Tin coated will be ok for the Magnesium but for the Titanium make sure the HSS is HSS Co cobalt or forget it.I would use Carbide for both.As for the Coolant.Water Soluble is fine for the Titanium but dont use it for the Magnesium unless you want to chance a Major fire.For Magnesium we drain the sump out and fill with pure cutting oil.Trim makes a coolant for Magnesium I believe but I think its only available in Europe.
I could give you some cutting parameters if you state what kind and size of tools your going to use. |
