I want to add a high speed 4th axis on my machine to use like a lathe. To get clean cuts I need to spin the workpiece up to 3000 rpm (I think). It will also need to have a decent amount of power as I'd like to spin some alrger pieces, up to 20 lbs. I don't know anything about servo motors. My questions are:

Can a servo motor spin this fast?
How big a motor do I need?
Can the motor speeds go as low as 1 rpm up to 3k?
will the motor maintain positional accuracy at all it's speeds?
Where can I learn about servos and configuring them?

I went down this road because I got a SEM MTS30M4-48 servo motor for free. I do not have anything else other than the motor. Would this motor work?
