Anyone here have ever tried cutting 304 stainless steel or titanium on their Sieg x3? Do you suppose this machine would be capable of doing it?
I have done this on a bridgeport mill, but I do not know if a Sieg x3 is capable....I wan't to get one for my small basement. Bigger mills are to big to fit

i have never seen even small milling machines that could not mill Stainless. All machines have a horsepower and force load that they can take which rarely has any thing to do with the machines motor.
in general small machines can only take 1/4 hp load or less but the thing to remember is also the forces involved.
basically at higher rpm with carbide end mills that are using the same hp the force or load at the tip of the end mill is less than at slower speeds.
so try a carbide 3/16" end mill, instead of a 3/8" HSS end mill. also use short length end mills which can take more than longer length end mills.
i mill very often 3/16" dia and 0.010 Depth of cut on a small Sherline mill. if you ever get vibration or chatter try a smaller diameter end mill first, then a slower feed, and lastly a slower rpm.
