I have a machine (a dedicated punch tool grinder) with flood coolant, which sometimes sits unused for weeks at a time.
Currently we are using the same water-soluble coolant that we use on our CNC machines (Hocut 795B), but I find that it breaks down if let to sit for too long, and then we have rust issues in the machine.
I'm afraid to use straight oil, because the grinding process creates sparks so I am concerned that straight oil could catch on fire.
Does anybody have a suggestion for a water-soluble coolant that can sit unused for weeks without breaking down? Or a straight-oil that is non-flammable?
