so for a while at work, we have ran the Tormach. so originally we had the same coolant as a Hurco CNC and the tormach is in a small room, which made the EDM guys displeased because it reaks. so we switched it out for the coolant that originally came with the Tormach and it didn’t stink as bad. well finds out that coolant does stop rust that bad. so we took it out and were trying to clean it up.
