Effects of freezing soluable oil.

[cschmidt]

Hi all,
I am fairly new to machining, I just purchased a BOSS 9 Bridgeport series 1. As summer is winding down, I am starting to wonder what effects the freezing of the soluble oil might have on the pump etc (the pump is a Bijur Spraymist and the coolant I am using is Cimcool Cimperial 1011). I do not have heat in my garage and if prices continue as they are I don't know if I would try to heat it continuously. This is a little different topic but it is still heat related, What kind of equilibration time should I have before I can start using the machine without having it all warped out of shape from the change in temperatures. I live in Minnesota and the temperatures can get down to -20°F, actually I have seen much colder but I don't expect I will be out trying to do anything with temps like that.

Thanks

It'll freeze and bust. I live in MN also. I have one machine in the outside shop. I change the anitifreeze in the car and then pump what I drained into the coolant lines. If I need to run between Dec. and Mar., I currently just run dry. I used to have the saw in the outside shed, I just mixed water soluable oil in with the drained car antifreeze and used that. Don't think I'd do that with a mister.

Or you could rig a way to bring the pump inside with you when you finish.
