Looks like you need a DC motor controller that varies the DC voltage, and is controlled by a 0-10V signal. You'll also need a board to provide the 0-10V signal, like a Digispeed.

I'm not an expert at this, but I think it's right.

yes thats the spindle, so does the spindle need it's own power supply?
like you say the boards need a 10v signal. but the spindle needs 24v-48v, where does that come from?
