Thread: Coolant mist

I work in a small shop with 2 VMC'c we make our own parts for our machine we market and sell.

We do mostly aluminum. We have a 3 inch 6 insert mitsubishi facemill that we run at 6000 rpm, when the coolant turns on it mists up inside the sheet metal and i can see a haze when looking at the light inside when changing parts.

We use blaso 2000CF coolant.

I havent seen how any shops handle this.

Is this unsafe for me to breathe this? if so how can i fix it?

I was thinking a blower on top going outside making fresh air getting sucked into the machine

My workplace is not cheap and if i showed then it was hurting me i am shure they would fix it.

PS hey Pi how can i get access to your hub?

yup
use an exhaust fan. run duct pipe to machine. have a fan blow mist into your employer's office.
tell him it is ok to breathe it unless he can prove otherwise.

this works for nasty coolant, too. just fill a coffee can full of foul smelling coolant and hide it in his office.
have you tried emailing me? bargaincnc@lycos.com

A buddy of mine works in a production job shop. lots of aluminum, lots of small insert shell style cutters. He went to the doctor with some upper respitory thing and the doctor, knowing he was a machinist, asked him if he used water soluble cutting fluid in a spray mister. Apparently they see enough of this to ask the right questions. Any kind of flycutter style tool atomizes the coolant enough to float on air. The tempature of a coolant tank is ideal for growing bacteria. So the real question is how much airborne bacteria do you prefer to ingest? Your general manager can probably sanctimoniously quote the MSDS sheet on how safe it is but that is before you added it to your last batch of sourdough starter. Pi's solution seems the best to me. Until one of the shop gentry is hacking HIS lungs out you probably won't see much change.
