What is the purpose of this lathe??? Is it good to have??
I was told it would be nice to have one of these. But like the above question.

If you're into racing electrics, I believe that's what you need to shave down the commutator or armature on your motors.

Having the modified motor version of the lathe, I can answer pretty much any question you have about it.

The chief use of a comm lathe is to true up the commutator, which makes a motor last longer. It is usually used when you replace the brushes.

Lathes are only needed if you are racing above club level, and if you are running a brushed motor. Brushless, obviously, does not need cutting.
