Wong,
What you have to realise with those types of arbors is that they are made completely from some sort of tool steel, purely because the morse taper has to be hardened then usually ground.
Material like that, even when soft, doesn't turn very well at all.
I get around it by using a tipped tool, at high speed with a very fine cut, finished off with either an emery strip or a toolpost grinder.
It is not your machines' or your fault, it is the material itself.
