Question:
There seems to be some sort of corrosion effecting all of my machines including the ballscrews. There is some pitting but mostly it appears to be staining. The weird thing is that the staining is not just on the surface. What is causing it?

Answer
What you describe happening to your machines is not uncommon. I am not a metallurgist but from what I have seen there seems to be a chemical reaction between some lubricants and coolants and metal machine surfaces. It seems to attack cast iron and steel surfaces with equal vigor. Express Ball Screw Repair reconditions many ballscrews suffering from this condition, some so corroded that it is impossible to remove it all without scrapping the unit. Ask the coolant manufacturers and the will deny the fault is with their product, the same goes for the oil companies, but the condition persists. It is interesting that universities aren't clamoring to find out why. It would make a great thesis for some bright scholar.
