plus 1 for bar oil as a good sub for way oil. It's easy to find around here at big box DIY stores, farm & garden stores, automotive parts houses, and more.
As to cutting oil I'm sticking with mineral lard oil mixed 1:1 with diesel fuel. It works great for me on a wide variety of metals and does not contribute to rusting issues. For my surface grinder I've gone with a soluble oil and use a refractometer to keep it at a proper ratio. I'd like to come up with a DIY solution to keep the grinding cutting solution at least half way clean. I added an oil filter to my parts washer pump which helps in that instance. I'm toying with the idea of running the return of the surface grinder coolant through a coffee filter or two. Thinking out loud I wonder if an in-line fuel filter on the supply line would be effective & efficient.
