While this thread is on the topic of coolants, I'd like to know from users of bigger CNC machines if corrosion is a problem.
While I understand that the modern coolant solutions have a fairly good bond to the water, there are a myriad of pockets in a machine where water can evaporate, then condense on an upper surface, This is obviously now pure water, and soon causes rusting. So one might have a vice arrangement running for a week on a repeat job, with flood cooling, and when you dismantle it all, there is rust on underside parts of the vice. So, is this still a problem on modern machines, and how is it overcome?
