Wow only looked at last picture and didn't read first post.!!. . . . . Bloody hell massive OTT like John says. At this size 3Nm on 10mm pitch screws with 70Volts and it will fly.
When you say you want to cut fast, what exactly do you want to cut.? The material and tool used is often the limiting factor regards speed and most machines will travel far faster than the material or tooling will allow.
Just having a high powered spindle isn't always enough and what exactly do you call high powered.?

From the fact you where going to use 1600Oz shows me a few things.?
1: You've been on the American sites too much. . .Lol and . . . 2: You haven't done enough research in this area.

I suggest you post your intentions and desires then we can help save you from buying the wrong components.
Like John says It's common mistake regards motors but it will have a big affect on performance, same goes with ball-screws, bigger is not always better. So post what your thinking to use and we can help steer you in right direction and suggest you don't buy a thing without asking unless your absolutely sure it's correct for your needs.
