Does your machine flare by pushing in a die like the small hand held ones? Ones I'm familiar with have a cone shaped die that spins. The axis it spins on is offset from the center of the tube.
Yes works just like a handheld tube flare just a lot more pressure (tubesnhoses machine),double flares no problem with aluminum/copper/steel but SS can be brittle and crack or split also some SS tubing has a welded seam which has to be checked after flare for imperfections,
also use a handheld hydraulic flaring tool(for on the vehicle repair)and it also could do the job, all depends on the softness of the tubing you have,check out inlinetube.com they specialize in brake lines.
Last job I did on my airplane that involved tubing was to install an aux tank and all the tubing is aluminum and single flare,hope this helps,cheers
