautifully)
The solution is a translucent blue, not an opaque white or pink, the rust
protection on the machines and components is superb.
Coolant is as important to accuracy as the type and grade of tooling and
machines used.
It sure as hell isn't worth the REMOTEST risk to your health!!!
FWIW
