"If you cut cast iron, cut without coolant and do the same. Otherwise the next time you cut aluminum you will not like the result!"

307Startup,
What is the result?

It has been my experience that cast-iron fines in the coolant will leave a nasty embedding of iron particles in the aluminum. You end up with aluminum that rusts and exhibits galvanic corrosion that starts from the moment the part is being cut.

Bigger shops that do a variety of parts often have a nice coolant filtration system that prevents this from occurring, without having to have material-specific machines or coolant swap-outs. I don't have this luxury.

As I anodize my aluminum at-home, I have had some experience with the problems caused by this scenario...and it was only after much frustration that the light-bulb came on in my head and I was able to remedy it.

Besides which, cast-iron cuts beautifully without coolant, so it's not like you're depriving yourself of any benefits by going this route. YMMV, but I don't like to give out bad advice, free or not.

I would like to start doing that, but I keep running into concerns on regulations and inspections. Feel free to PM me any information if you know of any, hate to start a debate here. basically what I have found is that any product made from anodizing/plating fall under the Fed regulations.... I need good info before I tell the city I am doing that.
