Newbie- which motors to run XYZ axis

[RichB77]

I am a newb CNC builder and am currently in the planning and collection of parts stage of my build.

I have the chassis parts for my mill which will be as follows.

300 - 400mm (12-16") X, Y table and ???in Z

It will have a 500W (or depending on availability 710W) die grinder as i wish to machine aluminium.

My question is for the stepper or servo motors running the table and head movements (all 3 axis)

I dont know what spec motor i need. Somewhere i read Nema23 3Nm but thats pretty vague when i look into 3nm Steppers. Is the 3Nm Axial torque?

Any help would be appreciated as this is my greyest area of knowledge (its all a shade of grey )
